I was wondering if the 8.5: 1 compression ratio listed in stats for the 87 - up 460's is achieved with pistons or do the 87 up 460's have smaller cc heads?

Can these pistons as stock replacements be used to replace the 8:1 pistons in the older 460's for a mild compression upgrade?

 

have you looked up part #'s and compared between the years? That will tell you what you need to know as far as which one is affecting CR.

Good info on that kb-piston site. It appears the pistons are responsible for the slight compression increase.

This might be a way to get a little compression boost and keep your engine happy on 87 octane.

Didn't know if anyone had went this route or not.
