honestly the only correct way would be to have joel document it for you.that is you pay him $1500 and he'll check his build sheet info against the cars info i.e vin# .you might have stumbled on a rare find or it could be just a 1968 BBC chevelle with motion mail order parts added to it.things to look for would be i've heard of a stamp on the block that motion would have put there during the engine building process.other items which are probably gone by now would be a 4.56 geared 12 bolt posi,motion valve covers,green flex a lite fan,motion c-d ign system,fly eye air cleaner.hope this helps
