390 stroker build

I was talking dynamic comp. not static :D. Dynamic takes into account cam timing also. About the max dynamic you can run on pump gas is around 8.75 to 1 and you have to be really careful with ignition timing at that. I'm sure you will want to be in the 9 to 10 range for static compression.

Also, i was just looking at pistons and there not as widely available as the 340/360 based strokers. I did see the KB/Icon forged, but? Have you talked to anyone, shop, about it yet? Or have you looked into rotating assemblies? Just curious what you'll end up using.
Most likely will buy a rotating assembly.I have a builder I've known for years.Old school hobby builder/drag racer.. Only Mopar of course! lol..
