my fuel system is 1/2 alum. line from 8gal. cell all to holley blue pump then to holley reg. and a fuel filter then to the carb inlet line..the press. gauge set on 7.5 when i go higher it seems to be realy rich but now only thing i changed was the carb and spacer and like i said with the 750 aed/ho it pulls all the way though with no problem,but with the 950hp it will pull just til the 1/8 mark and stat to bust up like it needs new springs or something...i just dont know where to start......but i had my best time with the 950hp..also with the 950 he buddy that was at the line with me said he could hear the car blow the tire off when i leave.... i have a vid. of the car leaveing on the 1st pass and then the 3rd ill try to post not sure if i can but i need to get on this fuel deal...i know the car has way more in it if i work it out.....even had chevy guys talking about how good it should run if i get it right. so any help or ideas would be great
