Don't know about the cd part of it, but 10007b could have been the predecessor to 100072. 0.480"/0.480", 284/284, 228/228, 112 LSA. Intake closes 41 ABDC @ 0.050" tappet lift. Use with 9.5:1 to 11.0:1 static compression ratio. Operating range 2800-6200.

Don't make any decisions based on what I have posted here. Your cam may not be the same one. If you didn't pull it out of a motor and keep the lifters in the same bores and plan to use the cam back in the same block, it's junk anyway.

My best advice would be to purchase a new cam kit from Summit so that you are certain what you're dealing with, but I'll try to help with what you have.

What's the diameter of the spring pockets in the heads?
Also, using your dial caliper, measure the cam lobes from heel to nose (largest measurement) and also from side to side and deduct. For instance, if the larger measurement was 1.320" and the smaller was 1.000", then deducting would yield a cam lobe lift of 0.320". Multiplying that by a rocker ratio of 1.5 would yield a valve lift of 0.480".
