My 69 L78 pace car has a curved neck 4 core. M-21, BU 3:73. Was it optional or just used if the supply of 3 cores were short? Did L89 optioned cars also have the 3 core?

Man, this is some good info. Has anyone documented their 4 core radiator to the cars buildsheet, looking for a ZD or UY code? Keep the info coming!

The gold L78 is a 3.31 rear car. So it would appear to be a factory substitution (presumable due to shortage).
Paul, Not sure what you are looking for, but I have documentation on several cars. All are ZD. The gold car and Chris's car are the only exceptions I've ever heard of.

Looks like the general consensus is the ZD 3 core. Has anyone ever found a buildsheet up in the headliner? My car was a Norwood built 04C model.

![]() My L78 Burgundy convertible showed ZD on the chassis broadcast copy that came off the fuel tank (Van Nuys built), however the car had a curved neck radiator. Drivetrain is M20, 3:55 ratio.

LS6 RAT - Is it the original Harrison Radiator? If so, GM must of had a shortage of ZD radiators and substituted the curved neck 4-core.

My 69 L89 Camaro has a 3 core ZE coded Harrison Radiator with a straight neck. It has been my understanding that all Copos and L34/L35 Cars (with AC) recieved curved neck. Also that all ZD and ZE code radiators are straight necks while all UY and UZ code radiators are curved necks.
Hope this helps......have a great weekend~ Tom |
