I got these with a 383 in peices that I plan to finish building and run in my '93 Indy with P600 8psi twin cooler kit.

Contacted SRP and they can't tell me what they are since these were made before they started laser numbering them.

any ideas?

 

You should find away to measure the dish in cc's and the pin height and the diameter. you could also measure the top ring land, and weigh it, then see if it matches something in the catalog.

 

does not look like my dished srp's... but ditto on what keving said, check pin height and cc em

 

how long are the rods? if they are porbably eather -24cc if 6.0 or -31cc if 5.7unless they are custom based on the way they look id say they are 31s

 

The rods are 5.7 eagle H beams, after seeing your post I did a few searches for pics of 383 SRP -24 and -31 pistons they apear to be -31.
