driveshaft cut
Hey guys,
quick question, I'm near the end of a 318 to 440 swap and I know I have to cut the driveshaft some, my question is, how much. I've got an 8 1/4 rear that I'm keeping until it breaks (save some
for now) and a 727 instead of the 904. I've already got the correct slip yolk and I wanted to get the driveshaft to a shop this week if possible. Also, would a machine shop install the new yolk if I bring if for them or do they generally not do that kind of stuff?
Thanks,
Joe

The way I have always shortened a drive shaft is put your yoke in the tailshaft of the transmission. You want measure from the tailshaft housing to the backside of the yoke so you have 1-1 1/2 of the yoke sticking out. with the car on the ground or jackstands under the rear axle you want to measure from the center of the hole where the ujoint goes in the slip yoke to center of the ujoint hole on the rear end and take that measurement to the machine shop and they should fix you up. After I rebuilt my 440 I had heavier tubes and splines put in my drive line. It cost a little extra but I didnt have to worry about it when I got out on I 35 hauling a tractor and eating dads 6.0 liter chevy for lunch good luck
