I thought Offy was almost a "call us and well cast anything we still have in the catalog" type of company as their production was so low. Think about that, they got all the master cores and are just waiting for someone to place an order....."Uh yeah, can you guys still cast me a dual quad for a 65 273?"--" ...273? Sure!....you want the 5697 high rise or the low rise 5488?"
