408 Stroker Build Suggestions

get away from cams till you get your compression and heads sorted out
a solid 274 was suggested but you would have to translate into hyd but what furrystump just said EDM solids are more bulletproof
the better the exhaust the less ex duration you will need
once you get the intake duration nailed down based on the Intake close point you need-for dynamic compression and AJ can help you there
and the duration based on the rpm range then you pick the exhaust and the LCA will be a result not an input
there are essentially a half dozen camgrinders to consider for hyd Comp only for the XExxxHL series, Howard, Lunati, Bullet, Engle
once You get close to a spec you can contact them- you are not there yet
Comp has NO Mopar optimised solid cams , add mike jones to the list if solid
and think iron adj rockers anyway
I see the target pistons are 30.5cc show your compression calcs
do your headwork
go to scat and get the compression height of the target piston and figure your deck clerance
