The net horsepower of a Ford 351 Cleveland engine is between 175 and 300 horsepower. The actual output varies based on the specific components used in the engine.
266 is the Net Horsepower Rating of the 'M' or 'Q' code 1972 351 Cleveland engine. The 'R' code engine was rated at 275 net HP in 1972.
in 1970-1973 ford introduced the 4 barral carb 351 Cleveland with a horsepower rating of 300
266 horsepower@ 5500 There is too much incorrect info out there re: the 351C engine. 266HP net is correct for '72 (M or Q code). The '73 351C 4V (Q) was rated 248HP net due to lower compression (dished pistons) and smaller valves. All my information is taken from original Ford literature.
250 horsepower - 351 Windsor - 2 barrel carburetor - in 1970 ( not SAE net )
engine horsepower is the total power produced by an engine.whereas net horsepower is the remaining power after power loss from many reasons..in aviation, they call brake horsepower.
154 / 159 / 161 /163 / 164 /177 ( 2 barrel ) The '73 351C 4V (Q) was rated 248HP net. All my information is taken from original Ford literature.
Net Horsepower instead of gross. net measures with all accesories on the engine. or you could rate it at a lower rpm.
== 215 net horsepower, 285 ft.-lbs. of torque
Net 165HP@4300RPM
20.8 Net HP 24.47 Gross HP
Around 280 net hp
I believe it is 300 SAE NET horsepower at 5000 RPM and 365 lb ft torque at 3750 RPM for the 5.4 3V
