    ahhh yes. Forgot the timing chain. So thats pretty much it right. Nice break in with some good lube and it should be all good ?

    depends...how big is the new cam? what engine? what's in it now?

    If it's not much of a change, then you should be fine. But if you're putting in a much bigger cam you might need to do more stuff, like machine the ends of the guides, check piston/valve clearance, degree it, change rockers/pushrods, etc.

    you may need to run recessed pistons so the valves don't hit

    Ok, asking is a good way to learn :)

    Also if you put in a longer duration cam, you usually need to change things in the car to work with it. Adding headers, maybe more carburation, and changing the gearing in the transmission/rearend to allow the engine to run at higher rpm. After all that's what a cam change is usually done for..to raise the RPM band that the engine makes power, because this increases power (hp = rpm x torque/5252)

    see I snuck in a math lesson too

    what engine and cam are you going with?
     
  15. What they said....also new valve stem seals, and valve keepers. Do your research on the proper lift, duration etc., understand other things come into play-like vacuum for automatic transmission, power brakes, if you have.

    Since I just went through all of this, I highly suggest calling Iskendarians tech line and reading their .pdf on cam installations.

    One thing you must consider is the stall of your torque convertor and whether you are running AC. Your idle will make you miserable if you have a tight convertor or AC if running too much cam. I picked a Summit 1103 cam for these reasons, with new hardened pushrods, new lifters, new springs, new seals, keepers, locks, and a gear drive. The timing chain on the motor was tight, however it was not a true roller. The cam usually comes with lube for the lobes, and a zinc additive is a good idea for the oil. Valvoline racing oil has higher zinc than most.
