That is a great running and looking car. I would love to see some track video. As for traction, the first thing I notice is how high the car sits in the rear. Weight transfer is a huge part of the equation. If you could get that back end down and get a flatter stance, you should reap some immediate improvement not only in weight transfer but suspension geometry.
I gain about 10 hp with the cut outs open, I'm still running the edelbrock heads, rearend of the car is not as high now, as in the pics, still need to work on weight transfer. My goal was to have a nice street car that runs in the mid 11's :3gears:
Very nice car! I pulled a 1.499 60' at Englishtown on 28.5 x 9 Pheonix slicks. 90/10 lakewood shocks up front, h&r rear suspension with anti roll bar. Previous set up was 90/10s, south side bars, air bag with 11 lbs. averaged 1.60 60 ft. Tuna
Good job!! I've looked for you @ Muncie since the night we were both there, glad to see you are still working your car out. Hope to see you @ BG. Randy:3gears:
Craig, here is the run just before my best. 60 1.678 330 4.828 1/8 7.447 mph 93.88 1000 9.717 1/4 11.643 mph 117.05 Tuna, Thanks for your suspension specs, I think I need to try a taller tire. Randy, Shoot me a PM next time that you go to munice maybe we can race together. I will let you if I'm going to BG. Hey, what tire size are you running on the rear?
I'll let you know if I can make it back this year. I run 275/60/15 drag radials and 28x11.50x15 bias ply tires. The ones you saw that night were the 28x11.50's, they have 9" wide tread and they are Mickey Thompson ET Streets. Randy

Measure the rear lower control arms at each end. If the front is more than 1" higher than the rear, you have more traction to gain by going lower unless you are getting perfect traction already. A really soft front end is very helpful. If you install Southside type lower control arms that drop in the rear, the original arms must be lowered first. then install the dropped arms. This lowering assures that the upper arms have a good downward angle so you have a good IC and all this will work. HR bar is a good traction aid too, of course. TUNA said the HR bar was better than southside bars by .10 !
Thanks Gary for the info, I have my engine out right now for some work, but once it is back I plan on working on the suspenion. Thanks for your post on traction, great info!!!!
