I have the Eagle forged and the rods are 6.125. They come in the kits so it's nothing you'll need to buy separate.

Ultimately you can change the rod length if you wanted to. Most come with the stock rod length but also sometimes it will have a slight adjustment in length.
6.0, 6.125, 6.250 are possible.
If it is in a kit, the length should be listed in the ingredients. LOL
The pistons within the kit should not have an issue working in the block (height) or with the rod.

And one thing to think about too, your compression ratio is greatly increased when you put a 4" arm in there. So pay attention to the size of the combustion chambers in the heads you get and the cc's of the pistons. If you get a small chamber head, the CR will be really high with just a flat top piston at zero deck. You'd be fine with a large chambered head and flat tops though. The W2 heads on my car have small 51cc chambers and with Diamond flat tops it was just under 14:1 CR. Had custom pistons made with -25cc reverse dome just to get it down to 11:1.

I have a nice set of used Eagle I beam 6.123 rods. I have been stock piling parts for my other 67 Valiant that I will start on in the summer. I have a 91 roller 360 engine with a useable stock bore but I may end up boring it to 0.20 or 0.30. I grabbed the rods for $100 and figure all I would need is the crank and pistons to complete it.
What are those rods rated to?

51cc-W2's?!?!?! Wow!
Chamber picture by chance???

Are your w2's closed chamber or open? I assume closed since you said small chamber.

They are the std Eagle SIR 6.123 rods so I assume 4-500hp

They claim 500 hp and 6,000 rpm.

65 is the closed chamber head.
51 is really small.
My W5's are 59.

"Generic"?
I have seen some of the Mopar big-block strokers that have the rod journals ground down to 2.200 to use BBC rods ... do they do something similar with the Mopar small-block strokers?

When in doubt... floor it
Clints heads started out closed chamber w-2's and only got smaller! Haha

Yes, theres all sorts of combonations you can run. Mr bloomer sells cranks with chevy rod journal and 4" stroke and bigger and smallblock mopars. Its all in what your using the engine for.
Yes, AKA, Chevy rod size in this case. NASCAR set forth a must be obeyed law that you must use ..... and there is a ton of Chevy stuff listed. I'm not really big on it and what it includes. But there is a bennifit to this. You can get the "Gerneric rod in MoPar widths. These rods also come in various lengths.
Yes. But there made that way. Not modified.

I've been looking for some Mopar small block rods in the 6.25" length and all suppliers are just blowing off my inquiries. If anyone has a REAL source for this item please let me know.

You'll probably have to buy a 2.00" or 2.10" pin rod to get a 6.25".
Sure do. IIRC, they were 51cc when we first checked them and 53cc after builder did a little chamber work.
Chad Speier did the port work on them

I built a Magnum 403 (5.9L honed 0.005" over with 4" crank) for my 1995 Jeep Grand Cherokee. All-time 4 wheel drive, 3" lift, 31" tires, stock 3.92 gears, rebuilt 46RH transmission, Jeep is over 4100 lbs. Ran a best of 13.391 @101.74 mph. Stock computer wouldn't let it spin over 5100 rpm. All-time 4 wheel drive was fun, drove around the water box, no burnout with offroad tires and it would hook. Even in the rain on the street it would hook.
Bad machine work (you get what you pay for) and after a couple years the head gasket blew. Got it rebuilt its now a 408. its sitting in the Jeep right now but will be going into my Barracuda till I build a big block for the Barracuda.
