Highest flowing sbm heads?

be curious to see those moved center heads actually go down a track and see a time slip.
up until now they have been notorious under performers

My mistake I forgot to mention the moved centerline.

I know a set of heads done out there that made 800 on the dyno, and ran 9.80’s(133 or so) in a scienced out super stocker, that weighed 3200 ish
Long way from 800. ET slip will tell the tale

I agree 100%. I cant reveal what Brians customer runs but it is would shock you at how fast it is at 3100 pounds. Even in nitrous trim. And I highly doubt Bretts numbers are inflated. There is a guy here on the west coast deep in the 7’s with a Miller motor. They claim it makes 1050hp and the mph totally supports it.
