- Wow what a price. Hmmmm. I wonder how much shaving the block would need for this. If I bought this and sent it with my block to Mazworx, I wonder how much it would be for them to spec my block for this crank. Just when I was trying to keep things simple.

That is a true statement. Just because it is forged doesn't mean it is stronger than billet.

It's obvious they mis-labeled this crank, it's not a billet crank. Forged? Yes.

Take a look at the counterweights, they are not machined. The leading edges are rough. The machining process would leave a shiny finish like the journals.

Since they are in LA, I could stop by and take some pictures.

I read the pro-billet argument in the article Miko linked in the other thread. I'm convinced those arguing for billet don't understand how the forging process works and what it actually does to the grain of the metal. Nor do they understand how machining a forged billet slug ruins the strength gained from the initial forging.

But I'm not a metallurgist, so I'm not going to pretend to make an argument for strength one way or the other anymore. Obviously both forged and billet cranks have been shown to be completely adequate for 99.999% of engine builder's needs. The point is purely academic now.

^This would be great. The more help, the better.

Or go and take some measurment rather then pictures. Let's see how tight of tolerences this was machined to..and weigh it too

Then there is Funny business afoot because the Mawork crank is listed as billet with the same features.

Mazworx 91mm Crank as quoted ( SR 91mm 4340 billet stroker crank )








Mazworx 92mm 4340 billet crank weight




Cheap Price EBAY 92mm Billet Crank

I think the crank is billet just like the Mazwork crank 100%.


The machining process of the crank will determine if the machines surface of the leading edge would be polished or not. It all has to do with the cutting tool that they use to chip away at it with which detirmines the surface grit

People in NZ have been using this for a while now with no failures up to date known.
Might even be the same supplier
