    I will embarss myself and go ahead and ask. If you have a low mileage engine with bolt-ons what damage would it do to install a mild cam without new springs, etc;. The old 283 and 327 cranked out plenty of HP and compression and we swaped the cams out without a thought of toughening-up push rods, springs and the like. Some folks raced them at the track on occasion and the rest of us lopped around town and occasionally tore away from stop lights to impress. Give me your rational/thoughts

    Now your talking my "vintage".....a 3/4 cam ( Thats old school ) will serve you well as you described. That would be under .500 lift over would be called a full cam...match up your lift/duration with your heads and intake flow....tune it and go have some fun....

    If you're going through the trouble of a cam swap, I say get a bigger cam. A smaller cam would almost seem not worth it to me. I understand where you're coming from with saving money on valvetrain components. But while you're in there, you might as well replace the factory stuff with better, stronger aftermarket stuff. But I do have a high-mileage engine, so I don't think like you low-mileage boys.

    stock LS1 springs are barely adequate for a stock cam much less a bigger one....

    Seems to me that once you pull all the lifters, push rods, etc to replace the cam you might as well upgrade all that valve train stuff too.
    The hard part is the cam in and out itself, no?
    Screw the cost, put it on a credit card and transfer the balance to a zero interest. You'll save money in the long run possibly and you'll be worry free.

    Now remember...'bigger' does not always have to mean increased lift. I could have stayed with stock (LS2/LS6) springs with my cam....but chose the safety/reliability of the 918's. And I think I faired quite well In the hp/tq catagory. Im still not sold on all the hype of the super aggressive mondo lift cams. I agree with Sarge...do your homework and have fun.

    You might be able to get away with it but have you ever seen what happens if you drop a valve? It's much more expensive than a set of new springs. Do youself a favor and ask the wife for more money. It's better to be safe than sorry.

    On an LSx engine, lifters can only be removed if the heads are removed.

    I would say valve springs are a must, not like some of the old SBC days. The stock cams in these cars actually have pretty good lift/duration in comparison and it was the beehive valve spring that got GM there. The stock valve springs are "adequate" for the stock cam, and that's all.

    Symmetry is obviously very key though. More lift is always a good thing, provided that the rest of the cam's (and engine's) configuration is designed to work in harmony along with it....
