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

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.Last edited by DaWizard; 01-20-2018, 07:02 PM.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

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

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.

by DennisI'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?

im tearing an engine down, and it has ford .045" pistons with center lock wrist pins.my 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,...

by DaWizardSomething 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?-

by poochDo 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...-

by SAJI 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...You do not have permission to view this gallery.

by DaWizardWell, 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!!
Now,...-

by tbirdtbirdPictured 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:...-

I under stand if you can not go bigger. But it sounds like some put sleeves in even if they have room to bore more.
