What is so baffling?Why people still use carbureters baffles me.
There are guys who have been building race cars a certain way for their entire lives and are now 70 years old and have never used a computer for anything. (Yes, 95wagon, there are also guys who this does not apply to).
If you are an expert at one thing and a noob at another, it's understandable that some would prefer to stick with what they are good at. My good friend is still running a carb'd SBC in his Caprice, and the car sure as hell doesn't need to be any faster. He has no reason to learn how to tune. "Efficiency"? That's cute.
I can't tell if you are being completely serious here, but the head flow numbers are just the beginning.Why does everyone swap LS motors? The intake port.
