    Question Cam swap

    I am planning on doing a Cam swap with ls6 heads. I just bought patriot gold springs. I know I should replace my oil pump, timing chain, possibly get a under drive pulley. Is there anything that I am forgetting, chromolly push rods/ hardend push rods, is there anything that I am missing?

    Thanks in advance

    If the heads are coming off, I'd upgrade the lifters. Also look for a good deal on roller rockers.

    Ever time I've looked at roller rockers they are expensive. What kind of lifters, LS-7 lifters?

    I'm an EBay junkie !!! I look for bargains ! I'm running the Comp Cam 850's now, and I've heard good on the LS7's , but haven't tried them.

    The nice thing about he LS-7 is that they are not that expensive. But the last time I looked was about 8 months ago.

    Edit- They are $143 now on WS6store

    I just got done with this swap, Do your self a Favor and get a new Oil Pump O ring while you've got it torn down!!!!! I didnt and was having oil psi issues and drivetrain noises and the o ring was the cause. I had to practically pull everything apart again!!!!

    Good Point ! When I tore down my old motor, the O-ring was broke... Still showed good presure, but it will cause oil foaming issues...
    Uhmm... Wonder if that's what's wrong with my dogs....

    LS7's are the stock replacement LS1 lifter now. No LS1's, only LS7's. If your looking to really upgrade lifters... the caddy lifters are supposed to be top on the line. LS7's would be fine though IMO.

    Im running a Ported LS6 pump. Besides the oring issue which was my own fault, its a great pump.

    when we did my cam swap I pulled the heads and ported and polished them (241 castings) I got a lot of metal out and really opened them up, it made a huge difference. so if the heads you are getting are stock castings I'd say port them before you bolt them on.
    there are a few spots where the water jackets are very close to the runners so you havr to watch what your doing. Bill (bills98ta) brought me a piece of a head cut through the intake runner on one side and cut through the exhaust runner on the other side, so I could see just how far to go on everything. if Bill reminds me I'll get some good picks and post them for everyone before I return it
