I have that in my 440, with OOTB Stealths also.
I'd say you're not seeing much difference because in a 500 cubic inch engine that is not really a lot of cam. It probably has a pretty flat torque curve and doesn't need the extra gear.
I had 2.94s in my car when it went together and drove it a bit (4 speed). I put 4.56s in it. (29.5 inch tall tires). The car was a handful with 2.94s, but I can hardly keep up with it with 4.56s, it spins the 9 inch slicks from a roll in 3rd.
Out of curiousity, what valve springs are you running?
When I built the engine it was for a street car so I didn't want a huge cam. It was 9.8 compression with ported 906S. I sold the car and put the engine in the current car with the otb stealths which lowered comp a little ,ROUGHLY 9.5 comp.The valve springs (I think)are still the factory stealths.I cant remember if I swaped springs from the 906s or not. I have no valve float issues, its been to 7,200 rpm but doesn't pick up any et or mph doing so. I shift at roughly 6,000.
