Salvage all accessories and parts from motor and sell them on Ebay or to that forum. Throw the rest away and install a SBC or BBC. Stuck with this predicament in 2023, your Grand Father would do the same. You have given a gallant try. Time to get it on the road. Stay away from Buick, Pontiac, Cad, Olds old motors. No parts. Too heavy. Too hybrid. Chevy Chevy Chevy. After about 1962, Every trans fits every motor. More HiPo available.
Stop fighting this. Turn sad to happy.
