im wanting to put a set of lt1 injectors in my 89 350tpi iroc ( have currenlty 5 bad injectors). Think the irocs injectors suppose to be 16 ohms of resistance when good, and the lt1 injectors have 12 ohms of resistance when good, will this be a problem. read some on here using lt1's on stock cars just wantin lil more info. any runnin issues? does car run better or little rich? anything?


had these on a 91z with 383 tpi but never ran right anyway so i swapped to carb on that car.

 

If they are from a 1992-1993 LT1, they are the same as the 350tpi uses. 94-97 LT1s used 24lbs. You'll run a bit rich, but should be fine. I have 93 LT1 injectors in my car and its fine.
