Stock Injector Sizes??

[kevinpickering]

I have a '99 Camaro SS and am switching to LS6 manifold and the guy who sold me the manifold on Ebay, gave me his fuel rail and injectors from a 2005 Cadillac CTS-V with less than 1000 miles. I'm going to use the newer fuel rail and injectors and I'm pretty sure that the injectors are bigger (which I will need, I'm doing heads and cam this winter), and the number is different on the injector. Does anybody know what the sizes are??

Your's are 26#, if you didn't know, and a CTSV is charged so they should be pretty big, but isn't it a charged V6? So you don't enough injectors?

A 400-hp supercharged V6.....i don't think so...have you heard one of those V-series on the street??? They sound amazing...I was under the impression that they had the 6.0's in them...could be wrong though...

I looked it up, this year it's not supercharged, it's an LS2, I don't know what 2005 was, but we're on the track to finding out what size the injectors are. Was 2005 the smaller supercharged engine or the LS2? Anybody?

The CTS-V is a V-8, the manifold I bought is an LS6 and came with 8 injectors.
I pulled these numbers off the injectors

Old Injectors - 12555894 (one side) / 0280155890 (other side)

New Injectors - 12561462 (one side) / 0280155931 (other side)

99-00 are 26.6#

First year CTS-V had the 400hp LS6 5.7 liter motor.

In 2005, GM made the switch to 400hp LS2 6.0 liter motor. I didn't think any CTS-V were supercharged.

Dang me and a lack of smarts, I usually get it right, mark this down cause it won't happen again
