At 125 mph it was running about 5300 RPM with the 3.55s...this was with 25 inch-tall tires...This was all done with a STOCK 302 that had a Holley 600/Edelbrock Performer bolted onto it, the car had a SINGLE exhaust pipe at the time AND I was at 6000 feet above sea level where the air is THIN. Now the car has duals and a hot cam, but I am not gonna ever drive it that fast again...
: The car will produce 3.55/2.78ths more torque at the rear wheels at the same engine RPM. Bear in mind that for the most part TORQUE = acceleration. In general, the more torque you produce at the rear wheels, the faster the car will accelerate.
: At 80 mph, you will need 3.55/2.78ths more RPMS to maintain that speed. If you needed 4000 RPMS to maintain 80mph, you'll now need over 5100 RPM!
: Hope this helps.
: : how does having say 3.55's instead of 2.78's (or whatever mavs came stock with) help with street driving??? as far as acceleration goes at least. and then how would it affect driving on i25 at 80mph??
: : thanks again
