Good day, everyone. I am building a SBC 383 TPI for my '86 C4 automatic. I plan on using AFR 195 heads with 65cc chambers, SCAT rotating assembly with 6 inch rods and +7cc pistons. I need advice on a cam, street/strip, I guess. It will be my daily drive. What I want is when I'm coming out of a curve, I want to punch the pedal and take off like a rocket sled. I'm also looking around for an intake. Maybe larger diameter riser tubes or TPIS mini ram. With TPI, I know I give up some performance, but I keep my stock ECM.
Id suggest you calculate the potential static and dynamic compression on that 383,
use of the stock torque converter, injectors, ecm, and rear gear ratio ,
may all cause you issues with a new cam and higher compression.
with 65 cc combustion chambers, on a 383 that intends to run pump gas,
I think youll find its high compression and use of pump octane gas might be an issues
any of the guys who gave, you advice that suggested you do more research before spending cash,
GAVE you good advice, but ID suggest you consider swapping to a 3.07:1-3.73:1 REAR gear and 2800-3000 rpm stall converter,
before you swap to a significantly longer duration cam discuss with the cam suppliers that you chose to deal with
youll benefit by reading a few links and sub links here
dynamic vs static compression
its obvious some of the guys on this site need to understand the difference between static and dynamic compression ratios, and that's understandable as its a difficult concept to grasp at first. your engines tendency to get into detonation is the result of higher effective compression that the...

bits of 383 info
as too costs involved here's one SBC 383 builds partial cost list, which may help you remember some of the costs your more than likely over looking the fact is this engine building remains mostly well understood and known science, a teachable skill, (for anyone willing to learn what works with a...

Tools Needed For 383 Sbc or almost any engine Assembly
I’ve been picking up tools and engine components for my build a little at a time. Among what I’ve picked up so far are a couple of Starrett micrometers in sizes 0-1” and 2-3”. Other than a 4-5”, what sizes would be required to assemble a 383? Does anyone have a comprehensive list of tools needed...
