FBO plate over advancing

I haven't driven an old car with an efi system installed. But I'm not interested either. The engine is the same regardless of carb or efi bolted in place. So any gain in performance or response with efi would have to be minimal.
I agree. .....and I'm no expert on the differences, BUT, everything I've read and heard people say who KNOW the differences say that carburetors make more peak power every time. .......and the EFI crowd always blows up. lol
