    expected horse power out of a cam?

    How much power can you get out of a cam that you guys would reccomend. the engine is stock so thats why im asking what kind of RWHP can you get with a cam and tune only. I plan on getting better valve springs and pushrods when spring rolls by so thats not an issue.
    oh and my muffler is a magnaflow.........
    we are putting this cam in my friends car and thats all hes doing so I cant help him with the info.

    with most cams you can expect a 50 to 80 RWHP increase. It depends on the size of the cam, and mods you already have. Most guys out there do heads along with the cam. This helps a lot! a lot! If you're planning on doing just cam, springs and pushrods you'll probably see about a 50-60 RWHP gain. If you get your stockers ported and polished it will help too. Cams aren't the only thing that makes cars haul ass, pay attention to the little things like rocker rollers, stem seals, oil pumps, timing chain, etc. When it comes down to it, these are the difference makers, not the cam, anyone can throw in a cam and run decent. Just my two cents.

    Oh! One more thing, what plans do you have for the car? Daily driver, cruiser? This info will help when asking what cam we would suggest.

    Those numbers are the very high side of things.... 30-55rwhp is the average with not that many at all breaking the 50 mark.

    To the original poster.... if your car is all stock (no headers/lid) then save your money; the headers and lid will make more power. I say this because no one with a stock exhaust is gonna pick up 40rwhp just changing a cam. Might not get more than 20.

    The Thunder Racing CheaTR cam is designed for stock exhaust with its much longer exhaust duration, and will get you 40 hp. However, it has aggressive cam lobes and new springs and pushrods are a must when you install it.

    IMO.... If your changing a stock cam, Push rods, springs, retainers and retainers are a..... Cam set-up. I wouldnt install even a "mild" 224 with out those upgrades.

    Why would you want to "baby" the car after putting a cam in it?

    That just seems backwards to me, but good luck with the install.

    you can very easily fuck your engine up.
    rebuilding an ls1 is not cheap.

    This is stupid unless you are trashing this engine on purpose, listen to the advice that you asked for. A broken spring or other valve hardware failure can easily lead to a dropped valve. Care to wager what happens when you float those valves from weak springs at 5K RPMs and a valve finds it's way into a cylinder with a rapidly moving piston?

    If you already put the cam in, don't start it. Don't run it until you change the springs.

    Listen to what Frost is saying here. You could get away with starting and idling depending on the cam size, but it will run like poo and you will have to rev it to keep it running and one thing will lead to another and the next thing you know you are doing a ricer rev banging off the rev limiter and BANG........ your engine is dead.





    Well, maybe!

    Frost, I think he just meant that he wasn't paying for labor as he was putting it in himself. At least that what I gathered from previous post, but I do agree. I had to buy all the parts for my set up in a span of a year. Yes it is hard but well worth it when it comes together.
