recommended cam for a 5.9 magnum?

Roller of course.....Really need more info to make an educated guess,
Intake manifold? single or dual plane advertised power sweet spot
exhaust headers/manifolds?
carb cfm, vac or mechanical secondaries?
rear end gears?
converter stall speed?
tire size?
distributor stock or aftermarket?
heads 1.92 or 2.02 bowl work or ported?
compression ratio?
power adder nitrous/turbo/supercharger?

good place to start to get a general idea go to compcams.com and download camquest6

I'll fill in what i can:
Intake manifold? dual plane air gap knock off, 1500-6500 range

exhaust headers/manifolds? hedman long tubes(may go to the tight tube if i bang these up too much)

carb cfm, vac or mechanical secondaries? 600cfm edelbrock 1406 w/ electric choke. Although i may need to go to a bigger carb?

rear end gears? 3.55

converter stall speed? As far as i know its a stock stall converter. Staying that way until i get together an A500. Then i'd probably copy the other guys here that have a 2800 stall

tire size? 245/45/17s. May get some drag wheels in the future.

distributor stock or aftermarket? stock

heads 1.92 or 2.02 bowl work or ported? 1.92s ran as they're cast.

compression ratio?whatever the stock magnum 5.9 is

power adder nitrous/turbo/supercharger? plan to run a nitrous kit at some point
