Highest flowing sbm heads?

Impressive ET’s it laid down


There was some left in it. I didn’t have much adjustment on the clutch and I didn’t even have single adjustable shocks on it. I had 3 ways on both ends. And they sucked.

If I had some decent double adjustable shocks and a clutch I could easily adjust base pressure and play with counterweights I would have got some ET down a bit.
