... Are you building a stroker or just getting that ticking bomb swapped out?
I did ask them if they where Chinese imported forging that they(Ohio) finished and sold as "American" and they said absolutely not, all of thier forgings come from Ohoi Forge, 100% made in America 
the one thing I did find on the first batch I bought was the heat treating, they where a # 25 or 26 Rockwell when I had them tested. My crankshaft grinder thought that was a little soft and had me have them reheat treated I don't know what a good heat treat number is for a forged crank Maybe some one who knows will chime in with thier recomendations 
checked out by my brother. 35 years as a QC guy working on Jet engines. He Mag and X-rayed and said it was a better forging than most of the aircraft parts he worked on.

Call around and see what the professional engine builders are using. I'm always surprised when I make a few phone calls and hear what people have to say.

I'd have to call you pretty experienced, Andy. What say you?

But I was a little surprised the other day when talking to a serious engine builder who was using Eagle cranks and rods in lots of builds.

Cab i'm not trying to start any "discussion" if you know what i mean but imho there's NO way they're selling a american forged and machined crank for $600...just not happening. not that an import forging won't do the job (for many) and certainly surpass the oem piece if properly machined. i just don't see a 100% USA crank going for 25% of what others cost. of the imports i was under the impression eagle's stuff was "supposed" to be the best? obviously the leading problem with imports is the machining. i believe the callies compstar line is machined from imported forgings but they don't offer a bb chrysler crank.

I bought a brand new Eagle crank and had to have it turned.

Quote:I bought that crank about 4 years ago and its still in the engine and doing fine now. When I took it out of the box I checked it and had .0007 taper and .0003 out of round on the worse rod journal and was way up on the high side of specs so I did not have enough oil clearance either.Quote:

How long ago ?
Why didn't you just SCRAPE your bearings ? That seems to be the ACCEPTED practice for many ?? ... that was said sarcasticly ...
I bought an Eagle Blem for the EM470 project , got it from either Mancini or Muscle Motors , can't remember , it was cut .010/.010 to fix the wonderful Chinese finish SAND JOB. DRAM then cut it again to fit a 400 block AND increase the stroke , funny part is no scraping of bearings to make it fit ... something must be wrong ???

Quote:I am very picky. I also ran a crank grinder every day for 12 years and I would have never let a crank leave my shop like that.Quote:Quote:I bought that crank about 4 years ago and its still in the engine and doing fine now.

you're way too picky , the king of the bearing scraping crowd would have called that good

BTW, I was talking to one of the local Mopar racers this afternoon at coffee, he discussed a post on here( I think on here, general forum maybe ) about some SB RHS iron heads that a member had dynoed on a 360 magnum type street motor and was very pleased with those heads. They are around $800.00 complete and there 100% American made according to the engine builder. I think two heads with all the assorted parts would cost more to machine and make than one forged steel crankshft, metal is metal, it's all sold by the pound from the factorys. Steel costs more than iron, aluminum costs more than steel
