give me one REASONABLE REASON to not use a cast crank on to 451 stroker engine IF IS A TOTALLY STREET CAR and maybe just an ocasional WOT on a traffic light with some stupid guy challenging.
NOTICE I'M TALKING ABOUT A TOTALLY STREET CAR... I mean that because 80% of members on all boards thinks only on race/strip cars

If everything is going to be (re)balanced can the std dampener be used rather than the oddball one? Nacho what pistons are you going with
Sure if you have the assembly neutrally balanced. It will take some slugs of mallry metal to do it.

is a VERY future plan, since I'm working now on KB240s piston setup. I want to go step by step, beside the fact I got everything BEFORE get this crank ( FOR FREE BTW )
I would use the same pieces I have now... my actual 400 damper, already counterweights on TC, and rods... well just if I get some 440s dirty cheap will use them, but being will be hard LOCALLY, use my existant 400 rods is actually on plans... yes I know, rod ratio and everything about rods weight, but as stated is STREET and on the other side, pistons will be with longer skirts.
I have been adviced about use just forged crank to make this, but REALLY I'm not thinking on race ( ever ). I get scared at high speeds, but likes to feel the WOT sensation quite often, that's why I KNOW FOR SURE I won't race. I don't consider myself a pilot, and I'm very respectfull with speeds, specially on an American Car.

not to mention a 400 dampener and a 440 dampener are counterweighted differently.
really? didn't know that I thought where the same.
what about TC counterweights ? are they different ? or are they simply the same but positioned different ?
diff flywheel/flexplate ?
the 400 and 440 cast crank have the same balance factor. you can interchange the weighted converters and flywheels with no problem.

but is true the dampener is diff between 440 and 400 cast cranks ?

You can. But, you will spend some cash to have the cast crank counterweights turned down to fit your block in addition to the normal turnign down of the mians, and you wil need to mock up the block because I'd bet they hit the main webbing a little too. Then you have the balancing issues. You need a 440 dampner for the cast crank, plus the torque convertor weight for the 440, plus you'll need mallory anyway because you turned off a couple hundred thou of counterweight metal on the outer edge of it... It sounds like a smart a answer, but just buy the 440Source B wedge 3.75 stroke crank and run that (after it's checked for size and taper). It's a lot less hassle. Then you can run any nuetral (forged crank) balancer and any nuetral convertor, and won't need any mallory.
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.

There are pictures of the dampeners in question in the tech archive section. Look pretty different to me.

ok, if so, then is becoming HARDER with a cast crank to make it work.
where would meet to need to turned down the counterweights ? aren't the 400 and 440 block same room inside on area below cilinders ? the oil pan is the same, gaskets and everything. Block is diff being taller, but thats on top, not on bottom of cilinders. Timming chain is teh same so distance between crank and camshaft is the same, so block should it be basically the same above crank level... or not ?
( yes I know about the 440source stuff )
then, you are saying about the TC weight for the 440, but some of the rest of ppl is telling opposite, being the same than my 400 TC ( already MP unit with weights welded )
then also on diagrams to mount TC counterweights, sheet states 383/400 but doesn't say 440.
Ok I still can't believe we CAN'T get an agreement on some that should it be already stablished.

then... why I would need to turnd down a cast crank and not a forged crank IF both are same stroke, so same size ?
ok, guys maybe is my ignorance but lot of this stuff sounds simply without logic.
