Inch Torque Wrench

[brentmcq]

I am getting ready to do a cam swap on my 2v SOHC. It calls for tightening the cam caps to 70-120 inch lbs (not foot lbs). I have an expensive torque wrench but it's in foot lbs. Where can I get an inch lbs wrench and how much do they run? Would 120 inch lbs = 12 foot lbs? My wrench also measures in meters (I guess for Europeans)..

Using a ft-lb torque wrench would be fine. However, you may wanna recheck your math: 120 in/lb = 10 ft/lb. Also, go in the middle, rather then top end: like 100 in/lbs = 8.5 ft/lbs. Good luck.

thanks. Yeah that was fuzzy math, hey I was tired. So if I went in the middle of 70-120 inch lbs I'd be looking at tightening to 5.83 - 10 foot lbs. That's hardly any torque is that tight enough?

Yup, sure is. It's going into aluminum, where the metal is a lot softer.
