383/489 Stroker

^ how much lash?

I think this cam will be a "little on the small side", if you want "sound"(which I think is mostly for all show, no-go trailer park trash:mad:), but it should be a very nice cam to actually drive and live with.

I'd go with a smaller bore gasket set, if possible. A FP-1009 is 4.410, and there's a bunch of MLS gaskets from Cometic/Mopar/Mr Gasket that have bores between 4.350 and 4.440 that "should" work very well, if a bit more $.

With that 4.25 stroke, I don't think a bunch of rpm is required or even desirable. With that gear and tire, 65mph is about 3100rpm. Your opinion is the only one that matters whether that's good, bad or indifferent.

I ran some generic #'s through pipemax, based on what I know/assume about the cam and heads and here's what I got: (using street headers w/muffler)

Expected HP: 585 (avg) 565(low est)
Expected torque: 618 (avg) 595 (low est)
Operating rpm of components: 3500-5500
Octane req: 99-100 (R+M/2)
Max rod tension: 2420 G (multiple this by the reciprocating mass and this is what your rod bolts need to handle)

Opinion: I'd go to a 3.55 rear end gear or a taller tire. But I think this would be a very "fun" engine with **** tons of torque, and unless you're on a prepped track, you are going to be traction limited all the time. S/F....Ken M
