From the part number, it's a 4.5" stroke casted crank.
Also it's designed for 6.7" rods.

Mr pope, in all actuality, a crank doesn't care what length rods you put on it. And you ARE reading the part # correctly. They list for about $299 plus shipping. fastford, correct its a cast steel piece.

Nope, you're quite correct, that's exactly where I got my info too. :) The point I was trying to make was that a crank doesn't determine (exactly) the length rod that you use, the compression height of the piston determines the rod length.....in combination WITH the stroke. Still, its a good piece at a fair price. And that block is a keeper too for anyone that's within reasonable distance from him.

OK, maybe I haven't had enough coffee yet this morning ;) BUT, why would you have to add Mallory if its an internally balanced DESIGNED crank?
Rob
To correct the balance for the "bob weight" (piston/rod ..... etc ....) :rolleyes: :D

Then they must be expecting you to use a piston/rod combo that weighs like 30 LBS or something! Either that or they are just covering their collective (Scat) rears.

On the one I did 7 years ago with a 2366 gram bob weight it needed like 6 slugs of mallory to get the internal balance. Ended up costing more to balance than the crank was worth. These are a decent crank for anything less than 6500 rpm or so. Running mine to 6800/7000 it cracked after 2 years of running. Lots of guys running them successfully tho.

These days if you are wanting to go internal balance you are better off with the scat forged version for around 800 bucks. They generally balance well with little or no mallory.

The cast one will work good and be cheaper if you stay with the exernal balance but not worth paying to have the mallory installed in my opinion.

Int balance

Yes the balancing may require some heavy metal, maybe not - all depends on the the Rod/ Pistons/rings nad rod bolts you end up using - but the crank was designed for internal balance and does not require the external hatchet weight that would be needed with the external balanced crank - hope that helps
