then you can use various different TBI's.. you are going to need to install quite a few sensors and such to make TBI work correctly.. but most likely you are well aware of the stuff you need.. I used a 4 BBL to TBI plate on a 454 years ago and it seemed OK.. though I always felt like TBI didnt flow well enough for my application.. the 366 has many similarities to the 454 but also many differences.. some of the TBI's fit right into 2 barrel carb spots.. perhaps a 454 TBI throttle body would fit in the 366?
for the ECM theres many choices from OEM with chips all the way up to Holley made (and priced) products..
I used holley pro-jection years ago.. i also did a project with megasquirtm the learning curve to get up to speed was steep but it did work very well..

Thanks for your reply Chris.
As far as I understand using the TBI from another Big Block like a 427 or a 454 is not a
problem, so long as you flash the controller chip with the right file, you're good to go.
My only problem with that is finding a Big Block to salvage the TBI and other required
parts from ( the search is on going ). Another possibility might be to use the TBI
system from a Small Block Chevy, but I not sure if it can be done and nobody else
seems to know if it's doable either. Finding a salvageable Big Block might be hard, but
finding a donor Small Block would be much easier.
The FiTech TBI system looks to be a reasonable alternative since GM decided to stop
producing the Rochester TBI.
