Im using a connecting rod from a differant engine, and the crank will have to be turned, so Im assuming Ill need to get everything balanced. It doesnt appear to cost much, ~$200. Worth it?

I would say go for it if the funds are available, more reliability can't hurt.

Thats what Im thinking. Its not reallty a performance thing, its more about a quality rebuild

A balance job is always good sense if it does not break the bank.

I don't think having the crank ground affects that much - but certainly using new connecting rods does.

It really comes down to whether you plan on "pressing" things or not - RPMs here.

You could just throw in some rods and get by so long as you are not revving the thing much - else if there was some gross difference in the mass from one rod/piston combo to the next you might eat your crank with near max revs.

If I was paying to build an engine from the bottom up - all the parts and machining - $200 would not mean allot for the insurance policy.

+1 to what Klapa said. With the rest of the money you're spending, this is cheap insurance.

It's not just insurance, having a balanced rotating assembly will help smooth out the motor, prolong engine life, etc. It's definitely worth doing if you've got it apart.

Is that for flywheel, crank, rods and harmonic balancer? If so that is a damn good deal. I think I paid around 200.
