Just rails, and a sensor has to b moved to front of intake. But Ill let u know how it goes. It'll b probably another month though!

 

In order to put the 60# Mototron injectors on my engine, I bought a little kit from Katech that has new O-rings, as well as longer bolts and spacers to lift the fuel rails up. The new-style injectors are shorter than the older ones. Also, my harness is different, and required a set of adapters [these are the same ones that the Cobra guys have to use when they go to bigger injectors].

So: the LS2 manifold is just a tad different, requiring an O-ring. Using LS1 rails and injectors shouldn't be different.

 

I'm trying a set of ET LS7 heads that flow in the 360's on my twin 408 set up. I'll let you know how it turns out.
