I know the 1969 A12 3X2 Lift-Off-Hood cars had a limited 12-month or 12,000 miles with a special sticker placed in the owner's manual stating the "Same as the 426 Hemi engine" but did 1970/1971 440+6 engine equipped cars also limit the warranty to 12 month/12,000 miles ?? Would dual quads or 3X2 carburetors really make a reliability issue by 4-years and 38,000 miles......maybe down a drag strip at a quarter mile at a time all day and night long. Just can't see the carbs being a warranty period issue. What am I missing? shruggy

RPMs and intended racing use. No warranty on clutches either. I know at our shop (Dodge) if they found you were racing ANY engine they would refuse warranty claims. 5-50 was normal driving. My friends 68 GTS 4 speed 340 cam ecentric broke, they refused service, said he was racing it. He got his lawyer cousin to have a talk, they fixed it.


Be a difficult thing to prove if the car was COMPLETELY stock and someone didn't see you at the track blowing up IMO. I street raced and went to several different drag strips back in '69 and at the beginning the my '69 Road Runner was completely stock. Then I put Hooker headers on it and a "cool can" for the fuel line, and a CDI ignition box (Mark 10) on it and that may have given it away. But I and my friends were smart enough to have removed those things before we would have had it towed to the Plymouth dealer if we hoped to get warranty on it. I'm sure others did the same thing including mechanics that worked at dealerships. Most of the dealers were on the side of their customers when it came to warranty if they could get their customers some help, at least in my neighborhood and not just the Mopar dealers. You had a better chance of getting warranty with a 727 automatic than a 4-speed IMO, seems most of the blown engines that I remember was from that MISSED SHIFT from 2nd to 3rd....... grin grin drive blush
