I have a guy that wants to sell me wiseco K394A3 pistons and a 4.00 crank and i looked up the part number and others are saying with these pistons they are getting around 11:1 compression with 66cc heads even though they are -8cc dish.

my problem is im wanting to build a boosted engine without high compression.. . im running l92 heads. could i still run these and be ok?

thanks

anyone???

 

Those pistons with a GM MLS gasket and 66cc chambers will net you about 10.8:1 static (depending on how far pistons are in or out of the hole).
