15a 21a 13G?

I just pulled the 13B from the REPU yesterday for some work and noticed how far forward the motor mounts are. Yep, looks like a 15A could nay should have gone in. It's a truck with a rotary! A 15A would have made a lot of sense back then before the age of EFI and turbos. 135 bhp at 5750 rpm and 196nm (145 lb-ft) at 3500 rpm for the 15A compared to the 74 13B's measly 110 hp at 6000rpm and 117 lb-ft at 3500 rpm. Which would you prefer if given the choice?
