I’m looking at a 88 R-690 tri axle dump it has a em6-300L with a 2070 trans and 5:73 gears. Everything about the truck is perfect for wat I want except the top speed of 59mph. I have another 89 Mack that has 4:42 gears if I put those carriers in would it sacrifice too much power? I don’t mind being under powered but I don’t want it to struggle to go. Or is there another route I could go? I really need it to go 65mph. Could I get away with 24 talls and turning it up to 2400rpm? Thank you all for your help in advance! I know this ? Has been brought up mor than once in here. Pick for reference.
