Customer q:

I can't decide between #835171 and #835162. I have a 454 big block over 0.020 with 30cc pistons, a .625/.639 hydraulic roller cam and 502 rectangle port heads. Which intake would work best? Single carb or dual carb? And what size carb should I use? I have an 800cfm holley carb. If i went dual, would I use 2 600 cfms? Thanks


ac = Yes

drivewheel = 2WD

engine = 4.6 v8

fuel = fuel inj

make = ford

model = mustang gt

pwrbrk = Yes

pwrstr = Yes

trans = auto

year = 2001


I would suggest a single carb manifold for the combination. The 800 you have currently will work well. If you simply want the look of dual carbs, you can do this. I would suggest using 450 cfm carbs. Thanks for choosing JEGS and have a good day.
