Yeah Larry. Herb does. I've ridden in it while it did it. Quickest revving BBC I've ever seen. Sounds more like a 302 than a 468. But it plants you in the seat like a big block should.

Hi Larry,

My 468 will spin past 7k rpm with a hydraulic roller, but then I built it
with rpm in mind...

It has AFR heads (which flow very good), titanium valve spring retainers,
double valve springs, extremely lightweight Schubeck hydraulic roller
lifters (only 64 grams each), a Comp hyd roller cam - .612" & 245* dur @
.050", Jesel shaft rocker arms, shorter than stock push rods, lightweight
Scat crank (60 lbs), lightweight pistons and rods, Victor Jr intake, and
custom built headers.

I also adjust the lifters with zero preload to prevent pump up when the rpm
gets up there.  It's a little noisy but still quieter than a solid cam.

Does anyone out there get 7K rpm with a roller hyd cam?







Herb,

I have had discussions for hours about the preload on my BB. GM says 1/2 turn. I have used from 1 turn to 1/4, but never used zero. Not even Comp Cams will go there. I will try Zero for my next trip to the strip. I do realized that you have other components that aid with your performance. Especially the light rollers. Really cool! Just hope I don't blow the BB up winding it past 6K possibly to 7K. I have cast stuff, but I am willing to go for it.

Larry
