350 Upgrade Help/Suggestions

[Rogue67]

I have stock gears In the rear but looking at 3.83 gears in the near future, and with the converter I have a 2500 stall I'm going to throw in. Now wouldn't this cam theoretically give less sound/power since the lift and duration are different? ( I don't now much about cam specs and info) what is the benefit of having the intake/exhaust different? I have been looking into vortex heads but if I was to upgrade heads it would be too aluminum so I'm kind of skeptical on spending the money now when I really want aluminum.



Thanks for all the insight and suggestions
