but is true the dampener is diff between 440 and 400 cast cranks ?
There are pictures of the dampeners in question in the tech archive section. Look pretty different to me.
aren't those pics making comparision between forged and cast crank dampeners ?... I'm talking about being both cast cranks.
There's another picture of a 440 balancer in there. Looks different from the cast 400 balancers that I have.

width is the same, but the bottom of the bores are closer to the crank centerline on a B compared to an RB

I've done forged that didnt need the diameter reduced but did need a few spots on the webbing clearanced... But with a cast one, no way. I believe it's about .200" to take off. You've been told they are different and 440source had an entire different crank made for the B wedge... so those two seem to hint that it's the truth. If you feel this can't be so, get both cranks and measure them. B and RB look the same. The are NOT the same, but they look it. In regard to Andy's thoughts... you'll save the money on the crank to spend it on pistons and light rods? I don't see the logic there but as he adds, your situation and wallet may be different than mine.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

I know RB and B cranks are diff, but room inside block does look exactly the same so I can't see a reason to reduce diameter on counterweights to fit an RB crank on a B block. I know maybe could need some angle grinder on counterweights to get some clearence, but Cut the counterweights because diameter ? seems no logic. Then we can talk about experiences checking here ( yes I asked the same about cast cranks there... on those days I didn't have any crank, I was just asking ): http://www.dodgecharger.com/forum/index.php/topic,22274.0.htmlnote NOTHING IS BEING TOLD ABOUT DIAMETER! sorry the multiple questions and everything, but more info available, less doubts to everyone and wider options to build anything.

My house looks exactly like my brothers. But his is a colonial and mine's a ranch. The deck heights on teh R vs RB are shorter.. That's the distance from the crank centerline to the top of the block on the head surface. So it's the depth (like ANDYF said) that's the issue. You dont have to trust me of any other poster except ANDYF. He has a bunch of very good published articles and I'm sure forgot more than I know. THEY ARE DIFFERENT. I've never been to the Charger site, but on all sites there's a ton of guys who mean really well but might not know all the little idiosyncrasies of these. And many more who say they do and only read and type a lot. I've only built 3 over the years: one with forged factory crank that did not need to have the counterweights cut; one with the 440source RB crank that we did have to cut .200 off; and then one with the 440Source B crank that had a little taper but otherwise dropped in place. If it was available back then I'd have used the 440Source B crank. I'm pretty sure ANDYF has built many more. It's up to you. Try it and see what happens.

yes I have read andyf website and 451 manifesto, but also I can find several info what says based on experience ( like the charger website by Challenger340 ) diameter doesn't need to be touch...
you see ? opposite information, and both are experienced guys.
So, apparently does look only cons on a 451 build with cast crank is the counterweight density for balancing once is cut ? ( no matter if angle grinded for clearence or diameter cutdown for better fit, whatever is the true )
............
then on a "note appart" I'm thinking on 400 rods unless I find locally 440 rods.

It's been a while. I was thinking of building a lowdeck stroker with a cast crank. IIRC GregZ told me it would take lots of Mallory metal to balance it out. There is a thread right now on a cast crank slant on www.slantsix.org in theory it should spin up faster etc. Cast is good to 600HP? More than I will ever need! I am sure there is ways to lighten the cast crank even more? Go light weight on the rods and pistons?

you call that not cutting the crank? 3/8" off every corner with a 4" grinder? Have a good time.

dave - too bad we dont have a talking to the wall smiley...
I've seen a 3/8" angle cut , i've seen mains cut down, but i never saw one drop in. just my personal experience.
