h0trod one of my friends was in this exact delema.

he wants decent power for his 57 chevy belair.

i told him the best way to learn is to do it yourself.

ive built a few engines in my day, so i called up summit and ordered the rotating assembly (fully forged).
ordered edelbrocks 460 hp top end kit.

we took a core 010 350 block to the machinist, and he wanted 900 to do the machining.

i called up summit, and got a roller block 4 bolt main, for 800. fukky preped for a 383.

we have 4600 into the engine so far, minus carb, lifters, rockers, pushrods, and goodies.


you can get a 425 hp create engine for 5600, so the prices are about the same.

knowledge is priceless.
tools are pricey but last a life time.
the warenty these guys claim to give you is based on a liscenced shop doing the work.

fwiw

vinniekq2 get a piece of paper and write down everything you know that you will need and what you expect from the 383.
The figure out how you will tune it.
Then consider a totalled donor v-8 car for all the items you will need,like mounts/wiring/rad if possible,,,,the total costs might be higher than selling your car and buying another car in good shape

you want to drive it, or look at it..
put a gen 1 small block in it. and you can look at it all you want but never drive it..
you can tow it to a track.. but it'll never see the street.. legally..

Pauls_camaro Yea there is no budget and I'm going to be doing most of well all the work besides the machining
An do don't want just a ls1 to simple of a solution .
I've worked on 350s for a long time just have never made a 383 or done a v6 to v8

Probably the best information or advice anybody can give you right now is to figure out exactly what you want, how big a budget you have and take it from there. Everything your talking about doing costs a fair amount of cash unless you can do the major amount of work yourself or have friends that can do it for you for free.

If that's your main concern than it doesn't matter if it's a 283 or a 383.

69 widetrack I'm sure I don't need mention this but just in case. If you buy a crate engine from a builder make sure you choose one that has a proven track record...both with building the engine, producing the longevity and power that they claim and how they stand behind what they build with respect to warranty. Anybody can offer you the moon when it comes to warranty...offering and coming through are two different things.

techinspector1 Crate motor.
1. Easy
2. Cheap (comparatively)
3. Warranty

69 widetrack Again X2 on every post. I've built countless engines in the past, the real long ago past, the last engine I built that went fast was a 428 Pontiac...that was over 10 years ago. I am now in the throws of a another Pontiac build and when it comes to the engine...I will build it...but, I'll have the pros watching every step, looking over my shoulder. As Vinnie said, I don't know how to unlock every bit of free Horse Power...and watching Horse Power TV...well that's great but wait till you start building and one little thing you forgot...Oops, NO warranty, that's where you say woulda, shoulda, coulda.

Doing it yourself the cost of machine work usually exceeds the cost of parts. Of course once you buy good tools they are yours for life.
^X2...the value is with the crate engine. if you want this to be your FIRST build, then it would be wise to start with a simple rebuild. jumping into the horsepower ring with absolutely no experience is not a very good idea especially cost. valve spring tool, chicken foot, ring compressor, torque wrench, engine stand, cherry picker, measureing equipment etc, etc... and a ton of pestering questions aimed toward the pros. stick with the crate unless building an engine is your passion then stick with the value...the crate.
