Opinion: Small motors more or less consistent than big motors?

Well, by choice I'm not very conversant with GM stuff. But, I do happen to know for sure that early 90s (at the very least 91 and 92) Camaros/vettes were Speed Density and had no MAF sensor. If you disconnected the MAP sensor on one of these it was basically a vacuum leak, so I could see how that would be faster if the factory mix was rich, as it usually was back then.

I helped a couple of friends that had those cars back in the day. They were constantly getting their lunch eaten by 5.0 Mustangs and turbo buicks.

I don't know about previous to that (thank god). However, it would be just like the General to go to MAF, back to speed density and back to MAF again.
