New Forged Stroker Crank

That price would be to rich for me to spend on a 360 build. The thin webbing in the vast majority of 360 blocks makes it tough to shell out that much for a billet crank. This is likely true for most. So, that limits your clientele down to an already small 390 and 401 crowd. Then depending on the flange it would further limit the possible customer base unless it is offered in either flange (fortunately that would be simple enough). I wish the forged was more affordable because that would help make the line more sustainable.

It would take a minimum of 50K to make casting plates and a minimum order of 200 forgings. So by the time you have something ready to grind on it is a ton of money.

Just to toss these numbers around a little,

 50k+ for the plates
200 minimum forging order

Then +$ for the machining costs = $250k total?

Could 200 raw forgings satisfy the minimum order requirement, with or without final machining?

Assuming the raw forgings, without machining, would bring the cost down substantially.

I know it's a long shot,
but if there is a market for the raw forgings,
it may be easier to get 100 people to order finished cranks/kits
+100 people who would want raw forgings while they are available.

Even better would be designing the raw forging to be machinable for similar engine that also doesn't have a new forged crank available to it either that could share the raw forging:

Buick 400/430/455's have the same bore spacing as us, and have an even worse crank selection issue (cast stock, custom billet, or try to adapt Nailhead 401 cranks).
If the raw AMC forging was close enough, there would probably be as many crazy Buick guys lining up for one as crazy AMC guys.





Just wondering.

I could see the Buick and AMC cranks as interchangeable at the forging level
but balancing differences may prevent this.

I seem to remember that Buicks are externally balanced, but do
they share the same counter weight configuration as AMC?

I bet there is a lot more Buick nuts out there than AMC nuts.

Any time you are talking something as complex or labor intensive
as a forging die it's gonna be big bucks.
