Andyhall, confused yet. Deve, you look forward to what happening, EFI on stovebolt or what everyone is talking about, sequential, multi port blah blah blah. There's a couple as stated that are running very well on TBI. Your distributor conversion is a good option for getting HEI and spark timing control with the GM TBI computer. It's a relatively easy and inexpensive conversion compared to the others mentioned. And as the saying goes, if a knuckle head like me can do it, anyone can. As a side BillS' TBI tune was pretty much spot on as found with real world driving and monitoring via laptop.Good luck however you go Andyhall.
