In all honesty, this one would have definitely been in our Top 10. Unfortunately, this legendary engine came up just short in the voting and finished just outside the list. The Ford Flathead 221 is essentially the engine that started the hot rod movementHot Rod magazine even did a comprehensive guide to the Flathead.

The Ford 429 engine was born in 1968 but became legend in 1969. That’s when Ford introduced the Boss 429 Mustang, which was powered by a Boss 429 engine rated at 375 horsepower. By most estimates the rating was quite lowas were many ratings during the muscle car warsand the engine actually churned out over 500 horsepower!

The Chevrolet 327 came in multiple horsepower versions and was offered in a wide range of automobiles from 1962-69. Because of the mass availability of parts for this small block engine, it remains a favorite among hot roddersas the voting proved.

The Pontiac V8, most specifically the 421 Tri-Power, was popular among voters. The engine was initially introduced as a racing engine for the 1961 and 1962 model years, but was released for the general population in 1963. The 421 Tri-Power was basically the king of Pontiac performance in the 1960s, delivering 376 horsepower.

The 351 Windsor made the Top 10, but the 302 was one of the longest running engines of all time. First offered in 1968, the 302 is best known by performance enthusiasts for its use in the Mustang. It was also commonly known as the Ford 5.0L, although it actually only 4.942 liters. (The 4.9L moniker was already taken by the 300 I6).

Chrysler 440

Although not as powerful at the 426 HEMI, the Chrysler 440 could be purchased for about half the price. The bang-for-buck power made this engine a favorite among voters for the Top 10 list. The 440 was the last of the Chrysler mills above the 400 cubic inch mark, and with the addition of the “six-pack” carburetor setup from 1969-71, it really packed a punch.

In 1987, the Buick Grand National was called America’s quickest car. This was due to its use of the Buick 3.8L turbo, which was first introduced at the 1976 Indianapolis 500, where it was used in the pace car. By 1978, Buick offered the 3.8L turbo as a production engine and its popularity rose throughout the 1980s.
