Thread: help me out!!

Tweet

Ok, have an '82 (or something) Camaro that I took on trade. My significant other wants me to build it for her. Engine has been changed, the casting number on the block is 14101148, Mortec sez it's a one piece rear seal 350. It has the tall lifter bores, so that would make it a roller cam block, right? (Currently has non-roller hydraulic in it).

Well, got to do some go fast stuff, thinking a roller cam, specs unknown (I'm a Ford guy) and a set of 200 cc runner aluminum heads (or thereabouts). The engine has to have good power, and still be very streetable. Can I get away with 10:1 compression, and how much cam will this thing want???? Also have a set of Hooker shorty headers, fairly equal on tube length going into a 2 1/2" 3 bolt flanged collector. Tranny is a 700R4.

Thanks in advance for the help (and yes, I do expect a bit of abuse on this project, too!)

okay go for a set of flat top pistons, deck the block, to decrease quench. Heads, hmmmm if new a set of edeldock performers matched with their performer camshaft. With the raised camshaft block you will need to probably run the shorter pushrods and to get your valve geometry right. I will have to look into the camshaft specs some more, what revs do you want to run in ? so being a street car I am picking you want to build plenty of torque with it. Right ?

Yeah, I suppose I should just make it a 383, huh? Still the most cost effective method of getting torque out of a small block chebbie. Far as cam specs, I dunno. I'm a Ford guy. Erik has the details on the heads, maybe he will jump in here later. Like I said, I'm a Ford guy.

Dave, if it looks like the one below, it is a roller engine. The little raised threaded areas are for the lifter retainer to bolt down to.

So your significant other likes speed, huh? Cool.


Don

Yup, that's what it is. No idea how it ended up with a regular flat tappet hydraulic cam in it.....

Dave,I would look at some CNC'D heads that have a port volume in the 185-195 area.
You talked about running a roller cam.Mech. or hyd.?
If you think the engine will see 7,000 then I would only look at the mech. roller cams with a small base circle.
To try and cut down on the valve adjustments I would limit the valve lift to .600.
It will save you a few bucks also in the valve spring department also.
In the past 6 or so months I have run a lot more of the Lunati goodies.
I would look at Lunati's VooDoo roller cams.
We have used part number 60133 with very good luck.
This was in a 6 in. rod 383 10.5 to 1 engine with a set of 195cc CNC'D heads,Victor intake,floed 650 double pumper.
The guy had it in a 81 Camaro with a 3,500 stall and a 4.10 gear.
One of the last race's of the season he drove it to the track over 50 miles round trip and bolted on a set of 26 tall slicks.
The car was running 7.10's in 1/8 mile with some tunning.
While this does not sound that quick keep in mind he drove it there on pump gas.
On the nice day's he was driving the car every chance he got.
While the engine was never on the dyno I would guess it made an easy 500 hp.

Would this be ok with the 700R4 that Van's is setting up? He'd prefer to see me stay in the 400 to 425 horse level.. Maybe just backing off to a vacuum secondary 650 would help with the driveability and make the OD trans live a bit longer???? Got to stick with the mechanical rollers, such cheap horsepower, all things considered.... Gonna go look at the VooDoo specs. I'm sure you (Erik) got a line on just the heads I need?????

Dave,with 400 to 425 hp yo don't need a mech. roller cam.
At this hp level I think you can get it done with a large hyd. or a small mech.
Even a small mech. roller will push you above the 400 level.
Yes,a vac. carb will help out a lot.
At 400 hp you need a 180 cc head to get the job done.

a lot of the gm truck came this way . roller block and flat.yes it a roller block i justed did one that came from gm with a flat hyd cam .this is now a roller engine yes the shorter push rod spider for the stock lifters and retaning plate for the roller cam if you go with the small bolt pattern on the top gear for the step nose cam i would use that type of cam and the stock gm roller lifters and the gm retaning plate for the cam and timing set and a set of custom push rod oh do not to forget to run the gm melonized gear for the steel core cam if you use a gm core gm

K, maybe I'll look at some of the hydraulic and hydraulic rollers, and put all the old hardcore mechanical stuff back in the boxes!!!! Maybe the next one. This one has to be civilized enough to live in traffic, cruising, and some touring.....

Sure do appreciate the advise, now I have to go study up on these 700R-4 trannies to see what I need for goodies in it, and what I can run for gears in the 9"... Heck, you know I had to get some Ford stuff in it sonewheres!!!!

hey dave what is the world coming to you working on a chevy and me on a ford the world must be ending just took a job in a ford flat head . to re machine and rebuild

Egads!!! And now I own 2 Camaro's!!!! Something must have gone wrong, maybe the whole world jumped a tooth on timing!!!! Next thing ya know I'll be chopping the roof on Uncle Bob's lightweight Mopar!!!!

oh well at lest it US steel ? well i know the flat head is. have fun. dave them chevy are not that bad if you can make a ford run . chevys are easy. you can put all them chevy parts in a big box and shake it hard and they go together

Sure do appreciate the advise, now I have to go study up on these 700R-4 trannies to see what I need for goodies in it, LOL: [/QUOTE]

I would look at getting some heavy duty clutch packs and a light shifter kit, pull up some corvette TH 700 codes and specs and compare them to your trannies code and specs, I know that some of the high output corvettes had heavy duty parts in the trans.

Here is a good 700 r4 site that list all the parts and prices and different hp levels each part can handle.Looks to be pretty complete on all options.
