I liked KO Swingers reply.
The biggest HFT I ran was a purple 292 in a 10-1 - 360. It was pretty good for a heavy-ish car @ nearly 3700 empty. I’ve noticed here on the board most people find a cross over point between a HFT vs a solid around the 250/255 @ 050 area. As we know, a SFT likes to make power and rpm a bit more than a HFT.
It’s combo dependent. With that said, what Hughes cams are they?
