It seems that every piston Ive found in summit and jegs for the 383 had a floating wrist pin. Im lookin for one thats press in, and wud give me roughly 10-10.5:1 with 64cc heads. forged/cast/hyper^%&$, whatever, Ill take what I can get. Id definitely like to stay away from cast, but whatever.

Main ones I was lookin at were Wiseco and Sealed Power, they seem to have pretty good prices.

 

just about any that'll float will also be a press fit, whether the pin floats or presses is more a function of the rod, plus the pistion has to have the retention system for floating pins

 

Don't look in the Summit catalog, look at the piston manufacturers catalogs. I know just about every piston company makes them. Never use one source for you information, don't be the next CBS news.

 

Ill have to use that one

 

The pistons and pins are the same; it's a question of how the rod is prepped. You can put floating pistons and pins on rods that require pressing. You just don't have to use the Spirolox.
