Technical Jahns Pistons

Can anyone tell me the application for these Jahns Pistons? 1136 HRP ,060 4.050 is printed on the box..Thanks for any help...Mac

 

Mac, looks like there is another part of that number in front of the -1136. Any chance you could read it or is there more information in the box?

 

I bet if you took a picture of the actual piston a HAMBer could tell you what it fit.

 

Do they look like this?

 

Look like chevy 302 flat tops.....

 

I think it is an 8 which is the number of pistons....pictures attached....these are 12.5 - 1 compression

 

283 .060 over?

 

No such thing!

 

Dosen't a Ford FE have a 4.050 bore? Dome looks like gentle dome early 427 pistons.

 

4 -1/8 = 4.125 bore.
AH ****, you have us trying to figure out what a set of pistons on Ebay are eBay item number:364583035691

 

The 390 is 4.050" bore standard. So does the 360 Ford FE. Difference is stroke.

 

I had to use all of my cheating skills on this one. LOL to the guessers..
They come out as Cast 61/68 Ford 390. From a page in the 1969 pfd of the catalog that this gent selss for 9.95. He has a bunch of PFDs of old parts catalogs for sale. Jahns Quality Racing Pistons 1969 Parts Catalog CD Rom PDF File | eBay

 

I bow to your superior knowledge.

 

I didn't have my decoder ring on when I searched though the listings for the pfds of Jahns catalogs that Oldspeedtees has listed. I was just happy to find the listing at all as he doesn't show Chevy pages or many others and I searched by number going from catalog to catalog.
I went back and checked each listing and one has some decoding of the letters but doesn't show what H means.

 

I would guess it means high compression

 

Thanks for your help

 

1136 was either Ford 390 or 406, depending on the bore size.
