Are they + .005 file fit rings?

 

Since he got them from Barry they are +.0005 rings. You need a ring grinder for sure. I just did mine a couple weeks ago and it too forever. I may have been a little picky but I had around 8 hours in it.

Rods have a big chamfer like mentioned it stays towards the counter weights. Bearings also have a chamfer so pay attention there is a top and bottom. If you don't have it right they look like they are misaligned when the cap is installed looking at it. Pistons aren't marked for front so make sure valve reliefs are intake side. Another tip to keep your rods going together correctly when installed numbers on the rods go up toward the cam.

 

Also better check your rods and crank real good with a dial bore gauge. My crank was too tight so I had it polished to use the std bearings. The rods were too sloppy and needed .0001 under bearing both sides except the front journal for 1 &6 it took a std and a 1 under. I got the extra rid bearings from Barry because he was the quickest. I hope you don't need them too because those race bearings are about $85 a set.

 

Yes they are. I wanted to check before I said anything false.
With the supplied formula as a guide for filing, I decided on 20 and 15 thousands for the rings. Does that sound about right?

 

Great info!
I eneded up borrowing a filer tool from my machine shop in exchange for doughnuts and coffee. Took most the afternoon. What specs. did you go too?

I called it quits after that because I wasn't certain on piston orientation (as you mentioned) and I had issues with the oil countrol ring set.
Simply put, mine don't fit, and I don't understand why. The expander ring seems to be like four "waves" too large and same story on the rings that surround it. Is this normal? Do I shave them?

 

I would have to look but I think for the first ring .017, 2nd .022 and oil rails .015. That was what Barry said to do when I talked to him.
Also the oil expander never gets fiked and mine too seemed too large but once they are on the piston and have the rails attached you'll see they need to be like that.

 

If you do have to grind the oil rails be very careful with them they are so easy to move in the cyl and give a false reading.

 

Came out if a '65-'66 Galaxie with 1-3/8 shaft

 

Interesting, the formula sheet states bore x .0045 for first gap and bore x .0035 for second. Using this info, doesnt the first ring have a bigger gap and second smaller? Also the first ring would see note heat=more expansion... At least in my head.

Not trying to discredit anything you say by any means especially if it came from Barry, just digesting and making sense of everything.

 

Yea I hear ya. There was a paper with the rings that had a formula on. I shoulda compared it but I did what they recommended for a NA motor.

 

Now that I'm thinking about it, I'm going to do some more research to make sure I have what I want on the rings before installation (hopefully tomorrow). The sheet gave me a different formula for NA, 200+ shot of nitrous, gas's blown and alcohol blown.
I went just slightly higher than NA, because I was tooling with the idea of a small bottle hit (100-150 max) just for *****s and grins, without risking the build...but its just a thought. I filed for 20 and 15, but am tempted to go 22 and 17, because I'd rather have a slight safety margin than risking the rings butting.

I'm curious to do more research on the philosophy of which ring gets the bigger gap, I'll share anything I find worth noting.

 

Did you have to file the rails at all?
I ask because I know you've done quite a similar project, only with a couple more go fast goodies. Haha

 

Yes I did because I had literally no gap they were tight. They told me anywhere between .015-.050 for clearence on them. I went with .015 I couldn't see over doing it.

 

Mine were a "tight" .015 on the gauge, so I'm not terribly worried about them.

I got the blasted clips the hold the wrist pins in yesterday and started installing rings on the slugs. If I male it to the shop today I'm going to try to get them in the block.
I'm still slightly worried about the expander rings however.... They're tighter than... Well tight.

 

Haha on the circlips those things seriously suck don't they!
