Not sure if the right place to ask this question, but I tore down a engine I had laying around and the 12A irons are ported (not bridgeported). I want to list them on the classified section but they require me to list a price.
Not sure where to price range these.
Any help appreciated.
It had 13b housings which I am keeping for my SE.
Thanks.

 

Street port?

 

clear, detailed and if possible, scaled photos would help get useful responses to your question on pricing.

it's a safe assumption since he explicitly said it's not bridged.

 

Yeah I should have thought to post some pics. I'll take some tomorrow and post them. Definitely not bridged .

 

Ok, here are the pics. I was thinking maybe $300 is a fair price?

 

i see step wear. will definitely need resurfacing.

 

^^Especially on that last pic.

 

OK, so is $300 too high if it needs that? listening to what you are saying , so then what is a fair market price if they have to do that?
I'd like to get a fair price for both the buyer and seller but don't deal with the ported stuff too often. That's why I ask the experts.

 

Ok, trying to educate myself at the same time here ....
So, also wanted to know what would cause this. Is this a clue to look at possible wear on other parts that came out of the engine?
I was thinking about using some of the other internals on a rebuild.
The 13b housings surfaces look like new.
So, what else should I look for?

 

Stepped wear is a natural result of engine wear, made more or less severe by amount of abuse, quality of lubrication, bearings, fuel mix, and a few other variables. Run long enough all rotaries develop stepped wear on the side plates due to the engine design, just like boingers develop ring ridges in the cylinders.

Grab a copy of a shop manual for SA/FB's from Sgt Fox's site, and a micrometer, feeler gauge set, gauge block (or dial gauge and float plate), and do the inspection measurements listed in the engine rebuild section.

Until you know the current thicknesses of the irons and the amount of stepped wear, there's no way to tell if they are junk or gemstones. The difference is the matter of a few thousandths of an inch.

The fact that they are ported may increase or decrease the value for any particular buyer (and the quality of the port job, which can vary madly from amateur to pro), but if the irons are too worn to be resurfaced without going below minimum required thickness, they are essentially scrap iron, worth nothing.

If they measure out as having useful life left, then their value is driven by how bad someone wants or needs them.

It doesn't help their value that it looks like these irons have been sanded with coarse-grit paper in an attempt to get rid of some burn marks/rotor strike marks.
