cam question
Cam, Roller rockers, springs, hardened pushrods, and lifters should all go in if you wanna put in a cam at that mileage.
Edit: also saw that you are wanting to do exhaust at the same time. That's gonna run the price up at least another $500, even for bottom dollar LT's, ORY, and Muffler.

Not spending too much money and camming a car do not go hand it hand. It gets expensive quick when considering the costs of valve springs, locks, retainers, shims, pushrods, rockers, cam, gaskets, fluids, tuning etc. etc. Also, the cc306 is going to need more stall than a 2400, you would need to step up to atleast a 2800 and ideally a 3000+.
