what should my compression be, LS block / head wiesco pistons
I've search around but i'm just not sure if my math is right, And i'm sure some of you have this inof right off the top of your heads. Current set up.
B18b1 block: Stock bore
B181b head
Wiesco pistons: k542m81, 81mm bore, 3.504 stroke, 1.175 comp ht.
Using stock honda head gasket.
Rods: Eagle H-beams (esp)
I tried to use the calulator above but, when it asks for dome cc, weisco lists FT -4? What the hell is that?
Ran a compession test and came out 170-180 across the board. Is this in the right range?
Motor only has 2000 miles on it, Not sure if my gauge is right because at first is wasn't holding the pressure and was bleeding off and a slow steady rate. Anyhelp would be great. Just wanna make sure this bitch is still healthy because 6psi just isn't cutting ti anymore and i wanna go at least 10 if not 15 by months end.

Could the FT -4 stand for 4mm below deck height? When you ran your compression check, did you try pouring a little oil into the cylinders and then re-checking? If it stops bleeding off, then your rings are probably on their way out, or were never properly seated.
