A friend is trying to rebuild a kit, (moss malvern), but wants to replace the tired spitfire engine and box with something that can have an AUTO (big feet, small pedal box). Now power isn't a major issue due to the nature of the car, but engine bay space is....I heard that the pinto is a lot taller, and heavier than the CVH, but which of the CVH's will fit onto a type 9 auto box? is there a difference between the 1600 and 1800cc input shafts?
would a sierra 1800cc to sierra auto box be the easiest option?

If anyone can link to info on these conversions etc, then much apprieciated.

Many thanks.

Matt.

Easiest to put in a Triumph Dolomite 1500 auto engine and box -- the auto box is the good old BW35 very reliable.
Usually a few triumph 1500 automatics on ebay.

Note the Ford C4 and C5 autoboxes are a tad unreliable at high mileages
