Say 22 to 24,you are OK. 22 to 30,no. If you have multecs, replace. If you don't and the rail is off or almost off, getting a reman set will be cleaned unlike using snake oil

BTW, your injectors will probably have built up residue in them. That affects spray patterns and volume. Unfortunately it cost as much to clean them as to get a reman set so might as well unless you need it original. Check out if you have multec or not. IDK with your year.

I believe the stock rate for LT1 is ...disregard. I posted misinformation.

My '92 LT1 is rated at 22 pph for the injectors. This is what I replaced my Multecs with.

I just ordered this set of injectors: https://fuelinjectorconnection.com/c...roducts/92-lt1

Hopefully once they are in it will fire right up!

I just hooked up a noid light and it blinked nicely, so it looks like the new injectors should do the trick!

I got the injectors in yesterday and it fired right up! Everything seems to be working nicely and it runs great. There is a bit of shaking at about 50 miles an hour, I think that is because the tires have flat spots from sitting so long.

Engine shake or chassis? Old motor mount?

I am pretty sure it is not from the motor or drive-train, the motor seems to run very smooth at all RPMs. I had a similar experience with a Mercedes that had sat for a few years, it shook at certain speeds down the road, it got a bit better over time but only went away once I put on new tires that did not have 'flat spots' from sitting.
