SBC Cam Identification Please Help

I am installing a cam into a Goodwrench 350 engine & I don't know any of the specs on it.

On the rear of the cam it has the #968910
Here are some of the other #'s on it...

3R
1579
26 (red paint mark)

One of the cam lobes measures approx .456 lift with a 1.5" rocker

I installed it advanced 4deg. as it's being combined with a torker 2 manifold in a street driven s10

Any help any of you have would be very much appreciated! Thank you.

I have the (un) obvious question. Why would any one install a cam in a motor (any motor) without knowing the cam specs? Isn't about the same as taking a blood transfusion before knowing the blood type? Just my 2 cents.

You're reading my mind.

I bought a built 305 for $85 & turned around & sold it for $165 without the cam, lifters, timing set, chrome timing cover.
Kind of hard to throw away a cam & lifter set that I removed properly & in order. The lifters are still convex & the hardened surface on the cam is fully in tact.
I'll be evaluating how the engine runs well before it goes into any chassis.
It'd be nice to know what duration, overlap, & LCA it has so I can be a better judge if higher compression is in order.

Keeping the lifters in order works if you're puttin' them back in the same block, but once you change blocks, all bets are off. The blocks are machined on a large volume production line and there are no two that are machined exactly the same, so lifter bores and cam bores can be very different one block to another even in the same block series.

I knew that.

Core shift is obvious.

Then why are you going to risk wiping a lobe and creating more work and expense for yourself?
