I need to figure out what cam I want to run now. I have 3 solid rollers I can choose from and on large solid flat tappet.

I have a UD grind Solid roller that is Grind number 304 310 R6 and another number of G3984 is on the end. I am trying to find the specs on this cam as I bought it used from a member on here

The UD solid flat tappet is 308-316 F8 and the duration at .050 is 275 and 282. The lift is .649 and .654 with a lobe separation angle of 108.

A lunati SR with 93G1A and 28935 stamped on the end. I lost the information on this cam when my computer died. I also bought it used from a board member.

The final cam is a comp solid roller with grind number of 305-2 305-2 R10. On the Comp cam site the duration is 272 @ .050 with a lift of .622 on a 110 Lobe separation angle.

My heads flow is as follows.

lift......Intake......Exhaust.....%
100....77.1..........62.6.........81.1
200....150.6.........114.6........76
300....204.9.........152.9........74.6
400....250...........177.9........71.1
500....288.2.........200.3........69.5
600....319.1.........226.6........71
700....336.8.........237.7........70.5

Car is a 67 Firebird weighs 3600 lbs and I am running 4.10s now, but my new rearend has 3.73s.
