horsepower and torque ratings

My67_fastback · December 28th, 2006, 09:32 PM

for a 351w engine? cant seem to find anything on the stock power of this engine, other than one mention of something like 250hp for 2v and 290 for the 4v. are these correct? and what is the torque rating?

I found horsepower could be anywhere from 153-290 horses. Not sure about the torque.

Between 1968 and 1972, the 351w put out anywhere between 250 and 330 BHP. Im not sure on tq, but I am still looking.

I didn't find the 330hp

Those years range from 1969 to 1973. With the 1971 S-code BOSS 351 rated at 330 HP(Encyclopedia of American Cars over 65 years of automotive history).

A 351w is not a boss. So, back to a 290 at the flywheel being a high.

There is a big difference between a Boss 351 and a 351W........

cleveland heads for the boss. but anyways, ya i cant find it anywhere. but ive found the 289 and 302 to have around a hundred more ft-lbs of torque than horsepower, so id assume a 2v 351w may bring 250hp and 350 ft-lbs. but im wanting a confirmation from somewhere. hmm... guess noone knows TIME TO DYNO!
