This is the GM (Chevrolet) Performance Pontiac RAIV camshaft #12364044. Last time i checked it was the Crane "blueprint" series camshaft stamped "968".

This is the first I’ve heard of this version, wonder if it’s still the same core & lobes as the “blueprint” version?

Here is the Summit RAIV camshaft:

Crane supplied the "GM Performance" camshafts. One popped up here recently in the classifieds section

It's been a while since I bought a RAIV but I went through
Auto Zone and then it was only around $125.00. Don't remember
how long it's been though. Try them and see. It was a melling cam.

Just checked at AutoZone. SPC-8 is $295. Ouch.

Anyone ever run the Edelbrock 7157 041 cam? I was pleasantly surprised to find one of these with some parts that I bought a few years ago.

That cam was in my engine when i got the car over 10 years ago. It vent flat abot 2 years ago, and i pulled the engine an added a topend kit and converted to rollerc am with same specs. I have no other flat tappet to compare it against, but for me it ran ok, and hard a bit of a lope to it, ok vakuum.

That used to be the cam supplied in their RPM "top end" kit when you bought the whole package (cylinder heads, intake, camshaft) and they would advertise something like 450hp and 500 ft lbs. on a 455 combo.

I remember people in the late 90's buying that package and using it with decent running cars for the time. Not even sure Edelbrock still sells that as a package deal or not.

I have the info on the Compcams RA4 cam that went flat during the break in. The flat lobes are right below the caliper in the photo.

The width of the base circle was the narrowest I have ever heard of .506”.

The cam is about 3 years old. What is most suspicious is where CWC is cast into it. The lettering does not look like an old molding that has been used thousands of times that you can barely read. It looks clear, like it is new. It looks very suspicious to me, like something you might see from off shore stuff, at very least that is from a new mold. I’ll let you be the judge though, here are the photos of it.

A cheap copy perhaps? I wouldn't be surprised.
