The Plymouth Belvedere was a model of car produced by Plymouth from 1954 to 1970. In 1966, the Belvedere was available in several trim levels, including a 440 version, which was equipped with a 440-cubic-inch V8 engine that produced 375 horsepower.

The 440 version of the Belvedere was also available in a performance-oriented “440+6” variant, which featured a trio of two-barrel carburetors and was rated at 390 horsepower. Both engines were paired with a three-speed TorqueFlite automatic transmission, or four-speed manual transmission. The 1966 Plymouth Belvedere 440 was considered as one of the great muscle car of the era.

Whiplash cams are designed for the very low compression Mopar O.E.M.  engines such as all the 318’s, 360, 400 and all 383 & 440’s built after 1971. The factory built these engines with a combination of low compression and cams that produced very low cylinder pressure and low power

Normally, to increase the cylinder pressure in these engines you would have to disassemble the engine, buy new pistons & rings (at a minimum), rebore & hone, rebalance and reassemble. And then you would still need cam & lifters. The cost of this build-up could easily be $2,000.00 or more and take 2-3 weeks.

What’s not to like about them? An engine lineup that ranged from the reliable and economical 225 Slant Six, through the 318 Poly (making its last appearance that year), to the low-deck 361 and 383-inch B engines, to the 426 Street Hemi.

In the video below we have a beautiful, nice looking car, with a color which fits perfect and it really sounds great. Listen to it and you won’t be disappointed.
