newbie trying to get a 283 to run after 9 years in storage

I'm trying to get my GMC pickup on the road after being stored for 9 years. It's got a SBC 283 that a buddy helped me install in 1982. After reading lots of info, I decided to put Marvel Mystery Oil in the plug holes, remove valve covers and pour Marvel on the rockers, change the oil, pull the distributor and spin the oil pump via the distributor access and then rotate the engine by hand to get the motor to turn and check that it's not locked up and that all rockers/valves are moving. I realize this is probably overkill, but want the best chances of the motor running well for awhile, since I can't afford a new motor right now.

That said, I realized I have a couple things I need help with. First, how do I mark the distributor for removal? I've had big headaches in the past trying to re-time an engine after messing with the distributor. I realize it's not that complex, but I always have problems with it. If I mark everything, when I spin the oil pump via the distributor access, will this mess up the timing, meaning I'll have to find tdc, etc, anyway? Where can I get one of those drill adapters that will spin the oil pump?

Next big issue - how do I rotate the engine by hand? Is there a place I can put a breaker bar or a socket with a breaker bar to rotate the engine?

Lastly, the quadra jet carb that's on it (probably circa 1982) was spitting fuel all over the place when I parked the truck, so I plan on replacing the carb. I'm told an Edelbrock 500 (Performer, I think) is a good reliable replacement. I'm looking for a good running truck with decent power, until I get the cash to build a fast motor. Will an Edelbrock Performer work with the current intake manifold (set up for a quadrajet), or will I need a new intake manifold to match the Edelbrock?

Thanks!

Well first off welcome to CHR When I remove a distributor for your purposes I bump the engine over till the rotor is pointing to the firewall I mark the firewall at that point and remove the dist. AT THIS POINT DO NOT TURN ENGINE OVER TILL DIST IS BACK IN. After turning the O/P you will probably not line back up with the pump rod. Turn the pump rod with a screwdriver to line it back up so the dist. drops back in and the rotor lines up with your mark. I have done it where the dist. dosen't line up with pump rod but have the rotor where you want it. At this point the dist. is in the cam where it belongs you can have a person bump the starter while you hold the dist. down and it will drop in where it belongs. Turning the engine over can be done MANY ways with the plugs removed the starter will turn it over easly . You can remove the belts and use a strap wrench. I don't recommend using the crank bolt. I'm not sur about the 500 Edy but it sounds about right Have fun

283 is probably not going to have a crank/dampner bolt.
But as Charlie said, with the plugs out the starter will spin it easly.

Welcome to CHR!

The venerable ol’ 283 is quite the survivor – several folks here comment on them on a regular basis. The oil steps are fine and if you’re squeamish about the alignment of the distributor, leave it in. Pull the plugs and pour a bit of oil in each cylinder, pour some across the rocker arms and then turn the engine over by hand. You can buy this tool from summit Powerhouse Products POW103090 - Powerhouse Products Engine-Related - Overview - SummitRacing.com or go to your local NAPA and buy one that’s similar. Turn the engine over by hand 25-30 times and then hit the starter for a few seconds. Listen to the spin and if you have an oil pressure gauge, you should see it register at 5-10psi. Repeat the starter for another 10-15 seconds and everything should be oiled ok. Drain and refill with good oil (new filter too) and you’re set.

As to the carburetor – Edelbrock no longer makes a QuadraJet replacement and a 1406 is a square base. Your QuadraJet is a spread-bore and there will be fitment problems. I’d recommend a rebuilt QuadraJet like this one Summit Racing SUM-210216 - Summit Racing® Remanufactured Quadrajet Carburetors - Overview - SummitRacing.com $270 and you’re set. It’s a 750 but the design of the QuadraJet with small primaries and larger secondaries allow it to be used on a wide variety of engines. This one has an electric choke that is hassle-free and just needs a switched 12 volt source.

I would also encourage you to think about replacing the distributor – 1966 is still a point type with vacuum advance. This HEI is $90 and coupled with the rebuild QuadraJet will be money well spent. Summit Racing SUM-850001R - Summit Racing® Blueprinted HEI Distributors - Overview - SummitRacing.com Again, a 12 volt switched supply. Make sure the vacuum advance canister points in the same direction as the stock distributor and that the rotor is in the same place as the as the existing one. Time to 8-10 degrees initial and you’ll be very pleased with the trouble-free performance.

Have Fun,
Glenn

If you replace the points distributor with an HEI (which I highly recommend), then run a fresh electrical line from the switch to the + on the HEI. The existing electrical line that feeds the + terminal on your coil is either a resistance wire or has a ballast somewhere in the line. This is so that, with points, you get 12v at startup and then the voltage drops to protect the points. This arrangement will not work well with the HEI, which needs a full 12v ALL THE TIME. Even a boneyard HEI will probably perform better than the points arrangement.

Here's the tool you will need to turn the crank. Remove the belt pulley(s) and bolt this tool to the damper.

While you're fiddlin' with the motor, you may as well verify the damper inertia ring for TDC. If it has moved in relation to the hub, you will never get the motor timed properly with a light....

Thanks for the great info! Is there any reason I can't rotate the motor by putting the 4 speed in 3d or 4th, raising the rear end and spinning the rear wheel? I'd rather spin the motor by hand then with the starter, just to be careful. Thanks for the links to the pully attachments to turn the motor, but I don't want to spend extra money, and I'm not patient enough to wait for shipping.

I'm sure I'll replace the distrib and ignition once I get the truck running and back on the road. Is a new Q jet as complicated and difficult to work on as the old Q jet I've got? If so, I'd rather get a new intake and edelbrock carb, since my current Q jet is to complicated for me to mess with.

If your Hercules you might do that!

You will need to use the proper type of oil priming tool if you decide to turn the pump to prime the system. A plain stick like this one....
Moroso 62200 - Moroso Oil Pump Primers - Overview - SummitRacing.com
will not close off the passenger side oil galley and you will not get any oil to the passenger side rockers with it. You will need this type....

Actually son, I'm a little concerned with the attitude you have concerning this entire project. You don't want to learn how to time the motor from scratch, you don't want to spend a few bucks for tools, you don't know how to work on a Q-Jet and are unwilling to learn. I don't know, it seems to me that you should make a decision at to whether or not you want to continue. You're lookin' for the easy way out and there just ain't no easy way. You either roll up your sleeves and learn this stuff or you ride a bicycle. No need to get your nose all out of joint over what I'm sayin' here either. I'm all about REAL and you need to be about REAL also.

Well Pops (techinspector1), first off, I appreciate your ideas and input just like all the other great input I get from this and other sites. However, over the years I've realized what I'm good at and what is difficult. I've also learned not to add complications.

At this point, messing with the distrib could be a complication in getting the old engine to run - so best to avoid that. Plus, I was told in the past that my balancer may be off, meaning the timing marks may not line up - another reason not to mess with the timing. At some point in the future, if I do more indepth engine work, I'll probably learn about timing the engine (been there, done that on many motorcycles, but it took awhile).

I've never liked the Q jet, and don't want or need a high performance fuel system. I'm happy with something simple and reliable, which I'm told is an Edelbrock Performer. If you consider that "the easy way out", so be it.

I figured I could save the time and money involved in buying and hooking up a pulley attachment by simply lifting the rear end and spinning the wheels, although 34_40's comment indicates this will be more difficult then I thought. I figured with the plugs out, it wouldn't be to difficult to spin the motor - I guess I'll find out when I try it. Maybe I'll have to order a pulley attachment and wait for it to be shipped (local speed shop doesn't have them in stock).

So, if you think I should stick to riding bicycles (I ride 2 or 3 times a week), your entitled to your own opinion. I'm using this forum to learn all I can and minimize my mistakes. If I cut a corner or two, and it doesn't work out, I'll do it different next time.

Btw - thanks for the headsup on the correct oil pump primer -this is the kind of info that I appreciate on this site.

Where are you at in NorCal? If you are close I would have no problem coming over and helping you. SBC engines are about the easiest things to work on there is.

FYI, I would make you do all of the work with me supervising. That is the best way to learn.

Q Jets are either good or bad. If you have a bad one, scrap it and get a new one. That has worked best for me in the past.


Oh, BTW, techinspector1 is one of the best people to learn from on this site. Don't bite the hand that feeds you.

Bug hit it on the head. You're not the first to dismiss him so lightly.

A super easy way to check the balancer: pull the sparkplug on # 1 cylinder, and put the motor on zero on the mark. Put a screwdriver in the hole and feel for the piston top. Rock the motorback and forth, and feel the piston. It's pretty easy to figure out where the piston is at top dead center (tdc) when you get te piston at tdc look to see if the mark on the balancer lines up.

Since you aren't going to buy tools, and aren't building a top dollar motor, just put a wrench on the crank and turn it. It's only worked for me for about 20 years.

Now, go back and look at what tech said, and see if you can use the wisdom he shared.

Well, since the OP has been back on the site but not replied again on this thread, I guess he does not want any help.

Oh well, we tried.

Funny I read this thread right before work and didn't have a chance to chime in. I get what he was asking in avoiding adding to reasons why car might not start by doing too many things at once. I think everyone offered good advice and alternatives. What I still don't get is why would you want to even try turning an engine over with the car jacked up in high gears? why not simply put it in neutral? That was his one train of thought I couldn't follow at all.
So if your still out there, maybe try this approach first then proceed with some of the above modifications sugested. Lube each cylinder with some fresh oil, after changining out the old oil and filter. Put a breaker bar or long wrench on the crank bolt( with car in neutral, and plugs removed, and rotate the engine 25-30 times like suggested. At this point you will have a sore arm! Add a little gas to carb, and have a friend standing by with some starter fluid, after reconnecting the plugs and wires. Try to get her to cough or turn over. If she starts briefly and stops, all is well. Now address the carb issue. You know the car can start, and you know the old carb leaked, so go ahead with whatever carb choice you have come up with that fits your setup. Edelbrocks will usually work right out of the box with their factory settings.. put on a new fuel filter before trying to start, because god knows whats going on in the fuel line and gas tank. If you think your rust free and the gas is relatively fresh, give her a start up. Otherwise consider draining the tank, and using fresh fuel. If she runs after this, then maybe just flush your radiator and engine out put in fresh coolant(probably want to replace the hoses too and the belts, 9 years is along time for rubber). Then just do your regular systems checks to make sure your brakes work, your engine charging system works and your battery is good. Give it a test drive in a relatively quiet open space encase brakes fail, etc... And you should be o.k. for a while until your ready to address any mods like the distributor or other issues that may arrise. I hope this is helpful?

Too many different directions here

First charge up the battery
while seeing if engine will turn over check for spark
if you have spark, spray a little starting fluid into carb while cranking to see it it hits a couple times--if so, timing is close enough to run
fix up fuel system---fresh clean fuel in tank, new filter, check pump out put/pressure, fix carb--a carb kit is cheaper than a new carb/manifold---prime carb, crank engine with starting fluid---- if it starts and runs, warm it up a little and then drain oil/coolant, do general periodic maintaenance--belts,hoses,plugs/wires/cap/rotor---------

Jerry,

You are correct and you just added another one to it. A good direction, but another one.

When someone posts a thread like this you could get 100 different directions from 100 different people. The OP just needs to sift through it and see what they can use.

Me, I would not use starting fluid. I have seen starting fluid dry out the cylenders and make for harder cranking. I would use a watter bottle, like a Crystal Geyser or such, drill a small hole in the cap, put a small amount of gas in it and use that to prime the carb.

But that is just me, and another direction:).
