70 dart 470 ci drag car build.

I did at sometime. Got tired of talking about. So I surf and live vicariously thru others efforts. Lol. But essentially 451 12.4:1 comp on E-85 metered single 1050 (4150) carb. B1/BS Heads. Cam is nothing too hot at .585 lift mech flat tappet.

Heads have more porting room. And cam could be improved. But it's new and functional. (Not comfortable pulling components that are working fine. Knowing I'm perfectly capable of screwing up something that doesn't need fixing. Lol.)

Sweet id love to have a set of B1 heads.
yeah I don't mind tearing stuff up to go for a little more, but I just need to see what this engine will do, with slightly bigger than standard ports and what I call a streetable cam, the lift is okay @.660-.674 but the duration is easily 10-12 less than it should have
