71 EV2 Duster Twister Fold Back Sun Roof

Have had a little time to mess with the car here lately. Few new parts but it is still out of time. Should be here at home within the week so I can mess with it more. Anyone know where the vin is on the engine? I would like to confirm that it is numbers matching. If it is not, there is a 340 with a 727 and headers on craigslist last time I checked that needs a new home. If its numbers matching and everything is good with the engine, it's staying.
