General LT1 question.
Are the injectors the same in all LT1's? I am swapping mine out due to the lockup problems under the higher fuel pressure associated with my nitrous. A friend of mine is running a 100 shot on his Impala SS. Should I recommend the injector swap to him too?

The Corvette injectors were the same from 1989 through 1996 - they're a Multec ball-valve injector. I don't know if LT1 F-bodies and Impalas used the same injector.
1985-1986 cars used Bosch injectors. 1987 cars and most of 1988 used Lucas injectors. Late '88 cars through 1996 used Multec. In 1997, GM went back to Bosch.

Re: General LT1 question. (Lord Odin)
I would benefit due to my higher pressure with the nitrous use. The stock injectors are prone to lock up under the higher pressure. Thus, causing lots of damage!! Here's 95BLKVette's oil pan after a mis-hap. I want to avoid this!

If you can find a copy of the March 2003 "Corvette Fever", it is an issue dedicated to fuel injection issues, including basic sizing calculations, duty cycle recommendations, etc.
