418 W2 Stroker - Dazed and Confused

I've been searching and reading old threads hoping to find the right advice for my build. I am down to camshaft selection now and asking for help. Here's what is going on with the stroker..........
1973 340 block, .040 over, Eagle forged crank,
Ross forged pistons, 10:5 to 1
W2 Econo Heads (long valve), ported, flow 302 at peak,
73cc combustion chmbr
W2 Single Plane Intake
Edelbrock 750cfm carb
TTI W2 Headers
Currently 3:55 gear ratio, 4-speed, no power brakes

Realize I may need to go 3.90 or 4.11 on the gears, but I want a serious sounding cam that wont give up too much at lower rpm. Is this even possible?
Would like a hydraulic roller, looking at Crane HR238/365 with 238/246 duration, 292/300 adv duration, 548/558 l;ift.

I think I am over-camming but cant help myself.
Any input would be appreciated!
