Mr70,

Of the 3 L-89 70 Chevelles you mention, would you happen to have information concerning the possibility of them being produced early in the model run or not?

92646,

The 11:1 TRW piston worked just fine without modification in my motor. However, it seems a .040 head gasket was used as we weren't sure about how much compression we could run on pump gas with the alum. heads? As for the domes, I don't think it would have been an issue with a thinner head gasket?
