I am doing an engine conversion and have a 2000 LS1. I thought the injectors are 26lbers so I obtained a free set of injectors off of a sub 1k mile 2001 Corvette LS1 thinking they were 28lbers.

They look almost identical, even the part number on the side is the same.

Maybe I'm confused, but just didn't seem right. Anyone know the part numbers or another way to determine?

TIA

Heres a bump to ya as i'm interested in how to tell the difference also.

Thanks. GM does in fact have different part numbers. But, after talking to a few Parts/Service ppl, I think the numbers on the injectors are nothing more than a mold number or something. Although different part numbers, they have the same form factor. None of them were able to look at the injectors and determine which part number they were.

I do beleave the numbers are the same on one side as a 26lb but the other side should be diff--i want to say either the first 3 didgits or the last 3 i think 26s 28s are a dark grey almost black here is the number 12561462 for a 28

Interesting. Mine are not as dark as the ones on ebay. In fact, they are identical in color as the 2000 ones I pulled out.

A base LS1 01 C5 had 26 lb injectors.
Only the Z06s and 98s had 28 lbs.
