i am dedicating the time to finish this 6x6 i bought in ny last year. previous owner put in a detroit 353 [104hp]spicer 3053a with .79 overdrive with superlug tires.
i have put on michelin xls. my calculations show speed at 60mph, engine rpm=2351 using 5:83 gears,39.5 inch tires and final trans ratio at .79.
this does not take into account the 1.5 to 1 transfer case. will the 1.5 to 1 transfer case get me down to 2000 rpm at 60 mph? or will i need to upgrade to 4:89s? seems as though the transfer case would reduce my engine rpms by 25%?
