Oh yeah, forgot- someone mentioned ethanol in the gas. That's a good thing, 'cause E85 has a 104-105 octane rating and might be the way for you to run big squeeze where you are. It requires some specialized fuel system pieces, but nothing major. One more variable!

Todd, is it my eyes or is the oil ring a bit blue on that #2 slug. Blue means heat- is the bore scuffed at all? You know, the purists will scream, but if you could source a piston of the same configuration and near weight, you could balance it to the same weight as the Venolia slug and stick'er in, manufacturer be damned! The engine can't read the name on the box. Check cylinder taper while you've got the pistons out. Good thing you found this $hite out now, rather than at 6000rpm, later. I'd roll the rings off a few and check end gap while I was at it, as well, mind the orientation of the rings when you remove them. Ah, what fun, eh?

The FUN part is sourcing the dang piston. I haven't built a lot of motors, maybe a dozen or so and that's stretched out over 30 years. This is my first stroker and I'm finding out how much I don't know. Never done a roller cam before either, but that's pretty strait forward.
Assembling the right combination of parts is what's tough.

E-85 is 104 octane :clueless: Can you imagine the looks you'd get at the gas station? :roflsmiley: A Bad A$$ Challenger rolling in to the E-85 pump!
