Do it. Its Summit price is $200.

You can use stock springs. If the exhausts have rotaters, remove them and the springs and replace with the same stuff that's on the intake.
318 roller cam springs like I found on my '86 Fifth 318 are a little stiffer than the stock springs and would be a decent upgrade.
Specs are 204/204 @ 50 lift, 110LSA
0.420 lift.
It's really really close to the old Comp 252H grind, they claimed 0.425 lift otherwise everything else's the same.

I bought one several years ago to use in a 318 and have never gotten around to using it.

It's one step bigger than a stock 360 cam and makes a really nice cam for a 318. It'll get more power from the 360 with excellent manners.
