ZZ502/502 rotating assembly with about 140 hours on it .... steel crank, JE/SRP pistons, shot peened rods.

Crank has a very small "gouge" on one of the journals. Engine guy said it looks like a small piece of "something" got to it one time. He said it could be run as is, but recommends turing it .010.

Pistons look like new. Rods are in good condition.

I'm kinda thinking about going 540, and cost is a factor. Any idea what the rotating assembly would be worth ?

Thanks -

What happened to the zz502? I am putting one in my boat and curious if you had any problems with it.

As long as the crank is servicible Kidnova I would think 50% of the cost of new would be fair. That is generally what I shoot for when selling good used stuff.

I may be interested in it but only pay 25% of new when buying )

I want more hp and I'm in the process making build decisions.

No problems at all with my ZZ502. In fact when it was disassembled my engine guy said that it looked great inside. I've yet to hear of a mechanical failure in a ZZ502. Like any engine, good oil, changed regularly (+,-20 hrs. for me) and I expect it will be good to you.

Get a 540 crank and rods for this block and you're off........Sell the old crank after having it turned.

+,- 1/2 the cost of new is pretty much the way I was thinking.

25% huh.....

Thanks

I think the used pistons have close to no value, a damaged crank maybe $200-300 and used rods $200-400.

Why wouldn't the pistons be worth anything ? Never sold any before so just wondering.

Thanks
