Thanks guys. Didn't spend big bucks Ray? I think my previous best was an 11.33 @ 119.06 mph in good evening air. In the heat of the day would normally run 11.40's - 11.50's @ 118 - 116 mph depending on air. My previous best 60' was also 1.55 seconds but in really good conditions, the air on the weekend wasn't the best, not sure what the DA was but other guys were off. The changes were, Holley HP 150 pump, remove air doors in carbs, 0.080 sec jets, a little more timing and short shifting @ 5600 rpm. I previously ran jetting tune (2 x 600 eddys)# 21 in the eddy book with .086 jetts in the rear. Same jetting in the front but with the .080's in the secondary's now. Previous fuel system was stock 3/8" pick up with -6 / 3/8" line down to a Carter black 100 gph pump mounted aft, then 3/8" line forward into a cool can in the engine bay. From the cool can 3/8" line into a return reg with 5/16" fuel return back to tank. From the reg was also 2 x 3/8" lines into carbs. After checking the timing for the first time in a long time found that total was only around 28 deg, should have been 36 deg. This would explain why over the months the car slowly started to run warmer, used more fuel and became slower at the track. I think the dizzie clamp nut wasn't tight enough

Bumped timing up to 38 deg total. Being a test and tune I also wanted to play with shift rpm and found that 5600 rpm was the sweet spot after previously shifting at 6000 rpm. New trap speed over the 1/4 is now approx 6200 rpm from previous 5800 - 6000 rpm.
Any pix of your car Dan?
