2.77 is too HIGH for towing. I had 2.90's in my 47 Pontiac Streamlimer (Ford
9" truck rear end) and it would "cruise" all day at 100 mph at only 2000 rpm!
However when it came time to pull my 28' SOB (5700# loaded) the motor and
tranny worked very hard. I put in 3.25's and my motor and tranny were much
happier when pulling the trailer, but now the motor has to turn at 3100 rpm
to do 100mph. I've climbed over Loveless Pass (LovelandPass) with this set
up,but still had to work at it. I think 3.50's or 3.70's would be better
still for pulling the BIG hills but my motor would be really spining and
100mph would not be attainable. (note to saftey natzis.....I don't pull my
trailers at 100 mph , but when crossing those deserts not pulling a
trailer....get outta my way Kamakazi approching....{{{>:o)> ) The century
mark was a good refference point to work with when I was playing with my
gears. scince my '47 is also my daily driver the 3.25's pretty much let me
have my cake and eat it too.

the heavier and longer the tow vehicle , the safer it will be. (Logical
thinking)
