super six or 4 brl?

You WILL be disappointed with a 4bbl if you done do some head work(at least os valves and shave the head or deck).
Your BEST bang for you buck is 2bbl super six and 2.25 exhaust back to your free flowing muffler.
If you still have money left get a GOOD stall converter in the 24- 2800 range.
Next is head work.
