To hit 13's, you need 3.91,s or better or with the 3.73's a little more stall in the converter and sort out the weight transfer in the suspension.

Mr.Yuck Not enough dumb comments...yet Joined: Jan 2003 Posts: 24,562 Brookeville, Md	depends on a lot of things. Is the carb tuned well? Have you drag raced before? slicks? Take a box full of jets and your timing light to the track. I suggest starting with 78-84 w/ 31 squirters and a 6.5 PV. Set for best vacuum. Start your timing at 38* (no vacuum advance) @ 2400rpm. Bring the car up on the converter slighty then waffle it when the last yellow lights. Shift around 5400. If you have headers try 5600. Good luck and have fun. I ran 12.90's w/ less cam but a little more gear (3.91) and a little more stall (2600) and slicks. I'd think you should see mid 13's once you get it all sorted out. Don't get upset if you pull a high 14 out 1st few runs. Have fun. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!

SomeCarGuy I Live Here S Joined: Feb 2003 Posts: 10,209 Someplace you aren't	What? My 69 b body which is the same car as a 70 weighs 3620 w/ better than a half tank. 440 would add only a few pounds over my 383. I have maybe 75 pounds AT THE MOST in aluminum stuff weight savings. I also have a full spare and a jack at the 3620 weight. Power steering would add I think 46 pounds based on what others have figured on here. MA article said 90 vs. 12 so...

How much do YOU WEIGH? And my quotes are WITHOUT the driver from a "stripper" version to the "fully dressed" version. I weigh around 185. The car is was all stock steel, no fiberglass. I did not have the spare and jack in the car. I weighed it at the track, this was an "as raced" weight. I'm guessing after 4-6 passes it'd lose a few lbs of fuel weight. The car did have PS and A/C. The A/C box was in the car but the junk under the hood was removed.
