Milling your heads ten thou will decrease the chamber of a 76 cc SBC head by less than 2 cc. Or from 8.3 to 8.4.jessie355 said:what about haveing the stock 350 heads that are 76 cc milled 10 thousants what would that bring my compretion too need some help please pistons are stock 350 dished 4 valve relief
So none of these heads are 2.02's?jessie355 said:882 are all stock i was thinkin of getting the stock 350 heads that are993 i do believe miled down 10 thousands
Your pistons could have anything from .060" to 0.100" dish, IIRC. You don't know what the piston to deck measurement is, nor the exact chamber sizes of the heads, so guessing the CR is a crap shoot. I'd guess about 8.4 for the 882/993 heads, and maybe as much as 9.8 w/the305 heads depending on the cast number.jessie355 said:well ill start over have a 350 2 bolt main stock bore with stock pistons that have a dish with 4 valve reliefs and a stock aluminum intake with a 600 holley have headers with 2 3/4 in pipes with 2 chamber flows and a lunati bm2 cam 292 292 480 480 lift cam and a 350 turbo trans what kinda horse power u think ill get out of this set up with the 58cc ho 305 heads that have the straight down center intake bolts the stock 350 heads993s and the 882 with 202 160 valves
