Comp Cams

Hey guys, has anyone used comp cams extreme energy hydraulic roller big block cam. I am considering the extreme energy or the new thumper series. The new cams have good rpm range but the lift looks low compared to older camshaft designs. Under 600. I guess with technology you dont need big lift to make power.

Re: Comp Cams

I'm gonna take the plunge and use a COMP Hyd Roller cam in my 1969 427. The cam I am looking at is part# CCA-11-443-8. My engine builder used this cam on another 427 he built over the winter for a customer. When he ran it on the dyno it made over 540 hp with 9.1:1 compression. Idle was choppy but nice.
He also said this cam will make more power than the Thumper cam.

Re: Comp Cams

Thats funny because that is the same cam I was considering for my 427. It was between that xtreme energy and the thumper. I talked to a comp cam rep at an expo show and he stated that even with the low lift numbers it was an excellent street cam and would make good power.

Yep. I agree. At least do a search on Comp Cam failures. You will rethink using any of thier parts.

Re: Comp Cams

Dont be afraid to use any brand name cam. I personally do run a Lunati Voodoo (UD designed), but Cammotion, Bullet, Crane, Lunati, and Comp all make hood stuff. If you go with Comp spend the extra couple of bucks and make sure you get the a -9 (steel)core rather than he -8 (cast iron) and you'll be fine.

If you have time you should get in touch with Christ Straub as he will design a custom profile that matches your combo for even more power.

Re: Comp Cams

Here's a couple links where you can read about how bad CompCams tech support screwed over a guy I know.

Their tech support line told him to change the gear on his distributor to the wrong one. The cast gear shredded and caused a catastrophic failure of the engine. Cost him about $4,000.
http://www.ffcobra.com/forums/showthread.php?t=3092


Thread with CompCams final offer. Although they admitted to the error, their offer was to pay for the cam.
http://www.ffcobra.com/forums/showthread.php?t=179426

Based on his experience alone, I won't buy anything from them. He's compiling contact info of others who's received the same advice (advice they still give out today knowing of the problem) and he's trying to find a lawyer to represent them as a class.

I don't know if the gear problem is a Ford thing only.

Re: Comp cams failure.

--------------------------------------------------------------------------------

Carl...Mine was assembled by a reputable engine shop here. It was broken in on the dyno. Used Rotella with EOS. Had a total of 6 hours on the dyno due to different header sizes, carbs, and ignition systems being tested. At about 50 street miles, one of the Comp lifters came apart at the seam. It destroyed the cam and broke a hole in the block. We sent the cam and lifters back to Comp. Turns out the lifter was Chinese made. Thier tech man "Red" said the cam went bad first due to it being installed too far in the block. I found that real hard to believe and asked him to put that in writing for me. He refused to do that.

This is a summary from a post a while back. Like I said, do a search on Google. Type in "Comp cam failure".

Question Re: Comp Cams

Whatever happened to the thread where somebody was trying to compile hardness data on cam failures a while back?

May even be a couple to three years ago?

Is it here or over at Big Brother, (aka, Team Chevelle??)....

B/c it would be GREAT to keep threads like this linked in a STICKY!!!
