New Best on Friday Night!

ok guys, just wanted to update on my progress or nonpregress. I am losing time down the track so I recently installed a 3/8 sending unit/pickup and 3/8 line to the pump then the carb. That gave me about 9lbs of fuel pressure at idle so I then installed a fuel pressure regulator.

Hoping this might solve my problems I went to the 1/8 mile track last night. It didn't. Car ran the same. Excellent 60 ft times but still doesn't seem to live up to its potential on the big end. I think I may try to run less timing next time out. Could it be that this thing is just a beast down low? Really, 7.83 in the 1/8th isn't shabby for my mild budget combo I just keep chasing more because of my awesome 60ft times. Any thoughts are appreciated
