I don’t mean to poop in your cheerios but that’s a 260-280hp combo at best. And unless you are very good (read: precise) at setting up the valvetrain there’s no way it’s going to spin “7000+”, and there’d be no reason to spin it that high anyway because with a 216@050 cam on 318 inches it’ll be all done making power well before 6200. Build it, tune it, and stick it on a dyno, if I’m wrong I will gladly accept that, but I don’t think I am.
