So im torn between what crank i should use

Crank A(original) spun rod number 3

Crank B- rod knocked for 30sec on number 3, seller claims it jus needs a polish

Crank C- Number 1 cylinder lost compression, seller bought a new motor...says crank is good

Now which one would you get? trying to figure out which one so i can drop it off at mazworx on friday

thats what I would get, assuming the 0 compression was due to rings blowing out so that crank is still "good"

The others would need to be machined again thus $$

You could also consider getting a spool imports stroker crank, only 1700 AUS. NEW! :D

I'm in the same situation and I would go with C. I'm about to get the same thing, longblock with bad compression but no spun bearing/rod.

It's your call, I'd flip a coin. I would steer paying an extra 50 if the crank has no damage at all.
