Well, you're just a genius, aren't you. I read the thread. I have a good block and have about 30 years of airframe and powerplant experience which I think gives me the ability to put some goddamn cams in a car. I'm not backpedalling and I'm not questioning the product.

You posted at one point - and you seemed upset - that only your friends bought your cam sets.

That's about all you'll get with the methodology you employed. I'm sorry I feel that way with the information at hand. I don't know you, and I don't really want to now.

Too busy for flame wars with old guys on the interwebs. I'll let myself out.

I see both sides for this. I understand your frustration, Stimpy, but you are being a tiny dick about it. Where else can you find a set of performance cams for $450??

If you're genuinely interested why not say to Mike: "Hey, I'll buy your cams for full-price, I'll install them, and I'll post before and after dyno runs; and if I do all that how about kicking me back $225?" That may have worked better.

Taking the elementary school approach was a bad idea.

I will repeat what I asked the new guy, what are your engine re-build plans? because you cannot just pop these cams in, you need to do your heads. You do understand why, right?
Yes I do understand that when the base is cut the valve stem will have to be longer or shimmed to take up clearence. I also understand that this will also change the angle of the rocker arm and push the valve sideways more than it already does. If base is cut the best way to keep geometry correct would be to raise the lifter the same as valve stem gets raised. I also understand that cutting valve seats will lower comp and that valve timing can still fill the cylinder. I have been building racing motors for harleys since the 90's. I change my own guides and grind my own seats. I assemble everything after I get it back from machine shop myself. I understand the trouble you went through to get these and love that you are willing to pass on your good fortune. please pm me if you will give up the info thanks for your time.

Well, I don't understand... is this because the cams are reground and their diameter is smaller?

Yes smaller diameter means cam is farther away from rocker arm. clearance needs to be taken up somehow. Either taller rocker arm, longer valve stem or taller lifter.

Yes Luke, I explained that to you. They are "Short" by 30 thousandths and that's why you have to do the heads and a valve job, to compensate for that.

Well I can see that you clearly understand, not like that other clown who was just fishing for free stuff.

Since these are nearly direct, perfect copies of stock 822 cams with only a "Slight" modification to get around copyrights, There are no surprises with my "Design" since it's MB's design.

I will give you a Cam Card with your purchase of a set, but I will not just give out the specs to everyone for free.

Thanks Mike. That conversation was many months ago and information leaves my short-term storage quickly.
