I think it is also important when using torgue wrenches that the cheapies ain't all that exact... If you have a friendly Snap-On toolguy he'll take yer wrench and check it for accuracy... This is more important on newer engines with aluminum and alloyed components as they are less forgiving than the old cast iron engines where you could get by nicely without a torque wrench as long as you had developed "the feel"...

BTW, John, I used to build air cooled VW engines and the torque requirement for the flywheel gland nut was 275 ft pounds... Purdy tricky 'cause you had to use a 4 foot long pipe extension to crank 275... And ya' also had to have someone with a foot on the No's 3 & 4 Cyl. head to keep that side of the engine from lifting up from the torgue... No fun....
