430 HP is not a lot of power. The 904 would have worked OK for your application. The Dana 60 is also overkill IMO compared to a 8 3/4. Your fish will be lotsa happy with a good running stroker.
Ya, I realize that the Dana was going overboard, but it was my cheapest route to a 4.10 posi to replace my noisy 7&1/4. - Plus it gets the car a little closer to resembling a factory Hemi Barracuda. My first choice would have been an 8&3/4 but I didn't want to spend what people were asking for them. Most that I'd found were either single tracs, needing rebuilt, needing narrowed, or a gear change. The Dana cost me $300 before I had it narrowed and disc brakes added. I figured I'd have spent more on an 8&3/4 to start with and still had the same expenses narrowing it and changing brakes. - Plus I would most likely have had to shell out for gears.
The extra horses it takes to drive that Dana shouldn't kill it for the street.
