Question Differences QFT SS-780-VS and HR-780-VS
Hello

What are the differences ? Cannot be only the 100 bugs

SS-780-VS
HR-780-VS

According to the Calculator for my engine (351W 427cui, Comp Cam 300°, 6400rpm,VE 1.0) it would be the best to fit on.

But what is the difference to a Race-Carb? There the Calculator goes up to 950cfm ?? Need input

Thx
