Its been a little while.......
Ok we're dealing with a stock block low compression 360
Maybe AJ will chime in with some calculations
but I'd keep the cam in the 256 degree @.006 range with an Intake close point of less than 55 degrees After Bottom Dead Center (ABDC) @.006 tappet lift to get some dynamic compression
Mike Jones most likely has the best grind in this class 256@.006 with .305 lobe lift- big at .200 asymetrical profile It's his big block motorhome grind and wears really well Mike would pick the exhaust to match your build and exhaust system fill this out and point him at this thread for the flow numbers if using heads that match what I posted above
Street Performance | Jones Cams he can nail your requirements or he'll advise
comp cams has nothing designed for MOPAR- they use their chevy design- thanks comp (you have to go to a 268 comp to get that much lift- it would die)
Howard has a couple example
HM2063164A . .475 .316 252@ 206 @.050 126@200 (verify that may be a BBM number)
Engle
K-52HYD 458" .305" 254° 209°
Lunati may have a Voodo for motor in this range
I saw a
VD 454/475 258/265 112 part number 10230701 (again I do not know if this is a BBM OR SBM number- you would have to ask
I think this cam is one size too big, you would have to ask if they have a shorter MOPAR grind
perhaps our Crower friend could chime in
Most grinders use one size fits all for MOPARS I like to support those that have given Chrysler some individual thought
now if you go to Higher compression pistons- the KB reverse deflector quench designs are best with those heads then everything changes
