I started racing in NHRA stock class at the 1974, maybe 1973 or 1975, NHRA Winternationals the year Mopar made all their factory sponsored Pro Stock racers switch back to racing in the NHRA S/S classes, Dick Landy built a 1971 Challenger 4 speed car with a 440 6 pack motor in it with a T/A fiberglass hood on it for that year, tech threw him out and one of the Mopar Drag race team members wrote, type up, a letter stating that Dodge had ran out of Shaker when Landy car was made and they installed one of the "left over 1970 T/A fiberglass hoods" (AAR Cuda and T/A Challenger didn't sell worth a hoot back in 1970) on some of early 1971 Challngers with the hemi and 440 6 pack motors in them in the beginning of the 1971 production years due to not having any complete shaker hood kits for several weeks in the late fall of 1970 , which was a made up factory effort to get him into that race, which NHRA after seeing that letter let him back in to race at that race.
I think he lost in the 1st or 2nd round of S/S class racing on Friday due to red lighting
Cheaters never win
I was helping a customer, Steve and Linda Myers, race a 1970 Challenger R/T in A/SA that they had bought from a junk yard in SO CA with no motor or tranny in it, I had sold them a hemi moor , trans and K member from a total 1968 hemi Road Runner and installed in their 1969 Plymouth GTX Pink Panther which got wreck on the trailer going to a race earlier that year
They ended up buying the complete Shaker hood kit from DLI in April or maybe late march of 1973 or 1974 (CRS now,:confused): to get the fresh air into the carbs.
Lots of politics back then by a lot of racers and NHRA sponsors like the car makers.
I'm pretty sure that letter caused all the controversary about the fiberglass T/A hoods being used on other non T/A cars from the "factory"
