Aight, here's what I've got. A crate TBI 350 for my 87 K5. I want to do some performance work to it before I put it back in the truck. Here's what I was thinking: Balanced RV cam (something fairly bumpy) roller rockers maybe port and polish job headers I want to get the maximum MPG out of this motor. I'll be running a 465/205 in it with 3.73's and 33's. Does that sound like a winning combo?
