From those of you that swapped the Fordomatic to a C4in Thunbderbirds, what driveshaft changes are necessary?

Always throws me off when I see your signature.



Anyway under tech articles there is one on C4 into a Thunderbird. He had to lengthen the driveshaft three inches. When I do my C4 conversion (already have the trans), I planned on comparing overall trans length from block to end of tail housing, taking into consideration any shaft extending past the housing.



Currently I'm waiting to do the install until I build another engine, and the current one is running pretty good and not using any oil.

The only change is getting a longer shaft. I had a drive shaft shop make up mine, using the rear part of mine with a new front for the C4 slip joint.
