Following sequence was done on my '51 GMC 1/2 ton over a period of several
years. Original rear was 4.11 and rear tires were 7.50 x 16:
1. Installed Patricks Saginaw 4-speed conversion
2. Installed Patricks 3.55 ring & pinion and at same time, changed to
205-70R15 rear tires. Net effect was zero or worse.
3. Added Saginaw overdrive to the 4-speed, ditched torque tube, installed
open drive '57 truck rear w 3.90 rear. Net ratio now 2.73 in overdrive.
4. Combined Camaro T5 (2.95 1st gear) with S10 tailhousing to replace the
Saginaw as OD parts are becoming scarce.
5. Next step: Ford 9" rear 3.89 ratio.
