Is it 1.5 or 1.6? Or something different?

Thanks

You need to talk to Gary Baker, I'm sure he has that info. He watches this site so hopefully he'll pop in.

Thanks mEL, already talking with Gary. But didn't want to bother him since his wife just came home from the Hospital.

Yes, I'm in touch with him also via texting and am aware of his situation.

I have done a lot of work on those engines but mostly in a rebuild situation and never got technical as far as ratios were concerned. I see that one of the builders advertises ratio rockers for the 504, maybe Murphys ?? They should fit most of the big engines. I hope to be having DC roller rockers for one of my own projects if I ever get to it.
