motor is tsp 408 ci, prc 2.5 ls6 heads, 232/240 .595/.609, 115LSA, 112ICL cam. fueling is racetronix 255 pump and hot wire, 42lb injectors.

my car is not going to be, by any means, a "max effort" car any more, so i intend on going with a d1sc setup, and hit it with a little bit of boost, and put a t56 back in it and have a healthy street car. what are your thoughts on my current fuel set up, but with a larger injector, like a 60lb or 80lb, and keeping the pump. think i could see 8-10 psi with it? any one else running a similar setup?


i ran a search, but its hard to single out bigger cube motors, low boost, and 255 pump results. thanks in advance guys.

Twin pumps for sure, 80# injectors

Yep twins and 80# injectors. That single and 42s would be lucky to make 550rwhp

also that single pump even with a bigger injectors isn't going to support more than 550 either

You can get away with 60s but why bother unless you already have them. Have to have a twin setup for sure
