Pinto Engine Swap

another option, and possibly a better one is to use a tempo 2.3 or taurus 2.5L both are push rod engines and use a timing chain rather then a belt. They use the same bell housing pattern as the pinto 4 banger and are a little easier to come by. Also they are about as close to bullet proof as 4 bangers ever got.....Good luck on the swap!
