Hey guys, what is a reasonable power limit for 42 lb injectors?

Thinking about putting a 600 fwhp sc 351 together. EA 3.0 says that I will need 50's +, but I dont know how accurate that calculation is in EA. I've heard 550-575 rwhp, and that is pretty close to 600 fw. Any advise?

if your aiming for 600 Flywheel HP, the 42 lb injectors should be fine...what does the rest of your fuel system consist of?

Just be realistic with yourself, is that all you'll ever want? Or will you want 700? 800? Buy them once and buy them large enough for your future "urges".

Heh. Honestly, I scored a S-trim cheap. The 351 as it is right now is quite a handful. With the boost, I think I'll be fine for another year or two. That 600 fwhp figure is assuming 9 psi boost. The head unit is capable of 14 or so, meaning I have room to grow. Also, I really don't want to get into high impedence injectors. Getting the driver for them is more $$$ on top of the big squirters.

Fuel system is still being planned. This is a 68 mustang, and I was thinking 255lph inline and a T-Rex pump further up stream. I dont know about the self priming capabilities of the 255, so I need to do some more research. I might just have to spring for an Areomotive 1000 or so. At least 3/8" pressure and return lines. You guys have any suggestions?

Go with the Aeromotive pump and forget the 255 and the noisy T-Rex.
