Well I got them here.
Dont think they are Jahns, but I dont know my piston history very well.
On the underside of the crown is stamped ANSEN and across from it is DIFC0513. Part number? could be a 6 instead of a 5
There are no other marks either stamped or cast in.
Piston-575g
Pin -175g
Diameter- 3.930 [ one is 3.931]
Pin diameter .9277
C/H -1.64
Total height 2.944
Standard rings 5/64 5/64 3/16
I have to determine the pin offset. Being for a v8, the offset should be backwards on 4 of them.
So 2 quiet and 4 power or 4 quiet and 2 power?
cyl 1 and 6 quiet and the rest power?
