I'm figuring out what fuel components I should run for the 347. My ultimate plans are for ~325rwhp N/A with possibility of a KB on the distant horizon. My compression is going to run high-9s. I'm going to use the stock fuel rails but I need to change the pump/regulator/injectors. Suggestions?

walbro 255, 30# (n/a), 42# (k/b), stock or kirban fpr, the k/b won't fit an adjustable pfr, at least mine didn't. even getting the stock one under there was a challenge

i would run a minimum of 30# injector or 42#

throw a 255 in the tank with an in line pump

i have an areomotive fpr and it's a nice piece, but i think any aftermarket adjustible will do

I have 30's on my 347 now and with the blower I had 42's. I've used the same 255LPH in tank pump with both set ups.

Why does he need an FPR? The stock one is fine. Get the right size injectors (30#) and hammer out the correct tune. Working an FPR on our EEC is way too much of a pain, IMO. Use the search function for tons of reading on it.

You might want to think about just getting 42s and an LMAF right off the bat. When you strap on the blower, just pay for another blower specific tune. You might as well just do it once and do it right. A competent tuner will have you running fine NA on 42s.

I wouldnt say he needed a FPR i had one from back in the day before my TwEEcer to adjust fuel and what not. So i just set it at 39psi and leave it now. I have no plans on going blower any time in the next several years so i went with 30#ers because i they are enough. But if i was you and going blower soon after i would like Adam said just get 42#ers and an LMAF and just buy it once.
