4.10's in the dana and a 4 speed

i plan to hit the dyno at some point. any guesses to the #'s?

im also considering a doublepumper. in the near future i wanna get the heads ported and get new tti headers. prolly a different cam after the heads get ported. so i would have to get a carb that would work on the motor now and after the upgrades.

Sounds like a well thought out build... should be loads of fun. How does it drive?

Welcome to the board.

thank you, a buddy from another board pretty much picked out everything so i cant take credit. she runs real good but im having issues with the secondaries. they appear to be not opening at all after doing the paper clip trick. i might just replace the diaphram and see if that changes anything. that or get a doublepumper haha.

Yeah, don't be afraid of sticking a 850 double pumper on it. It will like it.

Welcome. My old 440 build was close to yours but I used ported 906 heads. I would think you will be in the 475 hp area at the flywheel. Good luck. Ron

Welcome.....Sounds like a nice strong build and I would hope for close to 500hp and tq...............

should run good. The Proform actually makes your carb flow 823cfm. And don't worry anout those 1 3/4" headers, I run 11.30's w/ them. go have some fun.

what do you guys think she would run in the 1/4? i think im gonna pick up that proform doublepumper.

Cam is a bit small for your gear IMO but should have tons of mid range and rpm quick.

Headers are fine for a street car.

Porting the heads would'nt hurt.

I would get the carb dialed in first.

Then change one thing at a time so you know what works/doesent work.

A 750 is fine for your cam and headflow.With ported heads and/or one size larger cam I might consider an 850 DP with a 4 speed and 4.11 gears.

You get it dailed in it can run mid 11's. I used the 1-3/4 headers on my old 440 and it ran 11.49 @ 116 best. They worked fine for my street car with mild heads. I went to 2" with this eng but I use EZ heads on this eng. You will be fine with the 1-3/4. Ron
