To add to that since the masks were reused they would suffer some deterioration and more overspray would get on the aluminum. On every original aluminum engine I have ever seen over the last 40 or so years there was some amount of Chevy orange but it varied from engine to engine. You can duplicate it pretty easily with a little thought, but installing the intake after the paint job would not appear factory correct. Hope this helps......Bill S

Thanks for the info. Understand how that overspray could happen. That picture of this intake with the overspray is what was duplicated to look factory correct?

Heater hoses should be ribbed with no stamp. UPC bar codes did not exist in 69, alternator must have come from pep boys.

The corvette boys like to see some overspray from the mask, but they went overboard. Temp sensor in head looks like the wrong fitting.

Not a fan of the color and that will bring the price down. What’s up with the positive lead going over the battery to get to the junction block on the core support

A few 9511 Camaros are known also I think Chevelle or two but the '69 Novas more elusive and one an sYc Member reported having back in one of the old threads seemed the closest X-car possibility up to then.
I'm a work so can't dig for the old threads but was it you Tom w/ the example you let go of that seemed possible also was it a factory 4:56/4:88 car or?
Again, I don't expect the subject car is anything special but would still love to see a real '69 Copo 9511 X-Body if anyone knows of any.

Can't help with the car but I know the rears exist. I have a BX code 12 bolt with a 69 date, complete with GM posi and GM 4.88's in it. Pulled it out of a friends wrecked 69Z but I don't know if it was actually original to his car or not.

If it was originally a COPO 9511 car - it isn't anymore:

The L78 Engine is Mated to a Counter Case Muncie Four Speed Trans that runs back to the 12 Bolt Posi rear with 3.55 Gears.

----No, that's somebody's incorrect take on Chevy orange intake overspray. It would never have been fogged over the first two inches of the intake runners. There would have randomly spotty orange missteps along the edges of the intake up against the heads. We are going to have to ask for some pics to explain what I'm getting. Hopefully someone can rummage up a few pics that show what I'm trying to explain. Help!......Bill S

I thought the masks were a molded plastic. But Bill's explanation is spot-on and Lee's pics show it.

There was a COPO Nova Police car package built in 1974 as a small number of prototypes. They were sent to some police departments for testing. In 1975 Chevy made the COPO 9C1 Nova as a police package.

Those Nova police cars were pretty impressive. F41 suspension, heavy duty brakes, etc. A guy i worked with years ago had a 1977 Nova police car he bought at an auction. I rode in that car and it had some get up and go and handled well with that F41 suspension package. Again these cars were rated right up there with the best police vehicles.

Wilma is correct, had a 69 L78 Nova with a BW coded rear (4:56) all the guts of it were gone, but housing cast date and assembly date jived with the car build date. I had a Fischer build sheet and have pics of the rear somewhere. Will hit the archives and see what I can find
