Horsepower with mileage options

I've always read that Mopar OD transmission require extensive trans tunnel modification plus the problem with finding a non-lock converter. The 200R4 requires minimal (many threads on FABO) mods to the upper cross member and non lock up converter are easily found. I did it to my '69 Barracuda so I know, I have an extensive thread on everything I did to my car (did it all myself).
