First post... Woot..
Anyways i'm in the middle of my 347 build, have most of the short block assembled (Have yet to buy cam and heads). I measured the piston to deck height tonight and the pistons are sitting at about .017 below the deck.
Looking for around 10.2:1 - 10.5:1 compression.
Piston valve relief is -11cc., I did not have the deck milled. I was going to get afr 185 58cc heads. But after calculating static compression i would be sitting at about 9.78 ish static compression, this is with using a .040 thick head gasket.
I would prefer not to have brand new heads milled....
Another work around i thought of would be to use:
Trick Flow 11R 190 56cc heads
.032 thick head gasket
This would put me right at 10.2:1
Only problem with this is i'm worried about valve to piston clearance. Was going to get an off the self cam which would be the Compcams XE282HR..
Just in case if its asked, engine is going in my 93 fox coupe (Getting painted), going to be mostly used on the street, hp looking for seems too be a lot a lot of peoples goals which would be around 400rwhp...

^^^^^ stoker kit i bought and installed^^^^
Just looking for ways that i could achieve the compression i'm looking for. Or hoping the workaround would work
