hey the 4ac is not gay it happens to be the same motor i have been driving for about 5 years so play fair your 4ac is gay maybe but not mine i have a 4ac with port and pollish, 3 angle valve job, shaved 30 thousanths, weber outlaw top draft carb., and a 2" inch manifold back exhaust w/ no cat. and a Pilot flow threw muffler. it has balls like a beat up 4age that hasn't had a oil change in 18 months but it does what i need..........
