[6pack] 72 pistons

[Bob]

I was just removing the rings and cleaning the pistons for my rebuild when I
noticed on the inside of the pistons that there was an A/E on the casting.

>From what I remember doesn't that signify AE Hepolite?

Could these be the stock pistons?

They have the standard markings on the top a "B" + the indented arrow to show
which way to install.

Again,

The 6 is totally new to this 3 and 4 owner! Just a bit curious.

Thanks,

Bob
