I have a Gen IV intake manifold that looks similar to a TBSS manifold, but with rectanglular ports not cathedral. I am trying to find out if the injector spacing is the same as a car manifold. I think the manifold is supposed to be '09 or '10, but I don't recall. Will any set of Gen IV rails bolt right up?

The spacing would have to be the same. The ports on the intake side of the head doesn't move between a car and a truck does it? The injector is aimed at the backside of the intake valve on both the cars and the trucks.

That's what I was thinking too, I just wasn't sure if for some reason they might be offset differently to accomodate something that was different on one than the other. I just wanted to make sure before I went out and threw down money on something that might not fit.

Here are pics of a L92 carbed intake from GM that I did a few years ago. The injector bungs were not drilled. I ordered a set of LS1 aftermarket fuel rails to use, measured off them, then set it up on the mill. I indicated the first bung in, by the time I got to the last one, it was clearly off. It functioned fine, but all the injectors weren't centered in the port.

I doubt the error was on your part, you should see how bad the quality control is on a lot of the newer edelbrock products. Woudln't surprise me if there was some core shift going on there.
