Mopar 408 stroker crank cast
Yes. It's cast steel. And bent.
...not in the market for one anyway..
Yeah heat it up and bend it back..
The seller is correct. It can be straightened.
I know and I would do with it.. tie it to a long piece of rope and use it to keep my boat in one place on the river...
Chuck it up between two centers, a dial indicator and a little heat in the right spots...VIOLA!!.... straight shaft!! Some guys are really good at it. Might have to go .010 under to clean up??? I had a close friend who used to weld up the rod throws to make his own stroker cranks. He drove a funny car and was FAST!!!
$40 seems awfully cheap.
I don't know seems about the going price...
You know, I've seen that done! probably 30 yrs ago... I was horrified when I saw him wail on it with a huge copper drift and a sledge hammer. And just as you said, they turned it down to get the rest out of it. The machine shop owner said, 'yeah, people aren't used to seeing that..' , ' major crank Mfg's do it all the time'
My friend was a certified welder and a machinist to boot. So he would weld up the cranks then machine them himself. He built funny car frames at 40k a pop. He was/ is a smart dude and made a ton of money.
It sure does !! Makes you wonder.... maybe there's a tap snapped off in the flange too. Probably never sell it at $40, but would for $125
If I was in the market for one I'd buy it in a heartbeat.
that's been bangin around in my head, since I saw it... I know a real good crank guy..
Wonder how "slightly bent" it is?
Forgot to mention that the 40K was back in the 80s when he was building the funny car frames. The price has more than likely gone up^^^^^^
It's over on your end of the country too. I would think a bit of straightening, may be a little turning and a balance and it would be perfect.
I know, I know... I should just pull the trigger on this deal... a tank of gas, and I'll be crank happy
I'd be all over that like a cheap suit if I was closer.
Get on it, doggonit.
Or a happy crank wanker!!!
I don't know.... by the time you buy the special 408 pistons, machine your block, either modify existing 360 rods or buy aftermarket ones, balance it all and spend a bunch of cash on the rest of the engine why would you put an unknown bent and then straightened cast crank in it. The cast 408 cranks are known to break at the front throw, ask me how I know. Honestly, by time you buy it, straighten it and turn it why wouldn't you just buy a forged one new and not worry about it? IMO it is a boat anchor, and not a very good one as it is too light.
Well I attempted to make contact with this guy... for $40, it can stand in the corner until I can get around to getting it corrected. No answer yet, I'll keep you posted.
Could you just torque it up in a block for a month? Maybe bias a bearing a little with some shim stock? Beating on a cast crank sounds detrimental to its health as castings are brittle. I got a 360 crank turned down to 340 main and the flange broke a chunk when Fedex dropped it. I got the money and the crank back. Still got it. I dont understand the fear of a cast stroker crank. All you need is 4" stroke pistons and a balance. No special rods or bearings needed on a cast stroker. Build it so it doesnt need 6000 RPM.
