Trying to decide if 60# injectors would be too big for my combo. My combo will be a s-trimmed(12-15#'s) 331, with ported TW heads, flowtech blower cam(dur 234/242 lift .577/.576), E-brock RPM, intake, AOD 3000 stall, 3.73's.

Right now I run 42's with smaller cam and stuff and have kept the RPM's below the stock limiter. Now with the new cam, the RPM range with move to around 6500..

Anyway think 60's will be too big???

In my opinion (I'm not blown, so possibly take this with a grain of salt), the 60lb injectors would be just fine. Running 12-15lbs, you're definitely aware that you don't want to skimp on your fuel system. Were it my combination, I'd feel comfortable in knowing that I had the reserve if necessary, and that I chose to err on the cautious side. Are 60s too big? Maybe, but a competent tuner should be able to make them work like they came from the factory. Finding a fuel pump to feed them could be a problem if you're sticking with an in-tank design.

Yea thats pretty much what I figured. I was wanting to run 55's but got an offer to trade my 42's & meter for 60's and matching meter. And if I do get the 60's I will swap up the fuel system to match, by running 2 inline 255's with braided line...
