  • Do any of the piston manufactures make pistons that take a modern narrow rings.

    Narrow rings in IMHOP work better than wide rings. nWhat do you think.

    I have only dealt with Forged True pistons in a racing Flathead V8 and I do believe we ran cast iron rings that if memory serves, were Hastings. Now, I don't remember if they were the wide or narrow rings, but I would bet that Forged True only makes the narrow ring pistons for flatheads.

    You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

      I used Hastings piston rings for yrs. Never had an issue with them.

        I agree they work fine. But narrow in mhop work better. When the piston rocks the narrow ring seals better. A wide ring lifts off the cylinder more, so more blow by and less oil scraping. Maybe not enough to worry about.

          George, I am with you all the way on narrow rings. If wide rings were so good, moderns would have them.
          I happen to really like the 283 style pistons that I get from John at Pete's machine, who has Egge make them. You use std A rods and pins. His pistons come with the rings and pins

          Way in the beginning of the VFF a question was asked about the weight difference and I weighed a Snyder's vs one of John's and Johns weighed a little less. I think you have used these same pistons at one time. I am unable to find that post right now, and I do not recall the weights, but the 283 style weighed LESS

          Oops, Al just commented on this above

          Here is another thread on the subject

            Yes I did use some of John some time ago. I think I will go that way again. I though some one else may have them also. I do like the 283 piston. To me cam ground piston are much better than regular A piston. And they do use the narrow rings. thanks.

          George, Rich Falluca uses the narrow moly piston rings. I was concerned about the moly rings taking longer to seat, but have found in my short block I had him build this past fall they seated sooner than the Hastings cast rings on my stock Model A pistons. Prior to having him do the machine work on my block, it had a 6:1 head with stock pistons .030" over, with wide Hastings cast rings and leaker silicone head gasket from Snyder's. It had 100 psi in all four cylinders. The only reason I had initially to machine the block was for inserts as I had over .025" crank end play. Now with his pistons and narrow moly rings, forged rods, same 6:1 head and a Best 573 graphite head gasket, the deck of the block was cleaned up, compression is even in all four cylinders with 120 psi. Maybe the rings fit the pistons better than my original Model A pistons, but so far the oil is nice and clean and does not use oil. Falluca gets his pistons made in China btw.

            Dennis, I am with you, I am surprised that moly seated sooner than cast

            impressive numbers you give......

                4 ring pistons
                by fmr187
                Getting back to an old project I have broken down an model a engine I picked up years ago. The pistons have 4 rings. All the catalogs only supply 3 ring pistons. The pistons and cylinders look good so I want to reuse them but I cant find any parts listing for 4 piston rings anywhere. Can any one help me locate a supplier? At the moment I dont know the manufacturer of the pistons. The engine was rebuilt...

                3 ring pistons
                by Dennis
                I've heard of this in the past and might have seen some pictures, but as far as I've been able to find were rings for pistons with 2 grooves and the oil ring. Anybody know where to find rings for a 3 ring piston?

                Repro vs original design piston rings
                by Mrtherich
                Are the piston rings of the repro piston head designs interchangeable with that of an original design with the same diameter?

                I have piston heads of this design type with 0.010 oversize. (Picture from google, not from my actual pistons)

                But the rings on these pistons need replacing.

                The problem is, the webshops in my country selling reproductions,...

                Old pistons
                by Chuck Sea/Tac
                im tearing an engine down, and it has ford .045" pistons with center lock wrist question is regarding the rings. The upper slot has a .012" spacer so it can use the same size ring as the middle slot. Yes, different size slots. The middle has one inch pieces stacked underneath the ring, so as to push the ring tighter to the cylinder wall. Whether these were originally one solid ring,...

                Reseat rings
                by DaWizard
                Something has been troubling me today.

                I can't remember if I heard or read something about reseating rings in a somewhat tired engine. The use of baking soda or borax or a gentle abrasive as such would reseat the rings in a tired engine.

                What, if anything have you learned or heard over your lifetime about helping out a tired engine?

                Rings moving
                by pooch
                Do piston rings move around the piston in normal use?

                Like, if I take care to set gap positions all correctly, is it a waste of time?

                I once read of a guy who said it was imperative to set the top ring gap directly opposite the exhaust valve , then I think he said set the next gap at 180 , then set the oil ring gap upwards (on a V8).

                What do the...

                Piston Expander. "Koetherizer"

                I posted this on "another"forum in response to others and thought it might prove interesting on VFF
                "I have a piston expander called a Koetherizer. Invented by Emil Koether in the Early 1930's. You clean the piston internally by blasting with walnut shells in the right hand chamber of the machine. Then insert the special squeeze bolt through the gudgeon holes, tighten the bolt...

                Well, got the pistons and con rods out of the block today as I am finished for now on the "craft shed" for the kidlet.

                Much to my dismay, none, nada, zip con rods have shims on the big ends!

                There is also something I have not seen before, pistons with not just one compression ring, not two, but three compression rings!! Plus the normal oil ring!!

                If pistons could talk....with pix
                by tbirdtbird
                Pictured on the left is an old school Model A piston with an archaic design from the '20s, '30s, '40s.
                On the right is a Model A piston of modern design, a design adapted by all car manufacturers many decades ago. The skirt is short and the rings narrow. Inspect the features of the two yourself; you need not be an engineer. You only need common sense to answer the following 3 questions:...
