LT1 Injectors work on TPI?

I have a chance to buy 8 24# injectors from a LT1, will these work on my '91 TPI? The OEMpart # is 17121068. Thanks.

Injectors are basically injectors with the exception of low impedance ones. Usually though they are high flow. Some of the LT1 injectors are 22 lbs and some are 24's. If you wind up getting 24's you will have to recalibrate the prom to compensate for the higher flow. But to summarize yes they will work.

Yep, I used some 24# LT1 injectors on my L98.

Not that anyone would want to try this(wouldnt make much sense flow wise), but you cannot use the L98 injectors on an LT1 though due to their impedance.
