[Found!] ISO standard bore 340 Pistons from 71 or earlier block

[Jim Ward]

Budget build on a 72 340 and would like to replace the 8.5:1 pistons with 10.5:1 from the earlier 340. Located in Michigan. What is available? Picture is of the low comp 72 piston currently in my motor.

You should be able to find a set of used stock Mopar slugs...

 

[Jim Ward]

Yes that is what I was hoping to find.

thanks Jim

These are available if interested.

Those look like the OE 72-73 pistons at 8.5:1 compression. What is your asking price?

I have a set of 8 Custom Forged Diamond Pistons 4.06 Bore, 10.5 compression
(compression distance 1.910 1/16, 1/16, 3/16 ring pack .927 pins)

I have a set of 70's that are out of my race car when it was new
and nice shape with pins = you must use 340 floating rods I think to
use them (not sure)
$100.00 plus the ride

I'm on the opposite side of the "fence", but if you can figure a way of getting them to you, they could fit your budget.

Thank you to everyone who commented. I was lucky enough to find some locally within budget and are already installed on rods with new rings. There will be more stuff needed for this build.

thanks again.
