will a gsr intake manifold fit a ls?

 

Nope, different bolt pattern.

 

Like he said, no, you could probably get it drilled to fit but there is no point, just go with a skunk2 or jg or something of the like

 

Actually, believe it or not we have a few ls's around here with GSR manifolds, if u got a welder around you, remove the BF valves, and the weld it back , redrill it to match ur pattern, lemme just say i've seen some ls's gain some major top end from this manifold..removing the BF is pretty much the best thing to do on the manifold like that..
