Has the QC on 440 Source cranks improved? - 03/26/15 10:41 PM
I'm thinking about building a stroker and would like to know if the 440 Source cranks are better these days for grinding precision (taper and runout) than they used to be. It would be a low deck stroker with a 3.91" stroke and not many places even offer a crank like this that I know of.

I have low deck Molnar 3.91 cranks in stock. If you are East coast,shipping may be a little less. If your West coast, then maybe 440 Source would be closer. Let me know if I can help,otherwise I am sure Brandon can help you out.

I built a 526 stroker and the crank was fine, runs great.

I've used several 440Source cranks over the years and have never had an issue with them. If money is no object then I use Callies, but most people have a budget that doesn't allow all premium parts.

I just received a 4.25" as part of a stroker kit, according to my machine shop the grinding aspect of it was great. They just took a tiny bit too much on the balance.

Same for me, my 4.25 crank was awesome, checked by my engine builder. Came out real close grinded a tad nothing serious

No problem with mine - which I bought about 5 years ago.
The tales of bad cranks seem to have been rumors perpetrated by people who had no actual first hand knowledge but are just down on products made in China.

I never heard of 440 Source being out of tolerance. Mine was checked and found to be right on. Still running strong after about 300 1/4 mile passes. Back when I bought my rotating assembly , Brandon was taking all kinds of flack from the peanut gallery for selling off shore stuff. As stated above, I couldn't afford Callies

I'll go a step further. You never run any stock or aftermarket internal or external part without a thorough check. RIGHT???

i got one last year. i was told by the engine builder it was good but on the large side of spec. so he got .001 bearings i think. other than he said it was freeking hard to drill for balance he said good to go.

i have a winberg,zero problems there.but everything needs checked.cheap,expensive,new,used or whatever.lots of reasons many companys can make mistakes. mistakes are never intentional.check and recheck and sleep well at night.

I have had (2) 440source cranks that checked out good but my 2200 dollar Calais crank that I got off Indy for my 572 was cut .010 when I bought it. Brand new in the box crank.

every once in a while,ohio gets a batch that needs remachined,but they tell you that in advance and discount them accordingly.usually they are sold at .010 under after they make them right....

I just got the first 440 Source kit in my shop--
Here is what I found:
Pistons were a dish no one else offers except order and wait so they were a Bingo!
Crank was on low side everywhere--so she turned like hot butter another BINGO!!!
Rods ehh...honed pins to fit like normal
Big deal is the crank seal area--It is SMOOTH like they SHOULD BE!! I am done with the "hash mark--deep gouge"-BS on Eagles! No more Eagles in this shop with that mess back there--They need to SOBER UP!! and quit doing cranks that way like it is 1962.....I think they are idiots for keeping that up
So...I am impressed a backyard guy would come out fine with what I recieved after he pinfit the rods --they also mentioned that when I ordered!!
Think they should go ahead and do it for folks to improve their kit but ......silly not to--easy way to imprve their offerings--
Me likey so far....
