[quote=Rallye469;30934]Huh?
Stock 455 rods are 6.735", stock 425 rods are 7.0"
If you think that the extra .265" of rod length are
there for compression reasons...your wrong.
Compression ratio MAY be a bi-product of all of
this depending on piston choice and it's compression height.
I don't quite understand, correct me if I'm wrong but if your going from a 6.735 rod to a 7.0 rod wouldn't you be moving the piston closer to the head reducing the cc's of the combustion chamber therefore the compression ratio would be higher? I also understand if you use a piston with a different compression height you can accomplish the same thing, either way your not getting a stroker motor by switching rods.
