I put a 55-59 truck center section in my 50 truck housing. We cut off the pivoting perches and welded on solid perches. My friend has done the same thing with a 39 truck housing installed in his 30 Chevy coupe to convert to open drive. 3.90 gears and T5's in both.
A 3.90 gear set with a T-5 with .72 overdrive with stock height 28" tires is about as dialed in as it could get for a 216, 235, 261 Stovebolt.
There is an old adage, "There is no such thing as free lunch". Not true at all with the advent of putting a T-5 behind a Stovebolt.
I sure would like to know who the first person was who did it.
