Cams How do you choose one?

Nothing wrong with crane quality
and I like TQ's
278 crane degrees is more like a 270 comp/ lunati/ howard/ etc so do not translate 278 crane to 280 comp a XE275HL comp is going to be a much bigger cam
IMHO still too big seat duation for an 8:1 motor
but depends on how you would like to drive it- easy or hot rod
how much lift will your valvetrain take (keeper to seal) are you stock
is your valve job good for more than .450 lift- multi angle and blended down the bowl?
If so get valve open- hold it open at whatever lift you can handle- close it Keep it simple no reason for a lot of lift if your heads do not flow at more lift
There is no need of almost half inch lift on the exhaust with stock valve job- uncut valve guides- aftermarket stem seals- BVVC of your clearances at that lift
I've been campaigning against extra long exhaust duration but in the case of stock exhaust ports and stock HP manifolds the 12 degree spread should be ok
Let's see what Jones says-- I've been wrong before
Jones Hyd compared to DC 260
461 (.305 lobe) [email protected] 202 @.050 120@200 64@275 Jones Special
430 212@050 115@200 [email protected] DC 260 is about 10 degrees bigger than the Jones on the seat but Jones is 50% bigger where it counts DC260 is measured by MOPAR method not .004 more like .008
