Best 318 headers

In case you are not dead set on a 318, you could get yourself anything from a 440 to a 360 and have more power and not much money spent. My guess is that a good used engine would cost you at very most $1000.00 and then the rest is up to you.

Just another option :blob:

The 360 has been suggested to me before. I'm pretty set on keeping the car with it's original power plant, just juice it up hopefully to around 300 HP. Cam, performer intake, 600 cfm carb, the headers to connect to the existing dual exhaust, and eventually a gear upgrade. Thinking 3.55 ratio but honestly no idea what would be the best gear upgrade for the car at this point.
