[T3] Torque wrench?

[William Jahn]

 I only have two 3/8" drive 5-75 click type , on is an older sears with
numbers in a window and onee I got at auto zone which has the scale
micrometer. One 3/8" bean type 0-800 in lb and 0 90 NM . and a 1/2" beam
type for the lug nuts , also auto zone. And a 1/4" 20-200 in lb.

 My main concern was torquing the runners to the heads. I did use the old
sears set at 14 ft lbs and it clicked with very little effort, meaning it
felt right. I wanted to try and compare each just to see what they actually
read. .
