    TSP cam package question...

    Hey guys heres the scoop i have been looking in to getting a texas speed camshaft package. The cam i have decided to go with is the tsp 228r (228/228 .588/.588 ) heres my question they have two differant packages both come with your choice of cam ,springs and hardened chromoly pushrods but one comes with comp 918 springs but for a 100 bucks more the other kit has comp prc springs which i guess are the double springs that they say are heavy duty and will support up to .660lift what do you guys think? Btw..any oppions on the lsa they offer..112 or 114? I dont want it too choppy...

    Also..while im in there i will be upgrading to the ls2 timing chain set, and putting in some ls7 lifters. But i am wondering if i should get some upgraded roller rockers or will the stock ones do....word on the street is that i should also replace my oil pump???

    It's just word association for me...someone says "running from the cops" and the first thing that comes to me is CAMARO

    Stock rockers should be fine, you shouldn't pull enough RPM for it to really matter. Thatt cam with an LS6 should make for a great street cam, but it won't pull much past 6,000.

    Comp 918's will be fine. I ran 918's on a 598 lift cam, and never had any problems, so they should be more than fine for you. No need to spend the $$$$ on the PRC's, as they won't do anything special.

    Since you have an auto, I'd suggest 114, it won't be quite as choppy at idle. If you had a manual trans, I'd say go with the 112, since you're feet would be in control of the take off from idle at all times

    everyone has there opinion but mine is an auto with a 112 lsa and it doesnt have any problems at idle plus he has a stall so it wont just walk away that easy.... not too mention u said stock rollers SHOULD be fine... if ur gonna try to do the cheapest cam set up well youll get what u pay for

    Stock rockers WILL be fine. Plenty of people running them with zero problems.

    I wasnt trying to jump you. Just plenty of people running 500 RWHP applications on stock rocker's. Slowass Mr. Luos for example. I had zero thoughts of running aftermarket rockers when doing my mods. By all means, if you want to spend the money, do it. But it is not a necessity.

    114 LSA is nice and subtle, not too obnoxious at all. You can run a beehive spring with no problems on that cam.

    with the cam you posted the the 918's will be fine. also you should get the ported ls6 oil pump and mabe a underdrive pully to. you dont need lifters or rockers with that set up.i got the prc kit from them when i got my cam but i also have a biger cam and heard that there was a lot of bad 918's out but they sead the fixed the issue so you should be just fine with them.

    There was a bad batch of 918's. That was awhile ago, the problem has been fixed.

    The 918's were also upgraded to .625 lift. Thats what I bought and thats what the note posted in them says. Go with a Lingenfelter Oil pump, its $50 dollars cheaper then TSP Ported LS6 pump.

    In order to replace the lifters....the heads have to be removed.


    If you choose the 918's, I would call and make sure they are the new version. There was a bad batch of broken ones a while back. Pretty sure they are mostly weeded out by now, but just be sure.

    For other info... the bad batch had a blue stripe down one side of the springs.

    Let me edit this. From what I have read.... that old style 918's that they were having problems with had a blue stripe down the side.

    This is an article I've seen several times about stock ls lifter ratings above .550.: http://www.gmhightechperformance.com..._arm_type.html



    In a nutshell, they don't recommend it.
