Cams How do you choose one?

Great Thread
First reread post 14 and 19
then
"Seems like the recommended Bullet cam specs are very similar to the Summit 1789 , but with a hair more exhaust duration." post 71 Bullet is a much bigger cam- way too much duration for a low compression build- see my post above
BULLET, COMP, HOWARD, LUNATI measure their seat duration (.006) different than SUMMIT, CRANE, ELGIN (.004)
MOPAR Stock and MOPAR PERFORMANCE (and ENGLE) are different again somewhere around .008
Perhaps Crower could say where Crower measures theirs but I guarantee that a 267 Crower is bigger than a 276 Summit or Crane
and much bigger than the suggested 268 or 272 Cranes
Bullet and Howard (and Crower) need to know that you need a cam from their .904 list
why- to get a decent area under the curve while keeping great dynamic compression
BTW these are not Bracket Racer grinds you get more area due to the bigger lifter not because of a more radical grind
Have the machine shop cut the guides for a half inch lift will give you much more flexability also for Viton seals at the same time
Summit Cams were ground by Crane's detroit subsidiary- Even Crane Cams were mostly not ground in florida (same with all the big camgrinders)
let us know if you are going to change the heads/ compression- whole new ball game
No comp cams smaller than XE275HL you leave torque on the table The duration suggested are fine- it's the area under the lift curve that sucks
