With our weird camshafts that would be a challenge.
Bill did try fuel injection quite some time ago. Thinking mid to late 90’s. It was very consistent, he won a super Chevy show race at Portland with it but was not able to run the index. Dual quads were faster by a bit and carried less horse power. To be fair they were on a tunnel ram with porting and the fuel injection was an untouched original manifold. He might have used the later 327 injectors, memory fails here. Maybe a sheet metal manifold would help? Specific questions might jar the memory so ask if you have any!
