Hey guys, small engine builder here in Kansas City. Name is Mike Mac.
Building a 455 mill for a customer. C headed, hydraulic roller with hopefully the new RPM intake and a 850 holley. Street car. 72 cutlass convertible. Should be a nice build. I am interested in a set of 425 rods. Could be aftermarket around 7.00 inches. I am using a custom piston so I can use whatever I can find.
Thanks for all of your help!
Mike

 

Check with Dick Miller Racing. I think he still sells 7" BBO rods.
If you have your crank ground with Chevy-size rod journals, you can use an Eagle 7.1" BBC rod with a custom piston.

 

Here's another option that uses the BBO journal size:
