The M4-F cam was made to 'upgrade' the 40s engines in the 50s. By 1955 the 235 engines stock had more horsepower than the (upgraded) 40s ones and the 261 even more.
The 54 Vette cam had different specs, but used Hyd. lifters where the M4-F was/is a solid lifter camshaft. Totally different usage and MFG for that Corvette only (one time).
You don't have to actually 'use' a product to know what it does and doesn't do.
If you want to upgrade a 55 or newer 235 or 261 CID engine you need a F-290 or F-298 unit. These are used for Hot Rods & racing and not really good for "daily driving" etc.
It's just that simple!
