Is this cam to much for a stock engine?

Get something in the 210-220 at .050" range with .455" - .480" lift. If the manufacturer says to change springs, change springs.
This will make that 360 a real street monster with stock stuff.
It will be fun to drive and dust most others on the road while maintaining good street manners.

With that said, this cam is a little hotter than what I just suggested and is probably the limit on what you should run on your stock stuff:

The Bracket Master II camshaft is the logical choice for some high performance street machines, off-road jeeps and mild performance Bracket racing applications. They provide excellent power over a broad power band and give that lopey idle so many people like.Hydraulic, fair idle. Good cam for high performance street applications with good low end and mid range torque and horsepower. Needs headers, 9:1 compression ratio and 3.50 gearing.

These cams are from a cam & lifter kit where the lifters were removed. Cam is stamped with part number on end. White boxed.

Made in USA.

The recommended springs are only 100 pounds on the seat.
You would still have to buy a quality set of lifters.
