rebuilding an old school 383 conversion...

[joe dirt]

so i got my hands on a 72 camaro 4 bolt 010 block that was advertised as a healthy stroker with aluminum heads...it was just a long block when i got it....pulled the heads and found 030 4 valve relief flat tops....one cylinder had a bit of scarring....rest where just glazed...tur. it over and removed the pan to find its a 4 bolt! yay!......it has a factory 400 crank turned to 350 mains...factory 5.565 400 rods and i believe the pistons are 350...i didnt see any grinding on the skirts......so to get going...its going to need an overbore to 040....new pistons and rings...im thinking about using the 350 pistons with the short rods.....the heads are cheapo pro comp heads 64cc.......id like to keep the cr around 9.8:1 or 10;1.......i picked up this block for $300...so im cool with putting a few dollars in it...plan to run an xe284h cam with performer rpm air gap and 750 dp
this will be going into my 61 c10 with stock sm420 4speed and eaton 390 rea end untill i can get a 12bolt under it with 308 gears.....manual breaks and steering...so vacume not needed as much
what pistions and rings should i be buying to achieve my goals?...id like 400hp.....find a stock 400 dampner or a aftermarket one?.....same goes for the flywheel.....stock or aftermarket....

any input is appreciated....this will be my first build...thanks
