I have driven across the country towing a car and on another trip a trailer using what i assume is the stock gearing. You need to use the shifter to keep the revs up on the climbs also helps on the down grades as well . That was ontario to bc . One trip was in the winter don't ask.

So we are thinking of doing a trip to the west coast in our '77 pb. The engine was rebuilt in 2010 by Dick Patterson and I have a Rochester TBI with
the EBL system and spark control. The transmission was replaced at the same time with a rebuilt through DickP as well.
I'm wondering if I need to worry about changing the final drive from the OEM 3.07 to a 3.55 or 3.70. We are not towing anything.
Thoughts?
Thanks
