What's up Johnny?
Yeah I hear Ya......With my backyard mechanic skills I'm a little confused also about portong with motor in and porting with motor out...
From what I inderstand is to port the more " important " part of the head, the motor has to come out....With that I say, with the motor in and doing whatever porting you can, how much horsepower and breathability will I pick up? 20-25 RWHP?
Hey, maybe that's good enough without having to pull the motor, am I right?
I think I see Evolutions point about pulling the motor because you have access to the cams at that point.......
End result is- how much are you willing to spend to get more useable power? That's the question....
Or, you can just pick up a C5 Z06 with a head and cam package, and if your lucky enough a supercharger and be done with it...Lol..
Peace ...
