Cams

Has anyone ever heard of a cam with 0.465 lift. That is the best guess I can get out of the cams I removed from the mystery engine. Roy

Bump. :laugh:

remove a zero---.465 inches is a plausible lift measurement for a set of very wild KZ1000 cams.

Thanks, I just never seen the lift advertised. Roy

A couple cam makers list that lift...

Megacycle lists 2 versions.....470-85 and 470-x15

470-85 .465 lift 270* dur. 108* l/c
470-x15 .465 lift 264* dur. 108*/110* l/c

Cam Motion......Z9 .465 lift 274* dur. at .050 lobe center 110*

Hey Roy, don't forget that the base circle on stock cams is about.962".
So when you just roll the mic or calipers over the lobe to get the highest measurement
does not mean the gross lift. You have to subtract something?
Let the Machine shop Head guys tell you.
Do you have a set of stock cams layin around to compare?
I looked at some stock used cams. there total measurements were about 1.418" -1.420"
across the lobes.
Did the head holding them cams have machined relief clearence spots on top by the lifter buckets?
Was it using shim under buckets?

Cans of that lift usually have a 1.00" base circle. Stock is 1.110"

I measured the lobes and subtracted the base circle. And yes the head was clearanced.

Thanks racer, I am just trying to nail down who made these cams.

Thanks Jay, I guess I could put all these parts in the lay down frame I have and just look at it and make noise at meets !

It was suppose to be Mike Brusso's bike!

Converted from shim-over-bucket to shim-under-bucket.

Good Fortune!

I will have the head apart this morning. I don't think it has stock springs in it. :S

I am going to sell the whole package together. Roy

Here is the valve keepers and buckets. Are these stock 650 parts?

I'd have to have get mine in front of me, but it looks like the 650/750 parts at a glance...
