Harmonic balancer tightening (crank bolt) engine in car with 4spd manual transmission

I should have mentioned coming up on tdc for that cyl, that's what I did(half-assed followed instructions again lol)
If it was on something like a Chevy 350, I wouldn't sweat it. But a Chrysler with a 3/4" bolt. That takes a lotta torque. lol
