sm465 to th350 swap
Hello I have a 1969 K10 shortbed with the SM465 / NP205 transmission transfercase combo. I have recently developed a high pitch bearing failure sound coming through the shifters into the cab. I have a TH350/NP205 that I could swap over to. My questions is if anyone out there has a TH350 with 3.73 gears and 33" tires. The 4 speed that's in the truck now is pretty lunky to drive (less than ideal 2nd and 3rd gear ratios). Will the TH350 1st and 2nd gear ratios get the truck moving a little better? How is the highway? Anyone who has a driveline combination out there I would appreciate to hear your input. Thanks
