cam cross over

[c.moo]

Was going to get Comp cam XE -274- H 23-224-4 , Now hearing bad things about them going to different cam , The question is what cam would come close or crossover to this cam grind ? The Comp cam was part of engine build combo , want to stick with that combo ,don't want to buy other parts to match different cam , got most parts already for the combo was going to use . Thanks

You should probably give a few cam manufacturers a call....

Just heard from a friend that he had issues with a Lunati flat tappet cam for his built 340. Maybe now all the cam manufacturers are getting bad materials to start with or their quality control has gone away ? China likes to use brand names for inferior products which result in posts like these. I have a bb 440 at the engine builders right now that has a hyd comp cam from 2014 so hopefully no problems with that. Waiting my turn on the dyno - hopefully soon.
My 2 cents anyway

With the matching combo that's a good running cam in a mild street big-block. If that's the one you want, run it...just check it first. ANY aftermarket part--camshafts included--should be inspected and corrected before installing; hopefully your builder knows to do this.
As for finding a similar grind, start researching the cam manufacturers and find one that has similar lobe separation, duration and lift specs, and valve timing. Like '1Wild' says , call them if you're not sure.

Lunati voodoo 703 has a little more lift and less duration then 274xe, 274xe and a voodoo 703 are fast rate cams...comps xe is a chevy grind...voodoo is mopar...springs may interchange but you will have to research it... watch your spring bind height. Fyi.. lunati and comp are owned by the same parent company.

We haven't seen any problems ? and we use/install and Engine Dyno the XE274H Comp regularly ?
What is it you are hearing ?
because I'd love to respond to this folklore ?

Lunati don't make any more power than anything else in the Dyno from what we see in most .842" Lifter Diameter Lobes.... CompCams stuff included.

The only REAL power advantage is the true .904" Diameter Lifter stuff.....or cheating .875" Lifter Diameter rates..... and applying lobe and V/Spring rates that most ninkenpoops aren't capable of maintaining under normal street duty driving.
Nothing wrong with the XE274H Comp
There just aren't any "007" .... Top Secret.... ancient chinese secret **** with Cams... get over it !

LOL.... I don't believe the question was "what is going to be more powerful then a 274. A lot of good people work at comp...a lot of good people work at walmart. Comp has some good products, but bigger companies suffer from quality control being less important then the bottom dollar typically.
Quality wise. I think it's likely that comp gets a bit of a bad wrap just because there are more comps out their there anything else. But...plenty of other good companies to choose from...and I think that is the question being asked and what matches up size/fit wise from other companies.

The sharp edge radiates off the side of the Lobe ..... which IMO is not a 'defect' ?
Maybe take a small file and de-burr the lobe edges if worried about it ?
Common part of DIY inspection of parts prior to assembly ?

How much you wish to bet 99% of people just "line up the dots" on their Timing Chain when installing ? and never check the degree on their Cam installation.
Yet THAT is not considered a "defect" in Labor ?

That’s a new one on me....... the cam has to pass the lint snag test.

I think the problems with this cam would be a bigger issue myself......
Multiple manufacturing defects on this one(not related to the casting itself):

Here’s another ugly one..... from another highly respected cam supplier that isn’t part of the Comp group:

I can't remember the last time we had a Flat Tappet Cam that passed a lint snag test ?
Just say'in...
lotsa times we've needed to take a cartridge roll and de-burr a lobe edge or two... three, whatever..... and from many suppliers ?

How many Flat Tappet Cam core suppliers are left ?
If there are bad/defective metallurgy 'cores' out there ? I don't believe any particular company has a lock on the good stuff.... they go everywhere.
