They look like 1970-71 E to me, God, could I use them.
Do they have 5 or 6 in the triangle above the skirt. Do they have 5 or 6 stamped in the triangle? See attached web site for comparison of pistons/ No affiliation to this site. http://www.bassant-parts.com/contents/en-uk/d4913_01.html |

QUOTE(euro911 @ Dec 20 2013, 01:47 PM)  I parted out a 2.2 long block for about $3,800 ... 30 years ago I shouldn't complain, I bought the engine for $150. and sold my old set old set of HEs for that much. Come to think of it, I think I still have some populated 2.2 heads in a box around here (IMG:style_emoticons/default/confused24.gif) ... I'll have to look (IMG:style_emoticons/default/idea.gif) I kept the heat exchangers cuz they were better than my originals Guess I should have kept it around for a while (IMG:style_emoticons/default/headbang.gif) |

SORRY, must put my glasses on.
But look at the piston top they don't look like T pistons the pocket appears to be too big. Or may be It just looks that way without GLASSES. |

Look at the piston comparison c/o Tom1394racing on the pelican site. pistons don't look like T to me, But then I'm half blind so who knows. Attached image(s)

I looked up the part # on the box that you have. The closest thing that I found with the part # was used as a 2.4 T p/c set (non cis). If you look inside the piston you will see some letters/numbers this will confirm what you have. Look at the list attached to see what you have. Your best bet would be to figure out what you have then list them on the Pelican site. I've had better luck selling 911 p/c's there. Yup, I knew that the stoke was different (66 vs 70.4) that's why I said that the bore is the same between 2.2 &2.4 other then compression ratio. Put the 2.2 pistons in a 2.4 engine and you get a few more hp. Good upgrade for someone that's rebuilding a 2.4 and wants a little more out of it. |
