Default Injector ?

I have a LQ4 to go into an 87 Olds 442. I have had the heads milled .025--a Comp 224-232 with .570 lift cam. I recently purchased a LS6 intake with injectors. From what I can gather the LQ4 injectors are 24.7 and the LS6 injectors are 28.8. Are the LS6 injectors enough? I hope so. I don't know what HP the LS6 injectors supports. I welcome any and all replies. Thanks--Lee

If you find that you are running out of injector with either the truck or the car injectors, you might want to look into "decapping" them. I and multiple other people have done this with good success. The best part is it's a lot cheaper than buying high dollar aftermarket injectors. You will need a way to flow test them and also a way to adjust the IFR injector flow rate though....

You are going to be at the upper limit of the stockers. They will do ok for now but plan on upgrading later if you plan on turning some rpm, say 6k plus.

Default Dust Caps = Flow ?

Hi Lee, I ask about the dust cap, what is stated here is that the DUST CAP is a flow orifice ?
Would that case be to JUST FIT a LARGER set of dust caps ?

I would fit our 45 .lbs Denso "long" injector with better Idle Quality than OEM 28's.
