OK.... Got my rods back from the machine shop.

Anyway one of the shops customers may have a partial used set...same dome same application. Waiting to here from him. If I don't get a reply I'll call RaceTec...
Or you buy a new set of 8, and let one of us have 4 of them to do a 170 ci slant 4. Block off half the cylinders in a 340.... like the Ponticc 'half-326' from 55 years ago... crank balance would be a bear though LOL

I have 3/4 of a set of high compression 4 banger pistons on the shelf from over 30 years ago... never found that missing 1/4 set.
