2.76 open to 3.55 Sure Grip...expectations too high?

I will say that I noticed some difference, but it doesn't feel like I'm driving a completely different car, as some folks had suggested to me when I told them I was doing the swap. The car has a 318, 4bbl, mild cam, headers, 904. The only thing I wish I upgraded that I didn't when the engine was out, was the converter.

The speedo is broken, so all I really have to go by is how my *** feels in the seat.

I may take a look at the timing to double check where I'm at, but it seemed happiest around 14 initial and 32-34 total. Should the timing be adjusted with different gearing?
