What is the cost of the oring-spacer kit and the harness kit for those who could go either way. I know I could just call them but I figured more people would want to know.

Drag,
LS1 and LS2 fuel rail vary by mounting tabs, correct?
Besides the tabs, are the hole placements and injector mounting angles the same? Are the ID tube diameters of the rail the same too?
The reason I'm asking is that I have a set of racing rails designed for LS1 which are much more appropriately sized for big flow, which I want to use on the L76.

I'm using the L76 injectors with the Katech conversion harnesses. Comes with a plug adapter for each injector, 8 of them. VERY top notch quality. Now i just wish i could get a whole new injector harness.

ok,
I have read most of this information with anticipation; need to find out some info. I am putting an l92 in my 97 C5. I wanted to use the stock 2 line fuel rail so I had the guy building the motor put in what I thought were the l76 injectors in the stock fuel rails. He had to put about a 1/2 inch spacer under the mounts to make them work; however the connection is the same as the 97 C5 connection. From your conversation this leads me to believe the injectors are not the L76 rather some other injector. How can I tell who makes the injector? The only numbers on it are D31658A and 156. I was told they were something like 40lbs but am new to this FI stuff, had carburated cars before this. Can someone help me out? (by the way we ran the motor on a super flo dyno in this configuration and it made good hp - 569 at flywheel.)

I did a search and found nothing. I have a DBW 5.3 truck, so the L92 with the 90mm gm throttle body would be a nice upgrade. It is currently just a blower truck, but will be heads/cam/blower soon.

If I can find it I'll email you the pics of the connector to make sure they are what your're looking for. Or send me a pic of your injector end.
