Building specs

[MORFF]

Ok guys need your help my 383 I am in the process of taring apart to rebuild it. Found this site www.kmjent.com good prices. My 383 was a 2 barrel 383. I want to make it a factory 4 barrel 383. Can you guys tell me what cam I need what pistons I need. I am looking for like 375 to 400 hp with headers. I would like to use my 906 heads if possible.And if there is any good engine shops in Connecticut I want them to clean inspect bore min over hopfully.010 change bearings and freeze plugs. Thanks allot guys.

yep, 906 heads will work for 400hp

KB162 Pistons work well....so does the CompCams 274H for that power.
The "trick" is to optimize Head Chamber CC or Block decking, sometimes both, to realize an actual 9.3 to 9.5:1 Compression Ratio.
After that....
it's just intake & carb, yada, yada, last one I did Dyno'd at 430HP and 440Trq at the Flywheel with some pretty mild porting, plenty enough to motivate a  , and was VERY streetable.
