Thanks Tim, my 235 is a 59’ from a car with hydraulic lifters, 3 “on the tree” transmission with the original 4:11 torque tube. It seems to me that with a lower ratio on a SM420 (3.58), it would be a better transmission for changing to 3.55 or higher rear gears than the 3-speed with a starting (1st gear) ratio of 2.94.
I have safety issues to deal with first, wandering steering (another post) inadequate brakes, (already looked at rears, need to look at front), and seat belts (feel naked without them). Got to tackle those first. At this point, I can’t even imagine this truck going any faster than 45 MPH, and at that speed I felt unsafe.
And I agree that I need to fix what I have prior to making improvements. So, I’m really just looking at future options. Who knows, I may like what I already have.
