85lb injectors on stock pump ?
85lb injectors on stock pump ? Will idle and part throttle driveability be ok with 85lb injectors on a otherwise stock fuel system?
This will be on a stroker motor running 93 oct

WARNING!!!! lol i had 78# injectors that scaled to 90ish pounds that ran terrible at idle, cruising and part throttle, of course that is on my stock cube ls1. hope you mean stroker and not stocker motor then you may be safe. my car is h/c/i and the idle was bad and cruising was good, except when i would be off throttle it would go rich like 12-13 afr. idk if added stroke will help but for my tuner the car was a headache to work with. Plus for my car the injectors were only at 35-40% duty at WOT. Tuning the pulse width to 1ms couldn't even fix the issue.
Yes I mean stroker not stocker lol - stupid spell check.
Motor is a 416, will get FI in the future. I plan on just doing a upgraded aero 340 pump.
Id rather not go return .
Is it possible or will it be a nightmare to get it to idle and run right with the 85s ?

My 5.3 idles fine with 80 lb dekas. Your 416 should idle better.
You're going to need more than a 340 pump once you want to go forced induction, and you're going to have to go return as well (even if dead-head).

Ya it will be forced induction but mild, shooting for mid 550 wheel on a awd Tbss
I was under the impression the stock hat and regulator could handle a aeromotive 340 pump. I see a lot of people just drop the pump in ?

Ya 4l80e and awd robs a ton of power.
I would prefer less cube but it's what it is so I'm going to work with it.
My goal is to try to keep it a street truck, a lot of the boosted Tbss guys have cooling issues.
