EA82 Compatible Con Rods

[SuspiciousPizza]

I've been Johnny Cash one-piece-at-a-time(ing) everything I need to build a fresh EA82 and I've been stumped on sourcing connecting rods.

On several parts websites I've seen that EJ rods (P/N 12100AA310) are allegedly compatible with EA82 rods. However, the stock P/N for EA82 rods (12100AA011) doesn't show up in the supersession list. 

Has anyone tried putting EJ rods in an EA82? I've heard of others trying to get EJ pistons to work but I haven't heard of using EJ rods in an EA82. 

 

Thanks :]

I had problem with connecting rods in my ea81 motor I sourced an old  ea81 motor 

and got the conrods out. Pretty sure they are identical with ea82.

No, P/N 12100AA310 is NOT compatible with 12100AA011. None of the dimensions are the same. Too large of bearings and center-to-center distance is too long. 

Bummer. I hope I don't need rods or else I'm tearing into my spare ea81. I'm saving it for a TBI conversion.

That’s the era where they (SOA) really tighten up with dealer stock. Dealers are told to destroy parts or at least damage them as they throw them out. 
 

So finding 80’s and later NOS is more tricky than 70’s. 
 

But Carl Porter is the big man these days for NOS since I’ve been getting out of this habit slowly. He’s here once in a while. Find him in FB if you haven’t already.
