jetting BBC PSI D 540

anyone run a Chevy with a screw? what is your jetting?
i have 4 #75 in the blower. #64 in #8
blower just under 2:1,43 PSI boost

we have a sand car and use a 990 pump no high speed lean out, common for sand.

can not get #8 under 1250 degrees

 

what type of heads and what is the total area of fuel system

 

Going to need more pump than that
more like a 1200

 

we only race 300 feet. i get a 1.1 60 foot 2.97 ET in the sand best this year.

our clutch setting is much different also. i thought i would compare fuel setting from sand 300 feet to 1320 feet if anyone run a BBC. i have Dart 360's

what is the total area of fuel system? have no idea what them means, no fuel program, just EGT and Racepack data

Thanks, Tony
