I'm pretty sure also with that swap you have to swap the heads. I'm not 100% sure but I know you have to do it on the grand prixs, just not sure on the fbody.
I looked into it a bit and remember reading that.
Correct. L67 heads != L36 heads as the injector bung is in a different spot to accommodate the position of the M90. There is the GT kit from I think ZZP that has a milled M90, but most guys just see it easier to go with a full top swap. Just can't run quite as much boost due to the higher compression.
What is cool is combining the L36 F-body intake manifold with a set of L67 heads. Two injector boss locations, perfect for a direct port nitrous system
