331 Stroker, What piston to use

lucheski · 02-08-2005, 03:41 PM

I just got a 331 Stroker Crank.

Can I use a standard 302 Piston with a 3.25" stroke crank and 5.4" rods in a stock block? I want to get my final compression to about 11.5:1, without spending 700bucks on pistons. Can this be done in the 300-450range with a hypereutectic piston?

All suggestions welcome, thanks

That ain't gonna work. With the parts you have listed there, you need a piston with a compression height of 1.175" Stock 302 pistons aren't gonna work. Keith Black, Probe, are gonna be your best bet for reasonable priced hypers.

Good Luck!
