318 head porting for the average joe

It runs good but it's just a dog. Starts easy, even though it still has its lean burn it had since new. THAT WILL be going away.
It loves cruising 70 down the highway, it just don't have any balls, can't hardly pass anyone if I need to. I rarely try to get it to much over 70, (it definitely will) but I am in town at lesser speed just as much as on the highway, and it needs help getting out of it's own way.
In addition to waking up the engine I'd like to swap to something around 3.08 gears.

If you want more, the factory performance gear was 3.23's. Assuming you have an 8 1/4 rear that would be 3.21's. I can't remember what is in between. A Sure Grip would be nice. Next would be to swap a performance electronic distributor setup similar to a 73 340 so you could set and vary your timing. See Hailifaxhops. You could also swap to a 73-75 Carter 318 2 barrel carb and ditch the lean burn stuff. Sounds like a real nice highway car. Next would be a cam and double roller ting set. and a 360 intake and TQ. See, it gets crazy fast... Good Luck.
