252+258= 510
510/4 = 127.5
127.5- 112 = 15.5
15.5* 2 = 31 degrees of overlap??
Is that correct?

A few questions for you:
- What brand Cats
- Was it a stock untouched LS7 intake, no porting?
- How can that cam pass emissions with so much valve overlap?
236 + 240 = 476
476 / 4 = 119
119 - 116 = 3
3 * 2 = 6 degrees of overlap

You use advertised duration not .050 #'s to calculate overlap. Cams have a hell of alot more overlap than 6 degrees. my 222/230 112lsa cam is 284/292 adv. duration with a 112 lsa and it has 64 degrees of overlap.

I will post numbers when mine is done. The prototype motor had a curve very similar to the thread starter's posted dyno chart... just much nearer the top of the graph paper
The key components are "ported heads" and "monster cam"
