Idea Parts for chevy 383

This will be the firsr engine iv built. Iv been lookin for some help on what are some good parts to use as of now i have kb dome pistons, scat 400 crank and scat 6" i beam rods. Iv looked at comp cams big moutha thumpr and i really like that cam but thats as far as iv got. Really need ideas on what heads to run. Kinda on a low scale budget but can spend a little bit.
Thanks for any info

It would be it would be nice to know what your plans are for this motor. Is it for the street or Strip? Really makes a difference. For example a street motor would not use dome pistons because the compression ratio would be to high. You need to get some reading material on 383 stroker motors before you purchase parts. Make a decision on the horsepower and torque you want. Another thing to consider is the car that you are installing this motor in. Rear, transmission, converter have to be able to hold up to the increased power. Good luck.

First I hope those dome pistons where meant for those 6.0" rods and not the 5.7" rods. They are not interchangeable. I would have advised getting the KB 18cc dished piston, which with a 64cc head will put you at about 9.5:1. Which for your power gaol is where you want to be. A flat top piston in a 383 with 64cc heads will put you around 11:1 and a domed piston will have you past 12:1 which pretty much won't run on pump gas without a ton of hassle. A 400hp 383 is easy, set of 180-200cc intake runner heads, hyd f/t cam with around 220-225 duration at .050, performer rpm intake, 650 cfm vac sec carb and a simple aftermarket HEI distributor.

You could start by taking your block to a machine shop to have it checked, cleaned, bored .030, decked, cam bearings replaced, new freeze plugs and screw-in plugs for the oil galleries. Then you could buy a rotating assembly from summit racing: Eagle Specialty Products B13404E030 - Eagle Street and Strip Rotating Assemblies - Overview - SummitRacing.com and a summit racing cam kit: Eagle Specialty Products B13404E030 - Eagle Street and Strip Rotating Assemblies - Overview - SummitRacing.com. You will have to decide on brand of 64cc heads, a performer rpm intake and a carburetor. The dyno on comp cams website says a setup like this would make 381.3 hp @ 5000 and 439.3 peak torque at 2500 rpms and recommend a 2000-3000 stall converter
