Blue Racers are made by Crane not Comp.

Blue Racer division is closing up as Crane reorganizes their brand name(s). It is being partially replaced by the "Blazer" name in their line up.

I doubt the fact that it is a regrind was the deciding factor in the lift. Cam manufacturers, lead by Comp Cams (if you were following above), has promoted the growth of higher and higher lift as the answer to everything. It helps make power if everything else is right, but duration and lobe separation are so often wrong for the application that shopping by lift isn't always the answer. Some of the more helpful cam co's give lift at .200, which is more essential to how the cam will flow that peak lift. Usually duration at .200 is between 110 and 170 deg.

This comment is not directed at your instance- I have no idea of the details of your build up- more just a general observation.

the lobes that paeco use to grind their cams are not the latest fast opening, high lift profiles. You may lose a couple horses for that reason alone. Also their lobe separation on the B18/B20 OHV engines is 110- too wide for optimum power.

Also many parts in the catalog are no longer available. They listed weind air cleaners for several years after weind stopped making them. I very much doubt that they had that much stock. I seems like they wanted to bulk-up their catalog.
