I think it will be 4.90"s to 5.0's
Maybe some mid to high 80's depending how good the heads are.

4.80s hardtail with a front suspension, car cant weigh a lot.

I do think a good change later on is a set of dart 355 heads for it.

Thanks for the replies, I am hoping for 4.90's. I agree with the head change, the Merlin's look good though, John at APD done a valve job, and some bowl blend work on the heads a couple of weeks ago and he said they should have no problem making 850-875. I am planning to switch to a set of Head Hunters and make it a 582 if everything works out with it this summer. Thanks Allen

Off to London Dragway today, I will post results tonight when I get home. I am going to say 4.95, it is supposed to be 85 degrees here today and this is only the second weekend on the race track, so it may not be up to par yet....

It ran [email protected]
1.08 5
3.14 8
4.88 0
141.00

Car ran great, no issues at all. However it was really inconsistant. Ran within 3 hundreths every pass, but was up and down .03. It was all in 60ft/330. It only moved .004 from 330 to 1/8 mile all day.

Had a tire issue with my C07 15x33's (screw in 1 tire) so I put a set of 15x55 D05's on and I don't think it likes them. Car is dead hooked about 20ft and then shakes the hell out of them for another 20 ft. Track was good as no one else was having problems.
