327???

I am pretty sure my cam is wiped out, went to set the valves and the back 2 on the drivers side don't go up as far as the others! so now im stuck looking for a new cam

old cam- http://www.cranecams.com/?show=brows...21&lvl=2&prt=5
motor specs:
327cid
edelbrock petformer intake (not RPM)
holley 650 from a 60's era car
mild stock heads off some other motor cut for 1.94 valves
.525 lift springs (not sure, will call machinist tomarrow)
crap gears
th350 transmission
stock stall
stock rockers
screw-in studs

needs to be a flat-tappet

What would you suggest??

I'd suggest a cam with less duration.

Your old cam requires a high stall converter and 3.73+ gearing to work well in a 327.

something around 206 to 214@.050 would be better.

You'll get a noticable gain in midrange power where you need it the most.

Make sure the engines lifter bores are not glazed, especially the back ones. Use GM EOS in the oil.
Comp Cams's DEH265-10 would work well

or Lunati's new Voodoo series #60100

You'll feel the difference. you were a bit overcammed before.

What's the casting # on the cylinder head?

Comp Cams XE268. 218*/224* duration. Would be great in that motor with some better gears. 3.42s would work well. Even 3.23s shouldn't be terrible. If you have 2.73s or something though, I'd go with the XE256. 212*/218* duration, and it'd be a great cam for all-around.

I have a 350 with an XE274 (224/230) and it works well my 3.23s. Needs a bigger torque converter though, and would work better with deeper gearing.

327???

i have 3.08 gears and am thinking about better ones by next summer, i dont intend on driving it much until then because of winter.
i'll get the casting #'s later, there not very good but there better than what i had by a long shot.

I'd agree with f-bird on the cam suggestion. Something with under 220* duration will work better with the rest of the combo.

Something like the Comp Cams XE262 (218/224* @ .050) would be as big as I'd go. Maybe even the smaller XE256 (212/218* @ .050) would be worth considering.

327???

my machinist suggested the 268 to go with the heads. and as i said i plan on going with better gears soon anyhow and i don't want to buy a new cam with the gears.
i think i'll go with his suggestion and deal with it until i get some better gears, maybe even a cheap stall just so it idles well in gear, not for any major performance gain.
thanks for the advice though

Under FACTORY heads (the guide bosses un-modified for more valve lift), I think the general consensus is that the Xe262 is about as large as you can go and still fit. I've had great experience with the Xe256 in a 305.

You can install whatever springs you want, granted I would HIGHLY recommend installing springs that are designed for the cam, i.e manufacturer matching. Stay away from the generic springs like the "Z-28 Performance Springs" and such. As important as valve springs are, I would stick to the major companies: Comp, Crane, Crower, Isky, etc.

On a side note, even if the spring says .525" lift, that doesn't mean if you change to those springs, you will be able to fit that large of a cam under there. The installed height is what matters. And, from the factory, at around .480" you have to start worrying about the bottom of the retainer slamming into the guide boss - no spring alone can solve that, no matter how good.

327???

i know that, my machinist clearanced the heads for .480
they are good springs too.
