If you use a ford CFI out of a '84 ish 302 they are 1/2 carb 1/2 TBI that use normal bosch injectors - easy to find the right size injectors. By using a boost referenced fuel reg. you can get as much boost as you want to run without hitting the injector pressure limit with the GM TBI units. Install 3 of them to get enough airflow as they are quite small. Blow thru should work ok.

Cougars are a good place to look.
