My 350/700r4 with a 3:50 gear and a 27" tire runs 1900 RPMs at 60 mph and delivers 21 mpg.
The 700R4 has a super low 1st gear and will really help launch your 3100 lb. mopar. However, mine seems to be building an excessive amount of internal pressure at hwy speeds and often pukes out the overflow. This condition also puts a lot of pressure on the rear seal (new) and pan gasket (new) and puddles my garage floor after its been run.
Any ideas on this problem Crosley??
