Ladies and gents where i live right now its a rainy day so i thought how about a rainy day story/history lesson! on my favorite engine the SLANT SIX!

The slant six engine was introduced in 1960 in two versions - 101 hp, 170 cu. in. and a 145 hp,
225 cu. in. From this modest beginning, the slant six built its reputation for performance and
reliability. The 148 hp, 170 cu. in. Hyper Pak introduced in the 1960 Valiant was the next step
and the one that was to prove the new engine worthy of any performance challenge.

In 1960 with the introduction of the new compact cars by all the American automobile
manufacturers, NASCAR sanctioned a special race exclusively for the little 6 cylinder powered
compact cars. The race was held at Daytona and had seven slant six Valiants entered. When the
race ended, not only had all seven HyperPaks finished proving their reliability and durability,

they won the first seven places! This type of performance speaks for itself.

The Hyper-Pak option was carried over into 1961 and also made available on the 225; but, 1962
was the beginning of the "big-inch" factory hot rod and the Hemi was coming! The little slant six
got lost in the eight-barrel carburetors. The slant six now had to settle for the more mundane job
of economical and dependable transportation.

The performance history of the slant six had the usual highlights: four-barrel intake system, high
compression pistons, long duration mechanical camshafts, aluminum blocks and one of the first
performance four-speed manual transmissions with an in-line six in 1965. But, that was in the
60's and the emphasis in the 70's was fuel economy.

Again, the slant six was equal to the task. In1975 the Feather Duster and Dart Light were introduced to demonstrate the economy of the slantsix. This package had a four-speed overdrive and many lightweight body pieces. The slant six responded with an EPA highway number of 36 mpg. This is the best fuel economy turned in byan American 6 cylinder compact.

At the end of the '69 production year the 170 slant six was dropped and in 1970 a new 198 cu. in.
version was introduced to replace it. At the end of 1974 his version too was dropped and only the
225 survived until 1983 in cars and 1987 in trucks and finally was discontinued in 1991 after its stint as an agricultural engine and boat motor.

The three engines share a common bore of 3.4". The 170 engine has a 3.125" stroke; the 198
engine has a 3.64" stroke; and the 225 has the longest stroke at 4.12". Major internal differences
between the engines include crankshafts, rods, and camshafts although the camshafts can be
