Think about it like this... an engine is really just a big air pump. The more air you move through it, the more power you make.
The first thing most people do to improve performance is to put on a better (higher flowing) air filter and a better (higher flowing) exhaust.
Your 307 probably has a 2 bbl (barrel) carb on it. You could try and put a 4 bbl on it, (but you need a 4 bbl intake) it would be a start.
You can actually call Summit Racing, and talk to a tech for a carb application for your engine. The basic specs are 2 or 4 bbl, and how much cfm (how big, how much air they move)
Installation is basically four bolts and a gas hose and some linkage.
Hope this helps.
Exactly!
The folks at Summit are pretty good. If you tell them what engine it is, they should be able to hook you up with an intake manifold, carb, and some advice regarding jetting and metering tubes.
Edlebrock carbs are pretty good for the price point. Holley, Demon, etc are good carbs but pretty expensive (especially if you're just trying something out). I just sold a cast iron 4 bbl intake for a small block Chevy...probably would have fit your car! You can probably find an intake manifold and carb used for a few hundred bucks. You'll need to buy a new intake gasket though.
