I AM THINKING OF PUTTING A 400 SMALL BLOCK OR AN EDELBROCK 350 THE 350 CRATE PUTS OUT 410HP AND 408LBS PER FTOOF TORGUE BUT I KNOW JUST ABOUT NOTHING ABOUT THE SMALL BLOCK. AND WICH ONE SHOULD I GO WITH?

 

since your not familar with engine building i would go with one of the various crate engines.

 

Torque is pounds times foot, not pounds per foot.

The 400 is certainly more complicated. If you aren't familiar enough to know the differences, then TempesT68 has it right. Even with a crate engine, you'll run into details that will need some noodles to resolve.

No intent to flame, just reality.

 

Actually the term "pounds per foot" is correct.

That action of lifting a 1 lb. object 1 ft. off the ground is 1 lb/ft., or sometimes called foot/pounds. Either way is excepted.

Anyway, if you lift a 50 pound object 1 ft. off the ground, then that is equal to 50 lbs/ft. That's 50 lbs. per foot of distance, or pounds per foot or also written, 50 lbs/ft.

It's a fixed distance, rather than a fixed weight. Although 50 lb/ft is the correct way to express it, we still say an engine has 350 ft/lbs. of torque.

So when you are turning a head bolt and tightening it to 65 ft-lbs., you are exerting the same amount of work that it would take to lift 65 lbs. one foot off the ground, or 65 lbs/ft.
