I have a 318 crank if the others don't work out.
Thanks, Mark

I would let you have mine for free but I think you are in the same boat I was a few months ago. I called the shop that did mine to see if he still had one left, I will post when I hear. Good luck.

Is a 273 crank the same?

 

[swinger340]

273 w threaded flange will work. Of course all 3 273,318,340 are balanced for different bob weights.

 

[LEVOHS]

Thanks everyone, A crank found me.

The forged 273 cranks can be used but... the center register will need cut for torque coverter nose or pilot shaft. Then a bit of material removed to balance the rotating assembly with the lighter 340 rods.
I think these are the only differences. I've been wrong before.
I know a guy who builds any and every LA racing engine balanced like a 360.
