Cam Lobe ?

I believe it's a custom grind (11-000-9) SN# 1 2903-06 Grind CB 4624B/1267B R10

R279/286 R110

The intake lobe is a TK Series, which is pretty aggressive. The exhaust lobe 1267B I could not find in your online lobe catalog. Can you provide some details about this exhaust lobe please.

Both lobes indicate being run with 0.018 & 0.022 lash, so these should be the newer type lobe design as compared to the older larger lash type rollers.

This is for a BBC drag race motor.

Thx

That lobe is 325 @ .020, of course you know it is 286 @ .050 and the lift is .431. It is 198 @ .200 and the recommended lash on the lobe ID that I have is showing .028. The design was updated in 2000, so it is an older design. I can't find it in any of my lobe catalogs, but it is in our computer, so I would have to say it is an older catalog cam lobe.

Thanks for the quick response. I'll go back a check the cam card (It's not handy right now) to confirm the lash. If the lash on the card states something other than the 0.028 you're seeing in your records, I suspect the card will be followed.

No problem, I am glad I could help.
