I have a set of original, number matching GM tri-power carbs never used, (were used for training purposes only). They are mounted on a block,markedon the bottom Chev.Pontiac,J 2Olds,& Cad. These are the real deal, both ends carbs are not drilled for idle mixtures,they probably should have new kits. These fit the intakes sold by Summit for SBC's $800.00, located in Charlottetown, NO EMAILS, Phone calls only 902-566-5778,Thanks,Brian
