I have a picture of the fuel line (one) on the pass side inside frame of my 1969 SS. Some cars I have seen pics of have two lines. Dan said his is a 325hp and has also owned a 350hp with both having two lines. What do you think? Is this a sign that it is a 375hp car?

If you know that for sure the car is an SS, and that it is the original line, then yes it is a sign that it was probably a 375 Horse car.

It looks like the original line and clamps!:yes:

I will post pics of the tank later today.

Monaco Orange.... She's the real deal. Like Rick said. One fuel line = L78....

Here is the fuel tank

That's a great find. Congrats.

I had a similar discovery last year on my '69...

Yep, if that's original and it sure appears that way, it's very likely a 375 hp (or a slight chance of a COPO 427)

Great question, as I understand it the COPO cars were based on the 375hp cars, not malibus. Only stands to reason since they would share fuel lines, intakes and a few other items. This would be a question to be answered by the copo experts.There were 6 colors offered in the yenko's and orange or yellow were not offered. Maybe other dealer copo's did offer these colors but not sure.

I think most, if not all, 69 Chevelle COPOs were based on the Malibu series, I know the one build sheet I have a Chevelle COPO is a Malibu (13637) sport coupe. I also have several other build sheets of 1969 SS396 Chevelles w/the L78 option.

I have yet to see a Monaco Orange or Daytona Yellow 1969 Chevelle with the appropriate color codes on the trim tag that were not SS396 optioned. Other 1969 (and later) Chevelles done in these colors either have the DuPont paint mixing formula listed, dash characters, or the paint code left blank; of the last two tag markings, only paperwork would show the original colors.

dales right all COPO's that had code 72 or 76 had dash characters instead of #'s.i have a special order ralley green 69 with those markings. greg

I'm a newby so what else was on the COPO? This car has rear shocks with coil over springs that look VERY old. Have not removed them yet and so far I have not seen anyone with them on it in pics on this site. Does anyone have a 69 copo with a photo bucket?

Dale, now I'm confused, everything I've ever read on the subject states that the copo cars were slated for the 396/375hp (never do they say SS but they'd have to be) and when the cars came down the line the 425hp 427 was installed instead and never receive the SS badging. What I meant to say is the copo cars were not just based on a malibu version of the 13637 but a 13637 hardtop slated for the Z25 option. I wasn't specific.

There were 8 colors offered for the Yenko 427 Chevelle and monaco orange and daytona yellow were offered. These cars have the dash on trim tag and no paint code.

A 1969 13637 SS396 Chevelle is a Malibu with the Z25 SS396 package added. There were also 300 Deluxe SS396 cars as well. There was no separate 138 SS396 model as in previous years. The COPOs were also 13637 Malibu models with the Malibu interior, which was the same as the SS396 interior. The exterior was all SS less the SS396 emblems. That is about as simply as I can explain it. For some reason, the documentation shows the L78 engine as well as the COPO 9566AA or BA package. The COPO cars could have the Monaco Orange or Daytona Yellow. The KQ 4.10 rearend seems to have been the standard rear for the COPO cars. Our L78 car has the KK 4.10 rearend. Looks that your car is at least an L78 car and it would be really nice if it turned out to be a COPO. There are quite a few unaccounted for. Here are some shots of our car over the years. It started out silver and I added some emblems, header, Hurst shifter, and wider tires over the years. The second set of shots is of our 300 Deluxe L78 Chevelle. Both were silver when new. http://rides.webshots.com/album/561239037IQexug http://rides.webshots.com/album/560001407BJbiIt

This is the rear end stamp:

Looks like a 1970 3.31 Positraction. The 0521 (May 21) obviously isn't compatible with the 01A (January 1) body date.

Not to put a damper on the COPO idea but weren't most COPOs built in the Baltimore plant with only one known to be from the Freemont plant? This one being an Atlanta build wouldn't it be less likely a COPO and more likely an L78? Understand there is still a chance that there could be some undiscovered COPOs at this point. Either way it is a good one to have.

I have taken both motors to the machine shop today to get them checked out. Will know something Friday or Monday. I may build the 67 396 back to specs so that if and when I find a 375hp KF motor I might find someone needing my 67 Impala 396 long block with the 100cc heads. I know it will never be a #s car but it would be neat to try to have it back stock.

I have a 69ss--350hp 396 car and it has a 1/4" return line along with the 3/8 fuel line.
Would a 68ss that has a single 3/8 fuel line lean towards it being a L78 car?

In general, the fuel line was dictated by the carb. The Q-jet needed 2 fuel lines and the Holley just used one.

There are some exceptions such as in when the air pollution controls were used.

Some of the 6 cyl and 2BB cars used one 5/16 fuel line

Maybe on big blocks in '69 but not on small blocks. Many 350's with Qjets had a single 3/8" line.
