Hemi valley head bolt tool

[Bird 426]

Just made this, don't know if it's offered somewhere. Didn't like the feel of a crows foot. Now I have to do the 90°/180° figuring thing. It's 2 " center to center.

Mac Tools sells them But they may not sell individual piece. I bought a single 40yrs ago. yours will work fine and probably cheaper.

If it's 2" and your torque wrench is 20" (to the center of the handle) then you would set your torque wrench to 90% of what you want with your gizmo sticking straight out.

Snap on sells the wrench for 34.00

Thanks guys! My torque wrench is 14 1/2 " from head center to mid handle line. Plus the 2 " extension. I have watched 3 different videos on this, with the 90°/ 180°, or straight out. Geometry and Algebra were not ever my strong point, my teacher passed me with a D in algebra if I remember, because I was flunking. That was in the spring of '65, the last math course that I ever took.

Don't feel bad I thought a "d" was a god send for algebra

Hey, I finally get it. Torque wrench centers X Torque that I want. Then that figure divided by center to center plus the length of the extension. 22-44-70

Turned 90 degrees it doesn't change torque.

Yes, think that is how I did it. The 3 sets of numbers up there at the end are values at 25, 50, and 80 . Straight out, not at 90°.
Broke the weld on my homemade tool. Need to find out what the boxed extension above is called so that I can hit the tool guys for a real one.
Thank you!

did the same thing about 40 yrs ago , ended up dropping about 8-10 pounds on the torque reading <depends on the length of your box crowsfoot ...

Although stock is 9/16" if you have ARP head studs that kit might be 12 pt and those are 1/2". I see the California warning on the ones above so be careful if you use that wrench, you might die of cancer tomorrow.

torque X 12 divided by 14 = new torque setting

 

[Bird 426]

Fingers crossed. The resistance will be great. Ordered a set of torque wrench adapters, Wednesday maybe. Always something else to do while waiting.

Good idea on that, I made mine 20 years ago for a friends Hemi but can’t remember if it had factory nuts, might have to make another since I’m using the ARP stuff on my two.
