Dave...........So....Not only (according to you) is your car the "Only" one of one L-89 Novas made......But....It's the "Only" L-89 produced with 074 Heads.........Is that what you are saying?.......If so.....what is the GM part # for the pistons that were used in the engine rebuild.....In my opinion....If I had the "Holy Grail" car......I would hire someone with the experience to track the previous owners and get a "Documented" history trail of the car to "Validate" the pedigree............After all......since it's so valuable, the slight added expense would be worth it.....
I know I'm going to get in trouble with some here by stirring the pot.......But.....I'm just posting what "Most" are thinking........Again.....If it were my car I would take whatever means possible to "Validate" the History and I would be pushing the paperwork as much as the car.....It's easy to build a real appearing L-89 Nova....I've done it and you've seen it....and it's got a CKP stamped block with Broach marks using GM stamps.......the Block was supplied by a guy that specializes in restoring engines for the Corvette guys...........So.....It didn't just fall out of the sky magically one day......and it's not presented as real......."Validate"....."Validate".......The 074 Heads are a major problem in trying to Sell your story....After all....If the car sells for large Money (as it should if real) and the next owner can prove otherwise.....you will be at Risk...........again....."Validate"....."Validate" .....Puzzles are big and have a lot of pieces.....hard to see the Big Picture with a couple of small speculative pieces
Time to get in the "Bunker".......Just my $.02
