Im new to the forum and new to building my own stroker motor. Ive done plenty of searches concerning the 383 and know the basics such as clearances and piston lengths and cranks. What I DO NOT know is how to build a engine from block up, the RIGHT way. I know what all parts I need and how to make good power, just never done it. If anyone can steer me in the right direction or maybe a older post that I have over looked. My planned parts are as follows.

4 bolt main block bored .30 over
either Edelbrock 185cc intake, 64 cc CC heads or AFR 190cc street heads
Keith Black Hyperneutic Pistons
Comp Cam hydraulic roller, 230/236 duration @0.050 lift (clearance problems?)
Scat 383 crank
Comp cam self aligning roller rockers 1.6 ratio 3/8 rocker stud
5.7'' connecting rods
Edelbrock RPM air gap intake manifold
hooker headers
Big question- Should I go carburated with a holler double pumper or 454 tbi with 454 injectors (95 silverado z71) ?
Msd Distributor

My quest is to build nice hp numbers with the torque number close or more than 500 ft lb at a nice low rpm steady increase (heavy 4x4 truck)

If I could get a little help as to where to turn the first wrench, I can start building a motor I been wanting for a long time, I just want everything laid out in front of me before I begin and understand everything and how to do everything CORRECTLY.

There are sooooooo many threads about parts for 383s on this site. It's getting really tiresome. Use the search feature on the home page and i'm sure you'll find what you're looking for. And by the way, you can't use big block parts on a small block engine...

You will have to use a throttle body spacer so the butterfly's wouldn't hit the intake.IIRC. And you will have to redo the stuff in the ECU chip to tune it also. You should be able to re-use your sensors from the 350 though. I don't remember what the circumference will be with the 454 tbi on the 350. Seems like it's pretty large though. I don't know about the whole set-up though seems you will have to turn the fuel way down and it still might be to lean. I don't know for sure .JMO keep us posted with how it turns out if you decide to go with the 454 tbi. I really like a carburated engine but when you get into the injection that's nice to. Just not sure if you can get all the bugs out of it or not but if you do it should be pretty sweet. JMO I do know people have done it with goodluck and some not so good.

X a bigillion!!

type in building a 383 on the search feature and you will find more reading then you will wanna do. There isn't a 383 combo that hasn't been talked about on this site

Pay careful attention to piston selection. I noticed you didn't put a part number down. If you're building a street motor, aim for around 9.5 - 10:1 compression. So you'll need around a 12cc to 18cc piston. Get a dish piston with a D cup for better detonation resistance. Research dynamic compression ratio. Also, search "quench" and "squish". It'll play a key factor as to whether or not your engine will run on 87-93 octane gas. If you have questions afterwards, feel free to ask.

Also, look into getting BoxWrench's basic engine building DVD. It's well worth the $25. They have many sample videos on youtube.
