I have been restoring a 3/4 ton, 55 1st with the original 270 (rebuilt), the original SM420 transmission and new 3.90 rear gears. At first this was just to be a hobby truck, fun to drive, but also would be used for truck stuff. I have recently bought a pretty large "box trailer" setup for vending and had hoped to use this truck to tow it.
I am now shaken in my faith that this truck, with the 270 & SM420 will be capable of towing this trailer. The trailer is a tandem axel (3500lb each) trailer that will probably come in weighing 6000 - 6500lbs. Should I expect this truck to tow that load effectively?
This is a new business that I will be starting and I am investing $ right now in setting up this truck with the 270. If it will not do the job, then I need to stop spending the $ on the 270 and go with something that will.
So….I need some advice. First – will the 270 and SM420 cut it. If yes – GREAT! If not – then what would make for a good tow motor and transmission combo? If I have to go with a new motor and transmission, I am willing to stray from original – however I would MUCH prefer to hear that this 270 will do the job like the champ I believe it is.
Thank you all very much for all the advice you have already given. I really appreciate your wealth of knowledge and I hope that I can learn from you and share with others as I get more experienced.
God Bless! - Tom
