I went to the strip yesterday and I am pleased with my results. My set up is 72 Skylark convertible, 350 .30 over, GS112, 10.25-1 pistons, headers, T/A intake with 750 quadrajet, making 368 hp with 400lbs torque. TH400 S/P 3,000 high stall. 3.08 posi. Flowmaster 2 1/2" exhaust with 30 series mufflers. 295/50 rear tires All times are in street trim. My first run was with my stock intake and a pretty soft launch to avoid frying my tires. 14.10 at 95.47, 60ft 2.022, 1/8 mile9.009 at 77.05mph I was pleased at this first run. I made a one more run to get a base time. I then changed my cast iron intake to the T/A. First run 14.152 at 95.39 mph. 2.047 60' time Second run 14.295 at 93.4 2.031 60' time My next three runs I changed my timing back and forth running a little slower due to getting a little warmer out 82 degrees my times were 14.484, 14.467,14.432. I then entered the bracket races and I dialed in a 14.45 figuring I can always put the brakes on! The car sat about 30 minutes bfore my next race so was cooler. I was up against a carthat dialed in at 12.55. I had a great launch and was running strong and I was ahead by three car lengths so I hit the brakes and finished ahead of him. I thought I was in the second round until I saw my time slip, I ran a 14.076 at 93.13 with my brakes on!!!! I had a 1.999 60' time. I would have broken into the 13's had I not slammed on the brakes!!! As for the T/A vs stock I like the 40lbs difference but as far as performance goes they are almost identical! I feel that with slicks I would have been ran 13.9's and withopen headers would dip into the 13.7's. Not bad for a 350 Buick pushing a 3,800lb car!
Tim, What were your shift points on your runs? We're heading down to Rock Falls Sept 24th for a Musclecar Shootout day. I've never been there before, how's the track and how strict was tech? Are you going to the BBQ in Lakeville on Septh 10th? I plan on driving the California down! :3gears:
Shift points were 5,500-5,700rpm's. I left the car in second gear twice through the traps but that slowed me down a little. I am getting some slicks and exhaust cut outs for next time. I was planning on hitting Rock Falls on 9/10 but since that is the party I will plan on going the 24th same day as you. So I will see you on the 10th. The track is good, tech is no problem...He looked under my hood and around the car for maybe 10 seconds... I know I will be in the 13's without exhaust and wheel spin! Tim
I guess I found my answer here. I see here he had a 308 posi. I was wondering why it had stayed in the 14's I was running a 373 gear with about the same horse. Mine is reversed on torque and horse. 390 horse and 373 torque with my set up and I had run a best of 13.31 at 99mph. I had used a nice loose 3500 stall then, could foot brake it to 3000 rpm. Any changes take place since then on the car? It has been a while, I know it is still running it's a 350, "Strong as Bull":Brow:
