Mike, for some reason, my photos that are stored on Photobucket are not coming through any of the websites that I have posted/linked them, past or present. Cannot view anything stored on there.

I think the taper was .0005 and the clearance was .0025, but don't quote me on that yet. I would have to go out and see the paperwork in the box again. I did ship a piston and a set of rings down to the boys at Felts Machine (almost 5 hours away from me) in Suffolk, VA, where they are working my block over. Made copies of all of the documentation.

How do they look? I think they look GREAT! But what in the world do Y know? Sometimes I think I'm still a rookie, although my new cam and lifters went in great with no problem...if I could only talk my father in law in to letting me put that supercharged engine in his club sedan....

EDIT: links now back up...dont know what all that was about!

Daniel, how do they look?  I'm curious, what do they recommend for clearance?  My new forged popups should be in the mail coming this way, now .  The sonic test on the 312 block showed it good for the .060 OS, with a couple cylinders requiring a little offset boring.

FWIW, I just received a set of pistons from Speedway (30 over 312), and the set was made by Egge. Had all their packaging, stickers, etc in the box...they are flat-tops, going in my C2AE 292-312 build (eventually)



Time has escaped me these past 3 months!

John, the rods will be the 312 replacement rods you sent 3 or 4 weeks ago.  Thanks for the good news on the pin location.

Mike, the forged pistons have a pin ht. of 1.785". 

Measure thr rods you check the deck with. I've seen .014" variation in used rods due to factory tolerance and the number of times they have been resized. They get a little or a lot shorter everytime time they are resized.

yes i always check the gap.i cant remember what it was but it looked good in the cylinder.these pistons have to be made for .040 rings.

John (Ted Tim or anyone), what is the piston pin height (compression height) of the forged dome pistons, and plus minus variance?  Using the new rods and one of the .040 OS pistons that were in the engine, I should be able to figure out the decking required.

Did you happen to measure the ring end gaps on that build?

i had a set of these in a 292 truck engine i didnt know they were 312 pistons until i happened to measure the bore.i just used a set of .040 rings.what else could you do.

I've seen a number of 312's rebuilt by Ford reman shops with .0425" O.S. pistons. Where did they get rings for those pistons?
