340 Piston Selection

It says right theee on the page, “We also have other pistons sizes.” So call them up and ask a few questions and answer there’s that they’ll ask you like, “How many cc’s is your cylinder head?” Which you didn’t tell us.:rolleyes:

What ratio are you looking for and with what head and cc amount in the chamber.

The tech line should also ask you this exact question along with a few othwers like, “Are you going to run NO2?”:D
65 CC Rpm heads they are new and I just dropped them off at Killians Porting Service in Warner Robbins GA have heads ported and tunnel ram port matched and competition valve job done . Im building a 340 for my 51 Henry J gasser to be raced not street legal so I need compression.
