NEW TO SITE!!! Want to build 383 chevy

just wanted to say hey hows it going. also that i wanted to build my self a nice street/ strip motor for my 86 cutlass.

im not very educated in engine builds so i figured you guys will know alot off stuff that will work and has work beautifully in the past. i also realize this has been covered many times so if you wish not to help me out no big deal but please write away if you want to.

So heres how it goes.

- want to build 383 for sure
- car will be driven on the street but not huge amounts of kms/ miles ( not only car so maybe less then 30 a week)
- thinking mid 12's to high 11's at the track
- tranny will be a freshly rebuilt TH 350 ( stall not decided till after)
- gears are 373's ( posi of course)
- also debating either nitrous , turbo or blower ( think there the same any ways :P)
- price wise also has to be in moderation ( under or close to 6000 canadian)
- i really want somthing that rips it hard on the street and runs a decent time at the track

I have went over some combos but still havent really decided on what i should do. so please if you can help me out that would be great.

thanks for reading and i hope i can come back to this site in the future **)

Big Truck Driver beat me to it :LOL: If you want the best bang for the buck, take a look at combo #42, iron heads are cheaper than aluminum. Never mind the horsepower, look at the 452 ft./lbs. of torque @4,500. That'll yank ya back in the seat for cheap!!!

Ryan, has a lot of good combo's.
I also would add a few of his combo's have to large a cylinder head port volume.I.M.O.,the engines would do better with a smaller port volume in the first couple of builds.
Also don't use the short 5.565 400 rod when building a 383.Use a 5.7 or a 6 inch instead.
If you want to add n2o have the cam cut on a widder l/s such as 110 also favor the exhuast by 10 degree's over the intake depending on how much you are going to use.

Got any parts or building blocks for this motor yet ?
10-21-2006, 04:45 PM
BinJim

well bascially all im gonna use is the block, pullies, headers, and see if i can still use the rpm air gap. but every thing else will be new cause i dont like messing around with used parts.

All external dimensions of a 383 are the same as a 350 so you can still use your rpm air gap.

Say Eric, you say you have built lots of 383's what do you think is a better set up the externally ballanced crank kit or the internally balanced crank kits. I have allways run with the internally balanced kits.

i might still use the air gap but not sure if i will depending on the set up i go with.

alright so all the engines from ryans car page are made for the street right. but from what iv been told you have to run race fuel when you hit that 500 hp range? or is the only thing that makes those set ups street is the cam/ lifters combos and im assuming they perform at lower rpm?. so then what gas to run isnt an issue in desciding for street/ strip?

You know, it "used to be" that 400 hp was the maximum that anybody said could be used on the street. Sort of like what Bill Gates said about 10 years ago We have 800Mb's of processing power (or some x figure cant remember exactly) that should be enough for anybody.......yeah right.;)

_________________________________________________________

:HMMM: But if you are mianly using this car for street fun and the occasional drag shootout, then the thing that moves you is torque more than horsepower. Torque is all about pulling power starting at moderate engine revs and having a good power range. So the 383 stroker is a good choice for achieving this. If you want to go for horsepower it is usually a high reving narrow torque band screamer. And the higher the engine revs the harder it is on parts like valve springs for instance. So there is more time and money spent on maintenance. **)

You'll notice that all the static compression ratios are between 9 and 10 to 1. That, together with selecting the proper intake closing point on the camshaft and a good tight squish of 0.035" to 0.040" will allow any of these engines to operate on pump gas.

Whoever told you that you would require racing fuel at 500 horsepower may not have known what he was talking about.

I was thinking the RPM Air Gap would be great on the street,and maybe a open plenum intake would be best on the track.Unless you have like a real heavy vehicle.

i do want the higer torque but i then also will be running the higher hp on those combos that he showed. so then those will be able to run on pump then right ? casue i really dont want to have to be restricted to only race fuel. i would like to keep the rpm air gap cause its range is i believe idle to 5500 or so.

You can also spin it faster.

It is always better to int. balance.
For one thing you don't have to run that heavy harmonic balancer on the snout of the crank.

The September 2006 issue of Hot Rod Magazine had an article regarding building a 500hp 383 for a $5000 budget (is that $2,000,000 Canadian?).

HRM is notorious for lying about horsepower, torque, cost, part sources, part specifications, etc. so you can believe that whatever they did will cost more for you since you dont have "friends" giving you stuff like they do.

think iv come to a conclusion though.... going to go with set up 42 from ryans web site there but gonna add a carb spacer, bigger cam and use the rp air gap.... any other sugestions?

Try shoving some compression and some rpm's in there and see what happens.
It is not a question of if, it is a question of when:whacked: :HMMM:

It is o.k..but I.M.O. the heads are to big.
I would look at heads that have a port volume of 180 cc.

well if 12:5-1 compression and 7500 or more rpm's doesnt count i dunno what does. btw the old 301 that was before this one was drag raced every single weekend and street driven for about 8 or 9 years and it was very consistent, it finally spun a bearing because it still had the front sump nova v8 oil pan on it! the walls were perfectly fine for another rebuild. so what do i know:rolleyes: ................ woo hooo 1400,dredth post!
