Hey, I'd like to here from others that are running TBI on their engines whether its run by MS or GM ECM. I'm about to take the plunge and build up my 250 with the Offy intake and GM ECM. I think it will run very well since 4.3L and 4.1L are very close in C.I.D. Please chine in and give your input.

Thanks in advance.
