I spent about 7 years researching this already... with that said, I'd say the heads were installed somewhere along the way, the piston/head combo ain't friendly with stock GM head gaskets... I can't explain the P-Plate though Lucy..

[/ QUOTE ]Instead of looking at the heads which could have been changed early on perhaps in error under warranty the POP and the block stamp should be examined carefully.

From the Hemmings write-up:"On the mechanical side, Brian Henderson of Super Car Workshop, who had recommended Legendary when his own slate was full, examined the block's decks to see if the factory broach marks were intact; this was a means of determining if the code and VIN stampings were legit or recreations. Reportedly, despite initial skepticism, Henderson came away convinced that the engine was unmolested; because the CKT code is unique to an L89 Nova, this looks to be the only one known to exist.

After Henderson looked at the engine, Legendary had Active Engines in Mississauga, Ontario, go through the block again."

Looks like both "Active" and "Henderson" need to take a SECOND look !

[/ QUOTE ]I don't believe the CKT code is unique to the L89 Nova,just unique to 70 L89 but what is unique to a 70 L89 nova is the CKT block with with the Willow Run W in the VIN code.

Did I miss the picture of the unpainted engine stamp? Isn't that 50% of the documentation on this car. m

From a Post over at Steves Nova Site......

Plus, I've seen original broached 854 blocks with no stampings, and they make paperwork. If the owner (s) had claimed the 842s had been replaced with 074s I might say OK. They really need to fine the original owner if possible before I'd suggest that it's real, and anybody lay out heavy money for it.

Boy, Tibor's profile is right....he really is a numbers guy

11.0 to 1 with 842's and 9.5 with the 074's....and a possibility of the Domes on the Stock L-78 Pistons hitting the Combustion Chamber in the Exhaust valve area....the Closed Chamber had a straight sidewall next to the exhaust valve which shrouded it......the open has a much larger chamber, but to unshroud the valve, they open up that area, but tapered it and that's where possible contact would occur........
