I have a set of used Speed Pro L2323F30 forged pistons for sale. Pistons have approximately 1500 miles on them. They include the rods but unfortunately I lost the caps. They are in great shape otherwise. I'm looking for $125 plus shipping or best offer. Here's a link from Summit for the pistons.

What compression are they ? Maybe it's list in the dad but can't see it

dfire25

Good question, I don't really know. What I do know is that I have these exact same pistons but 40 over in my current engine and it's 10-1.

They look deep dish in your pic can any one verify compression I have a snag on some stock ones now nut this could be better depending on what they really are

I have a set of rod caps I can throw into the pot. I just got a core engine into my place that had some bent rod pins from detonation.

dfire25

They are definitely not flat top pistons, nor are they stock deep dish. I can take a picture from the side if you like to see the depth. I also have a 455 stock piston I can take a picture of as well to compair. The stock piston is REALLY deep compared to these. Plus there forged, so they hold up better.

Thanks J!, I don't live too far from J, so I could pick the caps up and ship them all at once if you like.

If he's using the same pistons, this is what Brian is getting in compression. Estimated or actual I don't know.

His is +40 over

and then the rods should be checked and/or reconditioned

dfire25

Just noticed that.
Should be the same compression regardless of bore size, shouldn't it? I was trying to find some posts with simulare pistons to find compression ratio. If your looking to be above 9 these should be good, but I'm no expert.

Definitly

Try sticking them on Racingjunk.com.

Thanks my next option, or eBay. Thanks

These are a good deal for a driver build
Didn't find anything bad from asking around on the brand except in a high performance build they are a tad heavy

I wish I new if I could use them but I haven't had my block checked to see what I need to bore it to if at all

Are these still sitting around by chance?

dfire25

Yes I still have them for sale.

my72olds

Wht is adjusted price ? I'd like to have them for a street build looking for 9:01. -10:01 anythings got to be better than these stock 72 pistons . Let me know thanx

dfire25

The adjusted price is $125 plus shipping. Shipping is a little expensive since the box is about 40lbs. I can look up shipping for you if you give me your zip.

coppercutlass

Are these for a 455 ? I might be intrested but I might need a month or so but I'm building a 455 in the near future.

johnnyjaws

dfire25

Yes they are for a 455. Local pickup so you can save on the shipping

coppercutlass
