I run 24 pound injectors and I have a 396. You can run 30's also. I like to run smaller injectors and run them harder. My tuning has become easier with the smaller injectors. You also did not mention what year your car is. That will tell us weather you have speed density or MAF
FMS 24# on mine, ran rich on 30# Accels before I went to 24#'ers. I would think 26# would be just about right. A lot has to do with your chip programming, make it's done right for the injectors you use. I think SVO are rated at 38 or 39 psi, I run about 42 psi. If you don't have one get a Adj fuel press reg. Holley is best.
30 # FMS injectors with an Ed Wright chip. Still waiting for an Agostino Racing dyno tune , coming early Sept. I'm currently running the fuel @ 50 p.s.i. My mechanic tried to turn it down a tad, but said it wouldn't go any lower. Possible bad AFPR?
