Let's put a mild 8.2:1 360 on the dyno.

Shame you didn't slam some magnum heads on that. I had an 8.2:1 360 with a kind of worn short block and that thing really ran. Probably 25-30 more hp than this. Still not too bad there.

Shame? I don't understand. I have Magnum heads and I wanted these on there. It goes in an '85 pickup where the owner blew up his 318.
