Default what torque wrench for building my engine?

I am going to tear my 99 Z28 LS1 engine down to a bare block and rebuild it with forged rods and pistons, and I need a torque wrench. What torque wrenches will get the job done, and which one offers the most bang for the buck? I don't want to pay the "Snap-On tax" and was considering something from Sears because I'm only a weekend mechanic... what do you guys think?

Thanks, -Dave

Ah F-it, my dad bought a Snap-On digital torque wrench set... 3/8 and 1/2 drive rated at 100ft/lbs and 275ft/lbs... set him back $600 and it was on sale!

Seems like he doesn't mind paying the Snap-On tax... sometimes their stuff is nice to have, but I don't know if we really needed that much tool...

The digital wrenches are ok I dont like the feel they give when you reach your torque spec...plus they are spendy....I have a snap on 1/2 drive micrometer style wrench and it works well plus it was only 250....Think about the time and money your putting into this project it only make sense to spend good money on tools...

I definitely agree. With something that needs to be dead on why take the risk to save 100 bucks? I bought my 3/8 snap-on for i think 230. plus there is no interest off the trucks. just drop the man 20 bucks a week if you cant pay in full.

You are going to need one for inch pounds also.

Foot pounds and newton meters are usually on the same torque wrench, not inch pounds. I bought an inch pound torque wrench from S-K a few years ago for like $70, high quality. Do not buy the Harbor Freight junk.If you use a foot pound torque wrench and multiply by 12 to get inch pounds you are taking the risk of an inaccurate reading. This is because torque wrenches tend to become inaccurate at the very bottom and the very top of their ranges. So tightening the intake manifold bolts for instance you would be at the bottom of the scale. I think those bolts only get like 96 in lbs, and they are east to strip.

Yeah, it has inch pounds on it too (converts to any of the three with the press of a button). I've got the 1/2" digital one. Definitely worth the money. Saves time and keeps you from making stupid mistakes when you have to convert from inch pound to foot pound and vise-versa. Your dad made a great choice.

I like and use the Snap on digital Techwrenches. If you check the specs they are the most accurate and it is what I have been using for a few years

Is there a Minimun Setting for the Inch Pound TQ Spec. on this
"All-In-One" TQ Wrench by Snap On?

Just Curious because I have the
Craftsman 1/2" Drive (0-250 ft.lb)
PROTO 3/8" Drive (0-150 ft.lb)
(2) PROTO 1/4" Drive (0-200 in.lb)

Thinking about purchasing the "Snap On" TQ Wrench myself.
I'll still keep my others as spares though.

The Snap On one would come in handy for doing Gear Swaps.
Especially for Adjusting the Pinion Depth

I love my Husky 1/2" torque wrench from Home Depot. Lifetime warranty and it was $50 or $60.
