Olds told GM to go fuck themselves basically by sending the cars out to get converted. the cars left olds as 442’s and sent to Demmer Engineering NOT HURST to do the swaps. the hurst olds isnt the same as yenko, royal, sox and martin, grand spalding… they were sold at any olds dealer not just one specific dealer.
thats not a list of pontiac firsts either, its a historical timeline of stuff they did, not things they did before anyone else.
GNX, Hurst Olds, Turbo Trans AM, Aero coupe monte SS, 69 440 6BBL Road runner/superbee were all cars sold through the factory but converted offsite.
