If we don't have accurate numbers we are wasting our time trying to help you. Take it to the track on the next race get some realistic numbers and we will be able to help you with your combinations. If your motor is putting out 425hp it should run in the 12's if its putting out 245hp you'll be lucky to be in the 14's. There's alot of difference in what you need to run, between the those two numbers.

Next race Penwell Raceway May 23, gates open at 10:00, this will eliminate all the bullshit. My slightly experienced guess will be 15.20 @ 88MPH.

IF YOUR GOING TO RUN IT ON THE STREET I WOULD GO WITH A 10 1/2" WITH 3000 STALL... OR POSSIBLY A 3500 STALL IF YOU HAVE A SMALLER OR LIGHT CHASSIS..

What a freaken punk you are onedragracer, what does 425hp have to do with ET in a 4800lbs truck anyway? It is totally possible to make 425 hp with a 383 sbc, and be a mild motor. I had the same situation happen to me when a punk claimed that a 406 (pump gas flat tappet) I built would never run inthe 6sec range in the 1/8th. He and his little boys showed up to see it run because I claimed it should run solid in the 6 sec. Well the first few runs it didnt and they all carried on and laughed. I found a small problem with number seven rocker and repaired it (it backed off adjustment) and it proceded to run a 6:76. They were all gone before I got back to the trailer! They thought they knew everything to! I figure they saved themselves a thrashing from me. I guess the moral of the story is keep your flap shut and you may learn something! Well if your pride lets you anyway.

onedragracer

I don't no who's flap your talking about assholy, but when You don't know what or who your talking about keep your assholy flap shut. If you want a thrashing be a penwell raceway in odessa tx june 20, 2009 I will show you what a thrashing and a asswhooping is all about.

onedragracer

By the way assholy, why don't you try running in 6500' DA then you can run your mouth. Living in Georgia, like you do, the mountains up north aren't that high.
By the way assholy I'm from Reynolds Georgia, tell me where you live assholy.
