Title: 460 ford ring gap
Post by: 77Galaxie on April 23, 2016, 05:14:44 PM

What would be the proper ring gap for a 60 over piston rings? Attached are the Pistons I'm using.

Ring gap is determined by the piston manufacturer.  Contact them for their specs.  FYI, I just completed my 460 build yesterday.  Lots of good info here.

It also can depend on the engine, blower, nitrous, etc..

I used .0050 x bore size for my top ring and .0055 x bore size for the second ring. I ran Hastings moly rings and it's just an n/a deal. Also remember to measure the side clearance, and back clearance as well to make sure everything is fitting right.
