CC of SE pistons

[Jack Klarich]

Unless there's a new piston on the market dolt is correct. The 88 needs to be bored to a 95 for the 10:1 pistons to work.

Nope see the chart I posted from Weisco in post #5

There is a 10.5:1 Wiseco for the 88" motor but it has a 19.6cc dome. One would have to be careful with head work that included larger valves and higher lift cams and cam profile in general with that piston. Certainly doable but one of those "measure twice, cut once" situations.

The 88" will have to be bored to use the piston the OP has in hand, assuming that the pin height is correct for the 4" stroke and I believe it is.

Good info dolt

Or bore to 98" and use the appropriate Wiseco (3.937" bore) from the table in the link Jack previously posted. 3TQ/HP, at least, for free........

HD doesn't make a .030" over bore piston; .010" and they used to offer a .020" back in the day; not .010" only.
