camshaft war!!

Ok, not really, but it's hard decision for me here, my chioces are A)$255 comp cams k cam kit that comes with camshaft, lifters, timing chains/gears, valve springs, spring retainers and locks, valve seals+$17 mr gasket gasket kit... or B)$78 crane cam energizer cam and lifters+$60? valve springs(I don't know which sizes though), $53 mr gasket gasket and timing chain set... now the latter is obviously cheaper but do I need those retainers/seals/locks, and is the comp cams 260h worth the extra dough, or would I be better getting the timing chain seperate, some say they'll add some hp...

Re: camshaft war!! (szercer)

I bought a Comp XE262 cam and lifter kit a few months ago. Had the same questions. I decided that I could pick the springs and timing gear myself. Looking back on it I think that I would get the spring recommended by Comp. rather than another brand. For my timing chain I got a double row Cloyes. Either will last as long as I'm going to drive the car and one will not work noticeably better than the other.

Re: camshaft war!! (StrayDog)

StrayDog-
I'm using a G-Tech to check my 0 to 60 times and only do one shift. The engine seems to prefer to go to 5200 RPM. Higher RPM = slower 0-60. Lower RPM= slightly slower 0-60. Running the engine to 4500 RPM and shifting makes faster speeds than running it to 5800. These numbers have not been fully firmed up as I'm doing carb. adjustments with every pass so the end result may be differant yet.
Don't know how, if at all, this will relate to a big block.

Re: camshaft war!! (szercer)

Get someone to dyno the two cams - then you'll know the difference if any.
I've looked at these two possibilities too - wondered what the differences
were in the engine.

Which cam's were you looking at ? 260? 268? 10172 (crane?)

Re: camshaft war!! (1979toy)

I just ordered the comp cam xe 262 K-kit... damn expensive but it comes with everything you need... I'd stick to the kit because everything works together and if you go mixing and mathcing parts up it might not work as well as it should
