I think the crankshaft HP will be more in the 440-450 range. The combination sounds good but your real HP limiting factor is the cubic inches. The other issue I see will be traction. That considered, I would say 7.90 - 8.20, in the 8th. Theoretically, there is more e.t. in that HP. I'm just thinking that without slicks you will not see it...

Do yourself a favor and keep the max RPM's and shift point more in the 6800 or so range. I don't think there will be a difference in 6800 and 7200, but your engine will last longer at 6800.

My opinion is worth just what you paid for it. :)

Good Luck & Great Racing ! ! !

just gonna be ran on the street mostly anyway not gonna see 7000 alot like a all out drag car would it's only gonna see that when i need to shut someone up :) as far as c.i i was gonna go 383 but my machinist said it's a pain in the a$$ to notch the block and it really wouldn't be worth the hassle if it was just gonna be a street car for the most part, the sportsman pros are suposed to have a wrinkle wall design and be a drag compund tire but we will see how it hooks up i guess

thanks

The best estimate for any Drag Car's performance comes in the first pass that you make clear through the quarter . .

Anything before it is a wild assed guess and anything after it is hopeful thinking . .

Heheheheheheheheheh . . . . .

Its not that hard to clearence the block and in my opinion well worth the extra money for the power gain and flatter torque curve.

yeah im just gonna go 406 i forgot all about the 400 block i had out back

Just guess... in a body @ 3600-3700lbs, @450HP w/488's & 4000 stall you should be able to run 15 seconds or less. :lol: :lol: :lol: :lol: :lol:

Nah seriously, you will be a serious threat on the street from light to light. Not one kid with a FART CAN & A LAP-TOP will touch you... go get em.
