Are you serious? Lol. 60's were what I was told to get. Am I just taking bad advice everywhere? Haha

Out of curiosity, what 80 pound injectors would I get? The 60s I have require pigtails. If there are 80s that are the correct height and plug right in, I might buy those and sell my 60s.

FWIW, my truck is heavier, runs 11.6's in 4x4(front diff still alive), cuts 1.59 60 foots, and all on 42# injectors.

Run the 60's until your datalog shows that they aren't cutting it anymore.

Did I miss what displacement the engine is? I ran 20psi on my 4.8 with 50% E85 with 60lb injectors shifting at 6400 and I think it was like low 90s duty cycle. The 60s can flow some fuel...

It's a LM7 if I'm not mistaken.

5.3L. I think if I blow it up I'll swap a 4.8 in.

If your reasonable with the tune, run good fuel with good fuel pump you could touch 10s if you wanted to.
Id do head studs and head gaskets to be safe.
Everything else looks good..


Show the ole jeep guy Atomic's truck and stock48's truck.. and then see what he says.

I just ordered my areomotive 340 and submersible fuel line. I'm going to wait until it shows up before I order the wiring kit. I want to make sure I order the correct one.
