How much compression?
I am thinking about buying a fresh 408 stroker from a guy. He said the following
aluminum 6.0 bored 30 over, eagle 4.000 crank, 6.125 howards rods, and diamond +10 pistons.
goals are street truck (s10)
Currently stock ls1 on 150 shot
Want to put this 408 together with the 799 heads I got and a 228/232 cam and two kits probably 250 shot.
what compression ratio am I looking at?
what would yall do?
h/c/i lts and nitrous.

Diamond sells forged Nitrous LS pistons.
The 408 pistons with a 10cc dome designed for LS6 heads are part number 11565.
These 10cc pistons with a 64cc chamber (799/243 heads) puts compression around 13.6:1.
With 317 or LS3 heads, compression is around 12.5:1.

I thought it was only the la1 block that couldnt be bored much. Should I be concerned about sleeve thickness?
stock thickness fel pro gasket is what i've got.
the motor is in pieces new in box, just needs to be put together.
