yeah, zealworks is the only one that is correct, but it doesnt matter, because the rest you have to figure piston to top of deck clearance manually.

i dont know many specs on the B series to check the calculator for errors, but everything seems right.

how i figured it was took stock c1 specs and adjusted the piston compressed height to that of your aftermarket piston, then adjusted the dome height to get 9.0:1, which made it -4.0 cc dome. then just swapped the block and rods to that of the LS, and came out w/ the calculations.

damn! thats strange, it seems with all the shavings thats been done to the head and the block I would be at 11.5.1 but instead its lower
so now with the new head gasket I should be at 7.0.1 or something in that range, I suck at math so thats hard

got do the cc adjustment before factoring in the compression height.

z1guy

it will still work out to the same thing. specs on the piston are as i said above, cant be differant, unless CP doesnt know the correct specs. i wish manufacturers would just list the specs instead of claiimed compression ratio.

I came up with 9.0.1 I figured out the dome cc off arias pistons website, with the help of a friend

compression height= 29.9974
dome cc= -12
headgasket thickness = 0.001 thats after subtracting .040 and .010 from .051 for the head milling and decking
b18a rods
b18c pistons

on the zealworks calculator w/ the milled block and head and the thicker gasket 9.97:1.

I look at it like this, even if we are off a little, as long as its below 10 compression I feel better.

z1guy

well, as long as you use that .051 headgasket it should be.
