Re: Inexpensive 350 Build
NEW BEST at the slow track @ 1700 DA
1.43 60 foot
6.87 660 foot
10.89 @ 120.2xxx MPH
The fast track is .005 quicker and 1.2. MPH faster in the 660, that means high 10.70s @ 122 in 300-500 DA, couldn't be happier! Seem to be stuck @ 1.43 60 @ the slow track.

Re: 496 Drag Test REDO.............
Nice job . Can you FedEx some of that 2000 da air up to central states.lol. By time season starts in Midwest it will suck.

Re: 496 Drag Test REDO.............
