I just purchased a 64 F-100 stepside with 223 and 3 speed. The old truck is in pretty solid shape with a few areas that need some attention but the engine runs great. I have several questions to ask.

1. I have only 3 or 4 leaf springs on the rear, is that normal?

2. My axle code is 12 which equates to a 3.89 diff. However when I rotate the tires and count the drive shaft rotations I count 2.5 to 2.75. Is that right or would you think the 9 inch rear has been changed?

3. When I let out the clutch I have to rev up the engine because there doesn't seem to be a lot of low in torque. The truck has plenty of range between shifts and 2nd gear I can wind out to around 40mph before shifting to 3rd. Is this typical of this engine and tranny combination? Or does it relate to #2?

thanks, Gary

 

First & foremost welcome aboard; I too recently purchase a 64 model SWB Styleside; I can't answer your reason on your ratio by the # turns you did, but will agree to your third comment, my 223 needs so juice to push it along. But hey I'm alittle older than my trucks and need a little juice ( Coffee) to get me going as well. Looking forward to hearing more about your Slick; mine are in my gallery..
Again welcome aboard.

So your 1st gear hasn't much torque either? Sounds like these trucks both need new differentials with lower gearing.

thanks for the reply, I will try to post a picture of my truck here. If will the the flat black rat rod looking 64.

Forgot to ask how many leafs are on the rear of your truck?

Your truck looks to be in good shape. I see you are from Tennesee, my brother and mother live there also. I grew up in Huntsville, Al, I now live in Il and soon to move to Indiana. I would appreciate any info you could share and I will do the same.

thanks, Gary
