When you get the pully fully seated how much space is between the crank and the pully or is it flush?

[@3rdGenC10s]

I’m not sure, didn’t really look.

[@Kloco78]

That’s my question

[@tomharmon9663]

Torque angles are such a pain in the ass.

[@3rdGenC10s]

Yes they are.!

[@Josh-jy9rj]

Yessir!

[@3rdGenC10s]

Dropped the motor and trans in the 74 today!

[@MOE13576]

[@3rdGenC10s]

Patriot Blue

[@MOE13576]

That's a nice looking blue

[@3rdGenC10s]

@@MOE13576 I appreciate it, closest I could get to the factory color of the truck.

​@@3rdGenC10syou're welcome. It came out nice. First time seeing someone painting it a different color other than orange.

[@MOE13576]

@@3rdGenC10s and I was going to ask. Since I don't have a degree torque wrench finder. Can I just torque the final bolt to 257 Ft pounds (37+220 ft pnds) ?
