Default LS1 and LQ4 injectors the same?

Are LS1 car and LQ4 truck injectors the same? Do they have the same plugs? How about the flow rates?

No, the truck injectors are shorter and have a diff. plug. Don't know what combo you have but most people use the 8.1L truck (30lbs) or the 8.1 marine (42lbs I think they are). You can use the car injectors but you'll have to space the rail up and change all the plugs, really not worth the trouble.

Thanks for the input... I'm thinking more along the lines of using a truck harness on my project, and was wondering if I would have any problems around using bigger injectors (48lb to 60lb)... probably should have mentioned all that in the original post.
