81 Camaro Z28 Engine Swapped to Chevy 454 Engine.

It appears to me that this will put the car into CP?

Naturally aspirated cars using US-market 6-cyl and 8-cyl engines manufactured
by a particular corporation may use any naturally aspirated 6-cyl or
8-cyl engine offered in a US-market vehicle by that corporation’s brands as
listed below:
General Motors: Chevrolet, Pontiac, Oldsmobile, GMC, and Buick

Engine displacement changes are allowed.

I don't see anything in CP about it having the engine restricted to the same car family, just the manufacturer family.

Does anyone see this differently?

Thanks!

A BBC Z28 meeting the rest of the ruleset would go in CP, yes. While that would make for a very cool car, you might find it's not the quickest way around most autocross courses. You're not allowed any engine setback and a big block would put a lot of weight over your front tires. Also, CP has a big weight penalty for going over 5.1 liters displacement. Would CAM be a good class for it?

CAM requires valid tag/registration and insurance, I believe... which I don't think is in the plan for the Z28.

The registration thing makes sense wrt CAM classing. The national trophy winner and national champ CP cars I've competed against are generally very light and purpose built. They also tend to have 5 liter engines for the weight break. For instance, I know of one which carries about 500 hundred pounds of ballast on positionable plates underneath the car in order to make weight and have the CG as low as possible along with weight distribution and MOI benefits. I suspect that even with slicks, a BBC Camaro is going to have problems getting the power down, especially on the Crowder big lot now that the asphalt sealing has reduced traction. The car you described sounds very cool but is probably not the fastest CP class legal configuration. It does, however, sound like a fun multi-purpose autocross/drag strip/tire melter.
