TDC Help on SBC Crate Install

[Starwood]

So...nearing the red zone on my GM performance 350/290 crate swap. It's my first (and hopefully last), but this was something I really wanted to do myself. It's been a "unique" journey to say the least.

Along the way, the crankshaft was moved a bit during the harmonic balancer install and it's no longer TDC. Long story...

Anyway, I need to get her set at TDC and I've researched that I should be able to rotate the engine manually by turning the crankshaft bolt clockwise until I line it up with that first Driver's side Rocker Arm #1.

Belts are off, oil pump primed, and plugs removed - but the balancer and crank pulley remain on. (Note: Distributor is seated (cap off), and rotor is currently pointing to Rocker Arm #2).

With these items addressed, it should be able to rotate - not freely or easily - but rotate with reasonable force, correct?

Well, it's really stubborn - and I haven't yet given it my all with an extension wrench - but my biggest fear is busting or breaking that bolt or doing other damage.

Reaching out to confirm if I am on the right track to go for it - or if I may be missing something and headed for a very disappointing Wednesday.

Please reply with any thoughts or tips if you have a sec.

Thanks Fellas.
