torque: 292 v. 350
Anyone know which has more torque: 292 v. 350? How much and at what RPM? I need a temporary motor for my
72 3/4 4x4, and have a chance to install a cheap 292 but don't want to give up too much torque. thanks, Steve

Torque yes, HP no...
Give up Torque? The 292 is king of torque over the 350...hp no...torque yes. I'll try to look up the actual figures but the 292 was within 30 lb. ft. of torque of the 454 in'77! This torque however comes in the low rpm range. If you want quick takeoffs, this probably isn't the engine you want but if you want raw torgue and can live with the slow takeoffs this is THE engine! Remember, the top choices for dump trucks years ago were the 427 and the 292. 'Nuff Said? Good Luck!

As a general rule, on a mild street motor the torque ft lbs will be somewhere close to the cubic inches ussally a little less. Here is an page that has a 292 dyno test.

Peak torque is directly proportional to cubic inches. Without the benefit of specs, I would say a stock 292 makes maybe 270-290, whereas a stock 350 makes prox 330-350. Now, at low rpm, like around 2000, they may be very close, because the 292 may make peak torque at 2500 rpm, the 350 at 3500 rpm. I may run this on Desktop Dyno just for grins. I also have a 1969 Motors repair manual somewhere that lists the factory specs.

Gentlemen,
Thanks for the replies. It sounds like the 292 is well suited for slow 4 wheeling. I wonder how the gas mileage will compare? Thanks again.

Probably not that much better gas mileage with the 292. And you could probably build a 350 for less than a 292. Just about any part you can name is cheaper for the 350. But the big six would be kinda cool because it's different!
