My brother doesnt want to post this on a local site and Im all jacked up about it so Im going to put it on here. He never gets on here any more. lol, Anyway. Im going to have to go thru a little history and it going to be a little long. Sorry, try to bare with me. For thoes that dont know. Its a 71 chevelle with a 505 bbc, glide with a gear vendor. It had a decent set up. would run a 6.7 on motor and 6.1 on the gas. All on pump gas. When we started spraying the car we tried a tighter converter. It didnt really help and it killed it on motor so we put the old converter back in it. Well when we did it pulled the input shaft out of the trans. I just pushed it back in. Didnt know you could do that. It ruined the trans and the conveter. So we had to put the tight converter back in it. Then it droped a valve and ruined the heads. They were iron oval port heads. Got some dart pro 345's. picked it up a little but not much. Then one of the lifters wheels went out in it. "solid roller". So he went thru the whole engine. Put a lot bigger cam in it. Cam did not like the tight converter. Would only run a 7.1 with a 1.8 to a high 1.7 60. at 102. Its only stalling to 2500. it need a 4500. Well we just recentil borrowed a converter from a friend.So we could send the one we had off to get restalled. He had never run it. it came in a car he bought. was told it would stall to about 3500 with a 468. We took it to the track last weekend. We drove it across town. drove back home to pick up my car. About a one hour trip. Then drove both cars to the track. Another 45 mins. Chevelle had 87 octain gas in the tank. It only has 9.2 to 1 comp. It went a 6.62 at 105 with a 1.58 60. When the car ran a 6.7 it would get a 1.48 60. If we can get it to 60 like that again I can see it going a 6.4. Thats with 87 all motor.

Camaro ran a 8.24. it has long tubes, crappy loud "loud mouth exhaust" 3.90 gears and a slipping trans. lol

I'd try what this guy ^ said and see how that affects the 60ft.

Those are some good times.

6.6x's at 105 all motor on 87 octane is pretty impressive. Especially for a car capable of driving to and from the track....

have yall tried overdriving 1st with the gear vendor during a pass?

Ya. we have tryed over driving 1st. If you do it right it might pick up half a tenth. Not really worth it. Engine makes to much torque to make it worth while. Id imagine on a high reving small block it would be great. We use it roll racing sometimes.
