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 ???

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 thought the same thing but I didn't want to start that bottle throwing ...

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.

The first eagle crank i purchased was 5-6 years ago, back then there wasnt vendor after vendor stocking cheap china Cranks. This crank was $900 and when we checked it, it had taper, out of round, and was at the highend of the tolerance scale. This would have put the rod bearing clearance near .001..So we decided to grind the crank and fix a few things at the same time. This didnt make me all that happy, but i knew at this point it was right..That engine just currently gave up the ghost. But after 100's and 100's of passes in several diff vehicles, thousands of street miles accumulated when I had it. It has been serving its purpose between the rails of a Mud pit racer truck now for a few seasons. He split the block and trashed the entire engine.  Those cranks are tough. I once seized two rods smoking the bearings and rods..The crank was turned and run hard, this happened near the beginning of its life.

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.

JamesSC, no offense taken, I was repeating what I was told by Gary at Ohio Crankshafts back in 2002 or so.  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

AFAIK the RHS's are cast in either Austrailia or New Zeland. IIRC most of the lower end valves are from Brazil...
