Just purchased 1969 435 hp corvette,is it real ?

[70 ls6 convert]

Update..this car turned out to be a complete fraud,engine had 2 bolt cap block,who knows what else he did?..he has other vets for sale,with the threat of going to the authorities,and civil action ,the guy gave us the money back on this car..I will tell you the only reason,and i repeat only reason he got cought was because of the crappy work done on the engine in this car.. After a week of owning this car the engine failed .so when we tore it down we found all the incorrectnes and ground off casting dates..
