1994 m6. with the mods below and a port and polish job matching gaskets both on heads and intake manifold, milled just a lil, cc306 cam with 1.6 rockers. and a tune.

 

it all depends on the port job, You will need COMP R lifters and probibly different pushrods if you mill your heads, and a computer tune to get the most out of that cam. You will have to really rev that thing to use all of the powerband on that cam, i hope your bottom end can take it.
