Alright, this is new territory for me. I have no clue about domestics. My friend has a 1995 C/K1500 pickup (extended cab, long bed). I made the mistake of showing him the little trick where you flip the air filter cover and he loved the power, and especially the sound. He's got headers on the way and is planning true-duals with flowmaster 40 series mufflers. What else could give him a bump in power without breaking the bank? I was suggesting a cam, but I've never put one in a pushrod motor while the engine was still in the vehicle before. Also, we're not sure if his motor is the 305 or 350. We know it doesnt have the vortec heads if thats any clue to anything. Thanks for any help
