Sig Sauer the 413 came out in 1959 or 1960 in cars. Around 1963 it was dominating at the drag strip known as the 413 Max Wedge. 1964 I believe the 426 Wedge was introduced and it took over at the drag strips and circle track till the 426 Hemi came out. The 413 stayed in production till the mid 70's or so only available in large trucks. It was also available in Industrial form where it had 2 oil filters and a 8 bolt flywheel flange. Many dump trucks, grain trucks and school busses had 413's in them.
