I bought a 273 engine and auto tranny for 200 dollars. I removed the heads and was glad to find it had original Mopar .030 pistons . I'm not selling but was wondering how rare these pistons are and what they are generally selling for.
How rare are 273 Commando factory pistons .030 over ?

If you need one they are rare.
Once they are inside and running…. Not at all.

I don't see any rarity, since Egge has offered them in many sizes for a long time. Do they sport a factory Chrysler part number?
I'll look for a part number. They are definately Mopar and they are not available anywhere else that I could find. These are the domed pistons in a Commando engine.
They shouldn't be classified as "rare" . No need to make them something they're not. They are just a +.030 273 piston. I put them in my 273 when I rebuilt it.
Were your's Mopar or aftermarket ? If you consider them not rare can you point to a source for these ?
Egge has them all week long and twice on Sunday. They are good quality aftermarket, not Chrysler, though. What makes you think they are factory?
I'll try to get a pic of them as it's been a while since I researched them. I do remember that you could at one time get them from mopar but they quit offering them.
I always loved that Chrysler made the 273 a quench engine with those pistons. I wish they'd done the 340 like that.
Yeah, those are not the Mopar factory ones.
Yes, and like all the rest from Mopar, they were likely made by TRW.
Yep. I don't get it. What's the angle here? +.030 pistons were probably available at the Mopar Parts counter back in the day. Rare? Why would that matter unless you are trying to sell them to someone and command a big price.
I'm sure you could buy them from Mopar back in the day. The HP 273 was only produced for 3 years so they didn't make them long.
TRW part number is the same.
Thanks for confirming that. I thought that was the case. I've even seen TRW pistons with the pentastar stamp right on top.
I guess that's what's goin on. lol
I believe you are confusing rare with collectability. Your not going to come across them every day. That said, they are not new old stock in original boxes and they are USED 273 pistons, not Hemi pistons.
There is an *** for every seat and you may find a fool to throw alot of cabbage at you, but IMO, it's a foolish endeavor.

.030 273 Mopar pistons are probably fading away but still out there. I'm not sure what value could be added to be original Mopar over the counter replacement pistons as they would be inside an engine and no one would know or probably much care. There are still a few companies making pistons for a 273. The real deal would be finding forged ones.

As far as I know the original slugs were cast.

Agreed. I'm trying to convey any 273 piston that is still offered as forged.
TRW may have made them. I don't have my catalog yet. It's on it's way.

we are building a 273 with a D66 dual quad (which we finally found here) thanks FABO. If you find they are offered forged please post that. The pistons are the last piece to the puzzle to add nitrous.
I'm almost sure they did Mike. We built one in the 80's with TRW pistons and TRW Clevite bearings. It was a nitrous application.

My rebuilt 273 has .030 egge pistons. Work great, weren't hard to find or get.
2 barrel pistons but yes, not all that hard to find if you know where to look.
