Whats the value or is it worth it.

Like it or not the car does have more value for being a Formula S (vs a car that is not a Formula S in equal condition)

Roll-bars and subframe connectors can always be removed. (I think all a-bodies should have subframe connectors)

You can find out if it is the original engine by opening the hood and looking for the vin on the block on the bell-housing flange behind the driver side head.


Build it the way you want. As long as you don't do some crazy cutting up of the car, it could be restored later if you change your mind.
