View Full Version : Will the stock fuel system be ok?

01-03-2008, 02:43 PM
Just curious to see if the stock pump and injectors will be ok for my application. I'll be swapping in a set of Patriot LS6 style heads w/ 64cc chambers, 2.02/1.57 valves and I'll be using the early graphite gaskets to bump the compression a little (10.7:1 as opposed to 10.5:1). I'll also be swapping Patriots .580/.590 225/229 114 cam. Do you all think the factory injectors and pump will be ok? If it matters at all, I do have the Racetronix hotwire kit on the pump and the pump is brand new. Thanks in advance!

I would get a set of Ford motorsports 30lbers at least and install the pump!:D

Stock pump will be OK for now but you have to have new injectors. SVO 30lb will be OK if no further mods are planned, 36lb will give you some breathing room.

You'll run out of injectors before you run out of pump. If you are going to upgrade injectors, go bigger than you plan. I went with 36# and @ 470 RWHP they are at 73% duty cycle. If I had to do it all over again, I'd go with 42#ers.

30#ers, that's what I thought. I just so happen to have some brand new Accel 30# injectors waiting to go on my '71 Camaro project that's going to need bigger injectors anyway. I might as well use them. Thanks guys!

Ok, I have some 30#ers, which'll be ok for my application. Say I wanted to move up to 36, 39, or 42#ers, will a brand new stock pump with the hotwire kit still be able to feed them? I'm thinking not, but I'd like to hear your opinions.
