[SOLD] 273 Commando Pistons

[SSVDP]

I have kept this set of 273 "Commando" pistons for a few years but it doesn't look like I will be using them so I figured I would offer them here for $120 plus shipping ( they should fit in a USPS medium flat rate box for $13.60).
These pistons I were used on the Plymouth " Commando" & Dodge "Charger" 235 horse power high performance versions of the 273 V-eight engines with 10.5:1 compression ratio ( in reality probably not that high but higher than the two barrel version).
There are four pistons which are part number "661" and all have a "C" stamped on the top; There are four pistons which are part number "658" and three have a "C" stamped on the top & one with a "D".

standard bore?

 

[SSVDP]

I have not measured these so I suppose it's "standard bore".
I think the "C" letters are piston sizes used during plant assembly.

Hey? What happened to my pics in first post?
Here they are:

Can you measure bore? Also pin bore?

 

[SSVDP]

No, I have no way to measure these.

Those look like stock pistons. If they were oversize they would be marked on top. Being as how they are not marked on top, probably means they are standard bore
TThey would be good for rebuilding a nice original block.
TThose are factory hipo pistons.

They do look to be stock bore and from what I have read the original pistons were 10.5 compression and the aftermarket ones being made today are further in the cylinder bringing the compression down about to around 9
