The calculation of the net horsepower available at the propeller under these normal conditions is particularly simple.

The 350 engine was rated at 145 net horsepower with a two-barrel carburetor; 175 horses with a four-pot carb.

With 134 net horsepower from the hybrid system, the Prius V isn't a rally car, but acceleration will be adequate for most of its economy-minded owners.

Optional at extra cost was the W-30 option with the L77 455, a blueprinted engine rated at 300 net horsepower.

While these were the biggest, most powerful engines available from Ford at the time, they were still underpowered at 202 net horsepower.

By 1976, the last year for the 455 engine in the Toronado, the rating dropped to 215 net horsepower.

The 455 V8 was carried over and now rated at 250 net horsepower compared to 315 gross horsepower in 1971.

The 1979 VAM 282 six cylinder engine was rated at 132 net horsepower at 3,900 revolutions per minute.

It came in a number of trims and colors while the 350 engine was rated at 145 net horsepower.

Under the hood, the standard engine was downgraded to a four-barrel 350 V8 rated at 175 net horsepower.
