Na vs turbo 3.8 connecting rods.

Building a 3.8 Na 2bbl motor into a turbo motor with grand national parts
Does anyone know if the 3.8 Na motor got the same connecting rods as the turbo motors?

What year NA engine? if it has the 2 dots then you have the same rods. Only thing I have noticed is that turbo engines typically have SPS rod bolts where the NA rods do not. If you are doing a build I would install new bolts (ARP) and resize them.

That was my plan. The motor is an 85

some of them did. 763 is the casting number you're looking for.
