WHAT RECOMMENDATION IS THERE FOR A FOUR SPEED MANUEL TRANSMISSION TO GO WITH 235 AND THE ORIGINAL CLOSED DRIVE SHAFT ASSUMING I CAN GET A RING AND PINION FOR A '37 IF I NEED ONE. WANT TO KEEP THE CENTER LINE OF ORIGINAL STICK. WOULD A '37 FOUR SPEED BE BEST OR SOME OTHER TO GO WITH THE 235.
It's not the speed you travel it's the quality of the trip that matters !!!

Two disadvantages to it are that it is a crashbox (no syncros on any gear) and it is very heavy. You could use the later version of the early fourspeed that has syncros on the top three gears. The only close ratio fourspeed I have seen adapted to the torque tube is a Saginaw with a kit from patricks in Casa Grande, Arizona. Its disadvantage is that it is a side shifter, not a top shifter. | | |

The final drive willstill be 1:1. You would also have to change the bellhousing because the 48-55 years used a different bolt pattern for the transmissions.
Your best bet is to lose the torque tube and swap out to an open driveline. It opens up many more possibilities. You don't need to get an overdrive transmission if you find a rear end with high gears like a 3.07 ratio. Many peolpe on the board have swapped T-5 transmissions from an s-10 in there prewar pickup. I believe that is one of the best choices for getting your old truck up to freeway speeds. The t-5 works best with lower gears... 3.55-4.11. Some people run higher gears, some lower. A stock 235 may have trouble pulling a hill with higher gears.

It was available only in 1984-1985 in six cylinder pickups. I would like to find one to have modified for my 1933 Chevy sedan. | | |

Also when you get that T-5 installed you can make our Inliner's Picnic just down the road in Lodi, Sept. 9. Hope to see you there in any case. | | |
