Unknown Camshaft Specs...
I have a Hydraulic flat tappet cam that I am trying to get more details about. It appears to be a custom Comp Cams grind but Im honestly not sure.
The numbers are all scribed onto the front of the cam. I can make some guesses at what it is but would like to build a cam card for it. Just wondering if anyone had some incite... SPEED SAFE, NICK

It’s in there high energy line of lobes.
It’s single pattern and the -4 is 222 duration at .050”. Lobe lift is .309” which would give .464” lift with a 1.5 rocker. I am not 100% sure but I think the 10 is reference to a 110 lobe separation angle. It likely has a power band of 1600 to 5600 would be my bet if I was putting money down! It should be a good Cam in a 9.5 to 1 Comp 389 or 400, or a 9 to 1 comp 421 or 428. For me with a street 455 it’s short on duration and the .525” valve lift I would like to see even with stock iron heads!

Thanks for the info Steve, I was trying to find the link to the comp cams high energy line back in the late 90's but could not find anything. I wasn't sure if the high energy line was around back in 1997 or not... its an old cam... LOL.
Thanks again. SPEED SAFE, NICK

The only reason I was able to provide you with the info I did was because somehow I managed to save my Comp catalog from the late 80s, lol!

I agree, presume it is ground with a 110 LSA.
Unless custom all their High Energy hydraulic cams are ground with a 110 lobe separation. The High Energy 268-4 is listed here on page 11 as lobe number 5212: https://www.compcams.com/lobe-catalog .

The Pontiac Edelbrock cylinder head official "runner volume wars" started with a post on the old Classical Pontiac board in May, 1998. From it the naysayers were off and running, like Paul Revere's famous ride...... yelling the 215 cc runner volume is too big !
Bwahahahahahahaha ! .
