I have the edelbrock 70070 n20o kit that i user with my pro flo EFI. The jetting is for 100 and 150 hp and there is nothing for 200 hp jetting. I know the fuel pump they supply with the pro flo kit is for 600 hp total on motor/pwr adder, but i have a high performance fuel system, etc. I called edelbrock and they said the plate wont support a 200 shot flow?? I obviously am pulling out the respective timing to prevent detonation. I would like to remain on pump gas (93 sunoco).

the motor specs are:
355 with 10.3:1 dart block
race rite 200 cc brodix heads
comp cams solid roller 4/7 swap 252/[email protected] .624/.650 lift
full exhaust, etc.

the jetting edelbrock gives:
100 hp - 59/39 n/f
150hp - 72/50 n/f
the kit is a 4an line with performer rpm nitrous and fuel solenoids. if anyone can give me suggestions for 175 or 200 hp jets id appreciate it. thank you

Joe

Unless Edelbrock jet numbers are a lot different than NOS jet numbers, those numbers look a little strange. Are those numbers based on a high pressure EFI fuel system? I would call Steve Johnson if I were you, he's an Edelbrock guy.
