My cousin has a 67 Mustang with a 6 cyl. Now. He picked up a 289 we are gonna put in. Engine has been rebuilt, but is ALL stock. No need to go in and rip it all apart, but he wants to make a little more power out of it than stock. Basically the 'biggest' cam he can put in a stock motor and be reliable. He is 17 and only drives the car on weekends (has another car for a daily driver). He does not want a smooth idle, wants that race car idle/sound . Its a two barrel now but will be going to a 4. Gonna put on an edelbrock intake, probably something like a performer (unless you have another recommendation) and a carb. Headers of coarse. The cam has to be hydraulic, he is not mechanically inclined, so adjusting valves on a solid cam isnt gonna fly. Any other suggestions you might have carb, headers, etc), speak up! Not sure what headers work well on the 'stangs. I'm not a mustang fan (chevelle/elco guy), but I guess its good to learn Oh and its a 4 speed car. Lets hear your thoughts! Thanks.
