The 4-spd is out of a '46 1/2 ton. I was told that the 4-spd was an option for the half ton trucks, standard in 3/4 ton trucks. Pretty much a newbie to this stuff so I don't know this as fact.
After purchasing this truck I drove it maybe 20-30 miles before begining the restoration. I just felt it was geared way to 'tall' for my intentions. ie; 1st gear 0-30 mph, 2nd gear 5-35 mpg, 3rd gear 10-40 mph.
When puttering around country back roads there just did not seem to be a 'good' gear to be in. The engine would be lugging, the truck lurching and ground spd way to fast even in 1st gear. Just got it in my head to put in the 4-sp. to gear it down a bit to make it more 'drivable' for my use.
Your mentioning of the un-syncronized 4-spd does jog my memory in regards to hearing that before. I DON'T want an unsyncronized trans! My two young (teenage) sons will be driving this as well. It is our project truck we are building together and it will be handed down to them. It is such a pleasure to work on it with them. Gives the ol'man a chance to re-live his younger days when while still in High School I street/rat rodded a '45 Ford 1/2 ton. I dropped a 413 Merc. engine with a T-10 Muncie in it. :)
Woo-Hoo!! What a ride!
I'm living proof that God watches over small children and fools. :)
I will get into this 4-spd to check on that syncro thing..........
Thanks for the heads up!
