I have a friend that has a throttle body injection on a 1950 Buick straight eight that works well. The Buick head is the same design as the six cylinder Chevy---lousy manifold design, crappy head design, and siamesed ports with the main difference being it has two more cylinders. I built him a computer controlled HEI distributor which ties into the injector controller and it worked much better than the separate systems. A PM will get you his name and phone number.
