swinger 360

If on the cheap is the order of biz, got to swap meets and cruise the boards for stuff and ask for a better price. Worst that happens is they say NO.

Ideas...
TorkerII go for about $75 or so as well as Performers.
T-Q are cheap when in need of a rebuild. No different for other carbs, but T-Q's are king of cheap most of the time.
Headers could be a deal. 340 exhaust manifolds are just to much money.
Looking for MPG's. Keep the cam small. Something like a Comp 260 HI enegry cam or small extreme cam can add 10 - 20 hp alone and still get good mileage. Ask a grinders help for such a cam.
