[355/72camaro]

Hey everybody just bought a eagle rotating assm from summit. I guess I jumped the gun and didn't do my home work. Found out it's made in china and machined here? I'm just wondering if anybody has used them before and how they holdup? It's for a 355 sbc the assm is cast crank with fordged I beam rods and fordged pistons file fit rings. The motor will prob base at 420hp and I have a small 75-100hp shot of nos. Any info would be great thanks.

Did you do a search here? There are a ton of posts about rotating assemblies.

Most all of the affordable ( no matter what brand) cranks cast or forged are made in China and machined here. A fact of life.. Eagle had a bout with poor quality control a few years ago. About the only brand name I avoid is "Cat". I have seen/had some really bad stuff from them. I believe they are now out of business. I used to buy/regrind a lot of factory second Scat cranks so all have had a problem once in a while.

I have used several of Eagle's cast "steel" 383 cranks and have had no problems. Just have a machinist measure the journals for taper/round. These cranks are plenty strong.

Of the "imports", Eagle is the "premium" brand. The "fit and finish" is always a little "nicer" than others.

We've had issues with the cast steel small block cranks not staying "stable" at higher HP and revs (over 400 HP, 6,500-up). The forgings are MUCH better. Our '68 Camaro went 8.90s with a "300 shot" @ 150 using an Eagle 412 "kit" (3.8" stroke, 400 mains).

We use Eagle cranks almost exclusively for the Pontiacs. No comparison. Unlike the smaller Chevy cranks, the Pontiac is fine with a casting up to at least 800 HP.

We've seen balancing problems with Scat products, and it doesn't seem to be with just one or two engine "families", but a lot of their "strokers".

Eagle's H-beam rods are also a little "nicer" than the other imports. There's an additional feature not found in ANY of the others. The "third rib" down the center of the beam makes the rod stronger than the "rest". Two small radii are stronger than one large one.

FWIW

I had a problem with an eagle crank. No two journals were the same size. Off by a ton. The guy at eagle said "I'd run it, but I'll send you a new one anyway.". Funny, the second one was dead on, only it ate up thrust bearings. Repolished it, been okay so far. No more eagle formme after this one. I'll stick with GM steel.

What ever I buy gets checked before anything else is done.
