Send it to Andrews, they could tell you all about it.

I would forward the guess the lift stands for 512
Not worth screwing with.
Get a better cam.

Could be a killer cam, but w/o dedicated specs, who knows?

You could measure the lift EZ enough.

W/o the opening closing, duration, etc, purely pissing in the wind.

Lift is only one single aspect of a cams profile, and not necessarily the most important value. How can you state that it's not worth screwing with when you don't now what the motor is, stock, modified, or how the bike will be used?

You here for an argument?
I just 20 dollars a minute.
How can you say it is a great cam?
I will bet it is trash.
I googled.
Looked in the pile of crap I have.
Dreamed about it, and have concluded- it has not become famous for obvious reasons.

No, I just asked you a simple question, and I stated nothing about the cam being a good or bad cam, as I know nothing about it or it's intended use.

If one was truly curious, they could install it with the degree wheel and all and see what it says.

Measure the open close events.
Lift.
I have a feeling it is not a classic or there would be a lot of them somewhere.
or send it off to Webb Cam.
For two hundred bucks they will write it up.

   If I had to make a SWAG, I'd say its an S&S, later called a #514, but its a shovel cam. They used a # system based on lift, but as a Shovel cam it was the same as a #3, both made by Andrews. It was a good Shovel cam for small strokers, and someone could've thrown it in an Evo without any major trouble. The specs on it were 29/49 inverted for both lobes, with 512 lift, 246 dur., and .125" center tdc lift. It could actually be a decent cam in a stock evo, but as I'm saying just a guess for now. If you have a lathe & dial indicator, you could confirm the specs with a little ingenuity.

Comp Cams will plot/reverse engineer.
I looked up some old Three Suns info......nothing close.

There's nothing in the master cam sheet that uses AQC. 

It could be something that was made by one of the off market suppliers for a box seller, like Carl's. 

You can measure the lift with just your caliper and a little math.  Duration requires a set of v-blocks, a dial indicator, degree wheel and a good guess as to where to measure from.  Timing is even harder.  Prolly a case to mount it in would be the easiest all around.

I believe that cam is from American Quantum Cycles. They were building custom bikes with their four valve heads for a while back in the everyone is a custom motorcycle company days.

You may want to have it traced and sell the numbers to the M-8 guys.  :wink:

That’s interesting. I had to look them up. A “patented” 4 Valve head.

The Rivera, Quantum, and RPMHemi 4 valve heads were all under Jim Fueling's design and patent. With a little work they could make good power but there were other areas that needed some work.

A little off topic but what ever happened to the poster 'gcc motors" that started a thread on some newly developed 4 valve heads he / they were working on for twin cams?

I remember the thread well and also wondered where he went.

Hmmmm .... maybe a PM to him will wake the thread up (or a new one). With all of the R&D that'll be happening around the M8 the heads he was talking about may be an interesting way to get the twin cam on a new level. 

added later

PM sent to gcc motors  :wink:
