Grumpy I will take your selection of cam sheets please and Brian just the one Isky or any others you want?
Use the Isky 272/282 Cam from me to compare next to all others John.
Dynamic compression way safe with his engine combo.
7.0:1 dynamic.
Seen 540 Hp peak at 6500 rpm.
Torque band good.
Will run on 87 octane. Need more 89-93 can be used.
 
Its going to get confusing John.
Make runs with open headers.

A key made for each.
Or tag for cams.

Narrate each optional
 
Its Like The Jegs Engine Master Contest.
John Kasse is famous for winning it.

One year he built a Pontiac 455.
Blew all away.
Took home $250,000 Cash.
 
I have noticed that the custom cam guys are cutting way back on the exhaust lift. I have a Mike Jones cam the same way in a 496. The specs of that Smith cam are the same concept. I have also noticed Chris Straub is grinding this way also. What gives? Is it that the exhaust ports on these newer heads are more efficient? I really appreciate all you guys times and value your opinion. I have enjoyed reading through Rick's massive forum. Awesome photos and the level of attention and detail are immpecable. I have never been part of a discussion to this level and had as many respectful disagreements and encouraging dialog. It's a breathe of fresh air. Kudos to you all. I look forward to seeing some more graphs and responses. Thank you kindly for the time you have all taken, much appreciated.
