Gear change with w2 408

2.94 should be perfect for a 408, but maybe your cam and 28" tires are not a good match
I like 3.23's in a well tuned stock 340 with stock size tires and converter.Cruises on the highway at lo rpm and blows the tires out easily at lo speeds. Going to try 2.94's...I tried and did not like 3.9's and 3.5's
