I have an 87 with a 305. It currently has a Edelbrock intake and Holley TBI. It once ran strong, but we can't figure out what's going with it.. it dies when hit the gas. It's now stumped two mechanics.
Don't give up on the TBI yet. You need to data log the engine while it is running and see what is going on. Without that info any mechanic is just guessing at what is wrong.

All you need is a data cable, a laptop and a piece of free software to read the data with like TunerPro RT.

The guys at thirdgen.org have a bunch of great info on DIY PROM tuning and data logging is part of it.
