Has any one on here used knowltons thunder heads for heads and or a complete set up ? Do they do their own lower end stuff or just ship it out and
put their ported heads on ?? Thanks

I'm not going to be much help but, Glen and Travis are very well known around the Twin Cities area. Know alot of Olds guys up there have had them port their stuff. It's been a few years since I have been up there,but I do remember some machines to do the lower stuff. So it isn't farmed out. I know of at lrast one Olds vendor that has them CNC port the Edelbrocks he sells.
He also had a set of wierd looking heads that looked like olds but strange internals. They were involved with Randy Mans (Division 5 Olds Super Stock king) and his head developement. Anyway the Knowltons are well known and respected.

I have their stock-valve CNC-ported Edelbrocks on my 468.
It made 570 hp on the dyno, but it's not back in the car yet.
Travis was great to work with.
