Xtreme Energy Comp Cam Dissappointment for 440

[hawaiico]

I installed a comp cam Xtreme Engergy PN 21-222-4;
Duration @.050 218/224, 110 lobe separation, .462 intake & .470 exhaust gross valve lift.
Flat tappets did not turn and lifter noise is evident (less than 2000 miles).  This happened twice even though dyno'd & run in properly.  Factory was vague when asked if this was a problem with the their product.  I believe engine will perform better with a different cam spec.  GOT ANY IDEAS?
Rebuild details are:
440 rotating units balanced
Weiand Action+plus
Road Demon 725 carb
3:23 limited slip ratio w/ P275-60R-15 tires
Keith Black Hypereutectic Piston 9.23:1 compression
452 heads bowl ported w/2.14"-1.81" valves

Thanks, Outback Bob SASS #74180

Bob, what's the stall speed of your torque converter ? That cam is more suited to an RV/Towing application. 

Engle makes some nice hydraulic profiles that run strong. Not a fan of that carb either....a Proform 750dp would be a big step in the right direction.

Thanks for the response.  The convertor is 500 to 800 over stock.  So I'm guessing 2300 to 2600 stall rpm?  This is a lame cam, just got to go!  I'm pulling the engine and going to swap out the cam before Kool April Nites in Redding CA.  I need to select a new cam soon.
thanks,

The carb has been a pain, loose and leaky.

I like the 268* VooDoo cam for your combo....this should liven things up under the hood !

I have virtually the same combo as you.  Only a BIGS stage 5 750 dp with a Street Donimator and around 2500-2800 stall.  I have been running the 60303 Voodoo cam for a few months now.  No complaints and feels pretty lively.  I have thoughts that I may have gone a little small on the cam but its better not to over cam.

Eagle made a recommendation to use their K60 hydraulic;  .534 lift with a 238 duration.  Any comments on this cam?
Thanks,

That's too much cam for a 2500 stall and 3.23 gears, inmo.

238 is too big for a heavy car...won't fall out of a tree without more stall and gear.

The crower 32243 226/236 @ .050 is a great grind for your Combo, if your Daring and are definately running headers their 231/240 @.050 is a little bit hotter but not too much for your converter. Crowers just flat out work great in BB mopars.

Hughes/Engle used to sell a 230/230 Duration .515 lift that was a pretty sweet 440 cam, seemed mild but had plenty of punch fromthe upper bottom on up.

[Rolling_Thunder]

K60 is too large in my opinion as well...

I would say a K56/K58 on a 110 LSA   

[firefighter3931]

Yep, that would be my choice in an Engle cam....or for an off the shelf grind, the 268* VooDoo grind which is almost identical to the Crower 32243 that Streetwize suggested above. The Voodoo has similar .050 duration/lift to the Crower but less seat timing which means better idle/street mannners. Any of these would be a step in the right direction vs. the current cam, inmo.

Ron is this the cam U recommend for my 440?  http://store.summitracing.com/partdetail.asp?part=LUN%2D60302LK&autoview=sku

Bob, the cam i suggested is the next biggest grind than the one above. The cam i linked to earlier in this thread is the right profile but the wrong application (smallblock). Sorry for the wrong part number....my bad ! 


Ok, here is the correct 268* Voodoo cam for your 440.

This cam is a 3 bolt core so if your current cam is a single bolt you will need to change the timing chain set. I'm not sure what valvesprings you have now but if they are the Comp # 911's then they will work fine with this cam.  Of course you will also need a new set of lifters with the new cam and they are available as a package (Cam/Lifters) as well.

I've been meaning to try out one of the 'Ultradyne Harolds' Lunati's, the Voodoos were Harolds contribution before he packed his bags.

From a marketing perspective I think Holley (that owned Lunati) kinda shot themselves inthe foot with the 3 bolt juicers....most people running mild to mildly hot Hydraulics either already bought or prefer to run the old single bolt T/C set. I like the idea of running the Lunati (the old ones like the 30307 240/250 @.050 that I used to run) were very good but always ran a little bigger than advertised, I think their stuff was a little too hairy for some folks.

Antother option is to call Tim Goolsby at Bullet and have him grind you a custom off the old Ultradyne blanks, Tim used to be Harold's right hand man at U/D way back when.

The old UD 231/239 @.050 is a screamer on a tight 108 center in at 104, that big old Charger would really walk the dog with that stick in there. use the "Late" (last U/D design) intake lobe combined with the older/slower Exhaust ramp. What that cam will do is it will sound absolutely badazz nasty at idle but it'll have great drivability in a 440 and make mad torque and great overall power...with the right carb tune your 3.23's will actually feel more like 3.91's in terms of kick down and roll on power, fact of business

I don't play much with hydraulic F/T's any more (In the past few years I've built 100% rollers) but I always ran custom stuff and I've always gotten just what I wanted from both UD and Comp

Thanks for all the input!

Engle suggests this combination:

K-56/58 w/110 lobe = 224/230
$154

K-56HYD      .538"   .504"   .336"   268°   224°   140°   
K-58HYD      .549"   .514"   .343"   276°   230°   148°   

Any comments?
Thanks Bob

Yep, that's a very good option as well.

Hawaiico you mentioned that you had problems with the lifters not turning, one thing you might try when you install your cam and lifters is make sure your lifter bores allow the lifters to turn freely and install the cam and lifters dry, put a mark on each of the lifters and turn the engine over, watch the lifters and they should spin freely and if they don't take and swap lifters around until hopefully all of them spin and then of course lube everything back up with proper cam lube and put together. We did this on a couple of small block chevys and it seemed to work but then again this prodecure might be like blowing smoke up somewhere, it way work or it might be a waste of time.

Just a suggestion,
Kevin
