Depending upon when this question has been asked in the past, the opinion of Ohio Crankshaft's Mopar cranks have coverage the range from to .

So, what's the latest perspective, or - better yet - recent experience, w/ their cranks?

Well, I have one in my 572. The short block's going in for a re-do here in a couple days. I'll let you know what my machinist says about the crank. It has about 200 hits right now.

Brad , Anything that is not a stock type 1053 forging should be good. Are you building a stroker or just getting that ticking bomb swapped out?

seriously , any of the low cost offshore forgings NOT finished machined here you should budget in getting it cut .01/.010 to take out the taper, you should NOT have to scrape a bearing , period .

Common sense says I should simply plan to replace the OEM crank w/ a better 3.75" piece, since it's only a matter of time before it cracks.

The problem when looking at new cranks is that the INITIAL cost of a 3.75" part isn't any different than a 4.25"... It's only when you start to factor in the "butterfly effect" that the REAL cost of adding those extra cubes starts to become clear.

I have a Ohio 4.15 forged crank in my 499 Challenger. I have fun it for 2 full seasons running two classes a night and have around 600 passes on it. Will be pulling the motor this winter to check it all out. I am very happy with it and it needed zero extra work. Best e.t. is 6.01@112.25 in the 1/8th at 3300lbs.

Brad, I have sold a lot of the Ohoi stroker cranks for Mopar BB motors that are mild to wild. No come backs yet 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

I had my Ohio 4.25 purchased through Cab 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.

I have a 4.15 Ohio crank in my HEMI and so far so good.
The machinist liked it and he builds Pro/Mod motors!

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.

5 years on an Ohio 499" kit. Lots of miles and lots of passes, no problems. I'll buy my next kit from them.

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

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 don't have any experience with Ohio stuff myself. 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. They said the stuff was working great for them. These are guys who make lots of power, not NAPA rebuilder type motors.

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

i was thinking from what i've heard they're (eagle) probably being used in a lot more engines than people realize and as you mentioned we're not talking the "run of the mill" lower HP applications. i wonder how you could ever identify and/or find out exactly what forgings are coming from where as far as the imports and who's using them for cores. it might also be worth noting that as things develop overseas there is the potential that the quality of these pieces will improve. it seems like any other situation they have their differences in quality, ranging from "you really don't want this one" to "this will survive some noteworthy HP"

Don't you think the ohio crank, cat, eagle, 440 source, scat and other cheeper stroker kits basically are from the same forging place?

possibly the same country but i would "think" like anywhere else there's different manufacturers forging them with different levels of quality...who knows, i for one sure don't
