Check out your engine core very well before paying a bunch for a new fuel system. A lot gets blamed on the TBI with its associated wiring issues. That's the reason my TBI engine got pulled. I suspect now, that a lot of the problems with run-ability and power were because of wiped cam lobes. I'm told it's a common problem with those flat-tappet engines.

Check compression, do a leak-down test, pull the valve covers and confirm that the valves are all opening adequately. If all that checks out, then consider spending money on the fuel system.

Keep in mind that any system you go with; carb, TBI, aftermarket injection, or LS swap, you'll need to learn it thoroughly and plan on doing all repairs yourself. No mechanics remember how to diagnose and fix the old TBI stuff, based on my experience. Likewise, you can't assume they will be willing to work on anything aftermarket. If you're going to the bother of learning a system, it might as well be a LS.
