4.1 liter in 84 regal

[Mikej89]

4.1s were available in '84. iirc they have the Turbo 3.8 bottom end, factory 4 barrel. Turbo it.

Why would they have a turbo bottom end if they're N/A?

It was the "heavy duty" V6. http://gnttype.org/techarea/pictureguides/cranks/crankguide.html

Because the cylinders were siamesed and the cooling wasn't very good.
