Hey bought a set if twins with a 62/71/14htt upper and a ht3b lower and was getting your guys info on fueling for them. I currently have 330 Bosch injectors and stock 131 Dvs. Am I going to need more fuel you think to get over 55 psi? Haven't installed them yet but want all your guru ideas and thoughts.Also have 18 degree timing Mack plug. Home grind 100 plate. Afc screwed full fuel. Arp studs. And 550 Kenny clutch to harness it. Thanks guys

 

i say at least 5x12s

 

191 delivery valves

 

i would go 5x14's with 181's...but ur 330's will work...i would go with some 181 dvs though

 

either or is better then stock

 

eh... Ill say 5x.014's, leaves room to grow. You could do some 5x..012's with some comp dvs but you will have to much fuel at that point possibly.

 

if your running a 62 over a ht3b go 5x14s no dvs or 5x12s with 191s
