paid speedomotive 7k for a dart big bore 427 shortblock,had to send back the rotateing assy so they could cut the counterweights to clear the bottom of the pistons properly,noticed that the thrust journal on the crank #3 had benn welded and machined,called and compained thay said they do it all the time,after i did some CSI on the part #'s they started out with a 351w crank,turned it down to the cleveland mains and welded and machined the thrust journal,and the crank was knife edged to boot,that i paid extra for.i talked and complained to GORGE who i guess is the owner,he said send the crank back and ill reimburse you,i said can i get that in writeing,he said WHAT THE @#$K,ARE YOU KIDDING ME,IM THRUE DEALING WITH YOU!!,wont return my calls wont have any thing to do with me.all i wanted was the RIGHT crank in there not some wittled down piece. so guys buyer beware.

What's wrong with welding and then machining to get the thrust bearing to fit right? As for the counterweights not clearing the pistons, that is something they could have easily mocked up before sending it out... and should have.

they started out with 351W crank,not the cleveland crank,they took it from 3.00 mains to 2.75 mains,then they added material to thrust journal,then ground it to the cleveland journal width,i have blueing on the crank on the #3 journal,this was a nitrated 4340 crank.

Speed-o-motive strikes again.

Friend ordered a 400 Chevy short block. 7 pistons were d-shaped dishes, the 8th was a full dish.

Another friend ordered a 456 stroker kit for this 400 Chrysler. Balanced rotating assembly. I apparently put the crank in perfectly when we plastigaged the mains, because when we actually put the motor together, the counterweights hit the block. And on these motors, putting a 440 crank in a 400 means that one counterweight needs to be cut down for clearance. A well known fact among mopar engine builders. Could've clearanced the block I suppose, but he paid for a drop in assembly...
Might be complaining about stuff that isn't important, but it's the details that count.
Oh, that 400 chevy had sleeves too, and if you know 400 chev's, sleeving them makes the head bolt holes get extremely close to the sleeve's outside bore which usually results in cracks from the bolt hole to the bore.
Fun fun fun.
I too, would not want to run a welded up, ground on crank when I was supposed to be getting new parts. Be different if they told me up front that's what I was getting...

i totaly agree with you mopar,especialy when the correct crank is available.my crank was for 6.200 rod,well we wound up going to a 6.125 to get the ring package down (blower) and get the wrist pin out of the oil ring,well there was the problom,they didnt take in to account the piston coming closser to the counter wieghts.this will be my mission in life to warn people about speedomotive,every body makes mistakes,its all how you take care of you customers after the sell,ill prob get a scat crank and get it all rebalanced.

Torino , I feel your pain man! That is total bs , a 7k shortblock should contain 1st line premium components , not a 'make it work' crankshaft.
I realize 'things happen' , but getting pissed at you for asking them to make it right in writing...well that speaks volumes regarding their intent and integrity.

WOW !! These pricks are still in the business of selling VERY POOR engines parts. They got me way back in about 1979 when I bought an engine kit for a 289 where the sales pitch stated All Crankshafts GUARANTEED not to be ground more then .010" & .010" . Well, of course mine came .020" & .040" but I got .010" bearings in the kit ! So, of couse that was the first & last time I got anything from them. But, I really thought that well maybe it was just a mistake at that time, that over the years they would have gotten thier $hit together, it seems that I guessed wrong.
P.S. I called to complain and get another crank , but they wanted to send me other bearings, I asked about the guarantee? And they said "yeah that they were making it right with different bearings ! So I blew a fuse over the phone and they hung up on me...that was that !

It's awesome how they try to convince you that what they sent you will work just fine despite the fact that their advertising states something entirely different from what you are getting. I know they have it in them to build quality motors, all you have to do is look at some of the engine competitions they've entered. But I'm starting to wonder if they're paying for their "quality", magazine worthy motors with money they've stolen from their customers by sending them garbage and then not making things right. Hey whatever sells motors right? They need to have the Better business bureau called on their sorry behinds.

To be fair - a Windsor thrust bearing is WIDER than a Cleveland so, unless you use bearing spacers which have Windsor thrust surfaces, you MUST add metal to at least ONE crank thrust surface to get it narrow enough for the Cleveland thrust bearing.

Is there another propper way to ADD metal to the thrust surfaces of a crankshaft... ?
IF it is done correctly, there is nothing wrong with welding a crankshaft.

they ground down a 3.00 main to a 2.75 main,they added to the thrust journal,thay turned the counter weights down to clear a shorter rod,after i had to beg them to.they never told me they were going to take a windsor crank and hack it up to fit the cleavland main block.what about the nitrating on the crank.i bought from them a 1-1/2 yrs ago.just puttin the word out.

I don't know about anything which happened to you in the past AND I was only talking about the thrust surfaces here. If you knew the crank was originally a 3.000" main journal crankshaft then what is there to tell you...? It HAD to be a "Windsor" or "M" crank to begin life and either of those engines have cranks with thrust surfaces farther apart than Cleveland thrust surfaces.

Unless it is a specially made billet, there is NO crankshaft with a Cleveland thrust width which also has a 3.000" main journal to start; if it is a 3.000" main journal to start with, it ISN'T a crank with Cleveland thrust width and that is a simple fact so, there is NO WAY to get that crankshaft to a Cleveland thrust width without adding metal. If it begins life with a 3.000" main journal it also already has a wider thrust.
There is only so many ways to say this and it's automaticly understood to any professional Ford engine builder familiar with using a Cleveland size main in a Windsor block.

There ARE other cranks with Cleveland diameter main journals which have a Windsor thrust width; which is WIDER.

Any other troubles you might have had is a shame however, thrust surface welding to get it sized right - is normal, anywhere you go.

I think he was trying to say that they gave him the impression he was getting a crankshaft that was made specifically for his block, not one that was modified to fit his block. Immaterial whether or not that is an acceptable way to make a crank work if you were not made aware that the modified crank was what you were going to get in the mail. Not trying to start a crap tossing contest, just stating things as I see them.

welding is ok for a repair, not on a new crank, just as sleeve is but not on a new block. i pay top dollor i want a premium part. they could have several 2nd W cranks .010 cranks (see lots of them at discount) . just a guess

IF you didn't know that was a 3.000" main journal crankshaft to begin with, then that is a completely different, (and shady), scenario.
