setting up the rods on a 221
hey guys, so this is the first engine ive ever built with the floating brgs in it..
I need a little help with a couple things. first, the rods have L 1234 and R 1234 . but I don't see any difference in them, I was just wondering what makes them need to go on the left or right side ? and im thinking the right side, is the passenger side ? and 1 is gonna front most cylinder ? so how in the heck do I plastic gauge these brgs, ? and which way do the rods face, I really cant see any difference in any of them .. thanks guys ... |

Re: setting up the rods on a 221
The rods are the same, no offsets, they were marked after installation
You might be better off using shim stock to check clearance |

Re: setting up the rods on a 221
The numbers face the outside of the block where they can be easily seen. You need to measure the OD of the journal with the cap torqued in place and the thickness of the bearing. There is also a measurement of the spread of the bearing. Ol Ron's book "Nostalgia" does a good job of laying out the procedure.

I was going to recommend Ron's book as well. Woops, wrong book, but a good one as well. Second try. There, that's better!

Some might wonder why Ford went this way back then. Well is was caommon aircraft method in some v style engines. Now some bearings are lik the rear main with a thrust face. I don't use those early cranks. But I cut the lip off and use them in the 91 and 21 rods. Also you can buy bearings with a lrger ON by .004/.008. Done right and they last forever |

Re: setting up the rods on a 221
Just by chance I watched a video yesterday that educates a little on this topic. Mike Finnegan from Roadkill. The good stuff starts about 7:30 and goes to about 22 minutes. Be warned it's not a flathead, but measuring and fitting bearings is the topic.
