Bob,
Good guess on the 335 series. According to the Ford Performance Chronology of Ford Engines, the 335 series was the 351C in 1971,72, & 73. It then became the 400 in 74, and was the 351M and 400 in 75 up. The 90 degree V family was the 221,260,289,302,Boss 302, and 351 Windsor engines.
Quote from book. " The oldest of the modern Ford engines and the most varied is the big block, or the FE family, which began production back in 1958 with two sizes, 332 and 352 cubic inches."
I had a 58 Ford with the 332 PI and it was a great engine.
I think the original Edsel Engine should have been designated EF. EF = Entire Flop.
