Wow, I had an easier time over the weekend introducing my new honey to Mom! .
Anyway, very cool car Ralph...it's this one right?

The L89 Nova debate has just never been clarified YET, so please stick around w/ the car and don't be too upset at the hungry pack of dogs reaction to the bone you've tossed? .
I see you've indicated previously it's a matching Vin JH suffix motor...so all would indicate shipped as an L78...and obviously the POP won't help. .
Did you ever get w/ the original owner or dealer? . If yes to either/both and no documents to support but there's agreement to the dealer installed thing...get a sworn statement(s) while possible! .
If nothing else ever shows up, this could be the closest things ever get to documenting these? .
For all who care...why when reviewing suffix possibilities for a factory shipped L89 Nova, each L89 suffix notes only Camaro yet when looking at L78 suffixes it notes a shared suffix w/ Camaro, Chevy 2/Novas? .
Maybe this happened when the info was gleaned but it looks this way in what I've read? .
If indeed factory shipped L89 Camaros were available and Nova's had to be finished at the dealer level, you'd think there'd have been a bulletin on this subject? .
And Ralph...nice list is right
