Sooooo, you’re saying there was a time when it was.....”fun”?
From a strictly “flow” standpoint..... the ootb 265cc SM BB heads flow enough to go 10’s....... but that doesn’t mean a little tweaking wouldn’t help.
If you get the weight down, 10’s isn’t hard at all.
Under 3300 race weight and 500hp, a good converter, and some hook.
