Just looked up specs, 046 52mm bore, 36mm stroke
066 is 54mm bore, 40mm stroke

So if it was made to fit, looks like it would be like an oem bigbore for the 460

Not sure how thick the base is but you would need almost .080 off the base to get back to factory squish with a gasket, unless the 066 or another piston has a taller crown height.

Certainly not a practical conversion, IMHO.

didnt think so.took off the cylinder to make sure he wasnt bsing.sure nuff 1122 cylinder 1128 rod number.no machine work.i think a little methamphetamine is involved though.

Anything is possible with willpower and a dremel

Correct me if I'm wrong;
The extra 4mm of stroke would differentiate the big bore 460 from the stock 660, and the only way to get more stroke is with a bigger crank, so don't we end up back at a 660 case?

You're going to need to post some photos of this hybrid.

1122 cylinder has decomp.ill measure shortly to make sure

 

[Definitive Dave]

meth+dremel+willpower = 064 cylinder with decomp
