Outer Limits 4x4 Board

Has anyone got a comparison of sizes of conrods for the TB 42, 45 and 48 engines.
I know the 42 ones are beefier than the 45 ones but I'm after pin to pin sizing and a comparison of small end and big end sizing to see if there is any difference between all three engines.
The info is wanted for a guy I know who is looking into getting H beam rods built to suit at the moment TB45 but wondering what differences (if any) there are particularly with the TB48.
Regards Andrew.

Crower make a billet I beam rod to suit the tb42/tb45. 42/45's have the same stroke, and a rod length of 6.552".

Carillo make a H beam rod to suit the tb48 that is 6.437" in length.

You might want to check with those manufacturers as to the big end bore and width and the pin size.
