Guess it also depends on other mods you have. Way back when, I was told 42 lb/hr injectors were fine for I/H/E H/C and a 100 shot. And that's what I used... for a few weeks. I now have Siemens 60 lb/hr injectors and plan to go up to a 62 jet (150ish) dry. Probably way over kill though.

So, you'll be looking around 450-500hp on the juice?

I think you'll be stretching the 39# injectors a little bit. I'd suggest a 42# or 50# injector.

Welp, the only way to be certain is buy them and gradually increase the shot while continuously monitoring/logging your injector duty cycle and checking spark plugs. If you stay under 80% with the 200 shot, you're fine. That's what I had to do. If the Ford 39s are too small, just sell them and buy bigger ones.

We've priced our injector sets competitively with others in the market.

The LS1/LS6, LS2, and LS3/LS7/L99 engines all use different injector designs. Just because the LS1/LS6 is an older engine, doesn't mean we are using an older injector design.
