What about the trans bolt up? Same pattern on thr v8 & /6?
I have a 73 i just picked up n wanna do the same. Although i read on wikipedia
That certain 1975 set ups could get you like 35mpg hwy.
Thats sounds awful tempting for a cool old cruiser too.

no the slant 6 and v8 transmissions do not interchange unless you buy the very expensive scarce as hens teeth adapter

and it was the feather dusters that got good fuel mileage but that was because of all the super light aluminum parts used and gearing and much more
