which is a better cam Xtreme Energy 274h or crane z cam .473 .486 ? and do they make around the same power ? and is anyone running a z cam? i know people are running the xe one.

 

Which z-cam are you comparing to the xe274h?

Be very careful comparing, crane measures advertised at .004" lift, vs .006" lift. So if the two companies ground the EXACT SAME CAM and handed it to you, Crane would say it's a few degrees larger (advertised), even though they are identical.
So ignore advertised altogether.

Use duration @.050", and lift. In my personal digging for facts experience, it seems comp seems to get more lift out of less duration than Crane has. Maybe that means the Crane cam will last longer, who knows. Lift is power though.
Lunati's voodoo lineup is even more aggressive still.

I think F-bird'88 is a fan of Crane cams. Most of the others here are comp fans.

You already have the Z cam though, so why does this even matter?

 

bc its still in the box i aint got my block back yet i get it back friday so i may take back the cam back to summit bc i read something in an article on my trick flow heads and xe 274h cam in a 383 making 455 horsepower just asking around more

 

Assuming your crane cam is in the range of 230/236* at .050", it probably wouldn't make much difference either way.
I think the compxe274 is like .490"/.501" right?

So which crane cam is it then?

 

its 224/230 at 50 and the 274 is .486 .490

 

Ok, so after digging through your garbled info that you gave in weird order, you have a

Crane Z cam
224/230
.473 .486"

And you're thinking about getting the Compxe274
230/236
.486 .490"

That crane cam is very similar to the compxe268. So you're thinking about going up one step, to the xe274 (or the crane equivalent, if you wanted to).

The comp cam is slightly bigger and will make a bit more power. Not much though, they're pretty close.

 

in ur opion what would u do ? andhow much horsepower is a lil like 15 maybe

 

You only have 2200RPM stall, and it's a 350 right?
Leave it. The xe274 would kill a bit of low end torque. The HP diff is small, 10HP maybe. I think you're in a good place now.

 

yea bored 40 over but the z cam 2200 to 6400 where they say the xe274 is 1800 to 6000

 

bored .040" over doesn't mean squat.
The RPM rating is marketing, nothing more. Specs tell the story.
They have the same 110LSA right? Then the duration @.050" will tell you where they'll make power.
The xe274 is more like 2600-6000RPM, and the zcam will be more like 2200-5600RPM or so.

 

how much horsepower should i get from that set up just a guess

 

lol ur right it dont mean squat. that just why i was say it was a 357. and thanks for the help

 

I would invest in a high stall converter. Both/either cam will work a heck of a lot better with a 3000/3500stall 10" converter.
