Hi! I just pulled an engine out of a 62 300 non letter...it's a 1961 413 block...I think the heads on it are not original and I'm curious has to what there original application was... casting ends with 516. Anybody know what year and engine these were design for?? 440 maybe?? Thanks! Jean-Yves in New Brunswick.
