So with you guys saying my mph doesn't match the rpm with my 3.55 gears. Is it the cam causing issues with the torque converter causing it to slip since it's built more for top end?
no
get your tire dia plug that into the calc to find out your gears
27 tall tire 50 mph@3000=4.56 gear
26 tire 50@3000=4.30 gear
trans could be slipping or the converter could be junk or your spedo is off
you need to work the problem
verify mph@50
verify tach isnt junk
verify trans isnt slipping
verify proper kickdown
verify gear ratio
verify tire size
checking cam is about 7th on the list
nice looking ride
