Difference between solid roller and flat tappet

Considering your bracket racing, I’d stick with a SFT & seek an aggressive fat lobe cam. I see Solid Roller Cams as ether for a good solid street cam or a balls to the wall race cam, which of course are two way different lobes... I know....

The limiting factor for there use is really there cost, for the street, it’s a pricey endeavor that you have to be OK with there cost. At the track, it would be a heads up class I’d make there use in. And if it is a heads up class, your spending big money.
