Ok so Jegs advertises Speedmaster 4.375 forged cranks, drop shipped starting 8-14-20. Has anyone heard if they’re any good, and really available?

I know of literally zero Speedmaster products that I would trust, especially ones that have to rotate at thousands of revolutions per minute while trying to handle massive forces acting upon it.

+1 on what Brent said on Speedmaster quality (or lack thereof).  Also, it wouldn't surprise me one bit if that date came and went Summit's site, and a couple days after that date it was pushed out by another month.  That same thing happened with my PAC valve springs that I tried to order through Summit.  Pushed out a month four times before I finally cancelled the Summit order and got them from a different distributor.

     I wish the American public would stop with this determination, or maybe it's a syndrome, to purchase the CHEAPEST-SHYT-POSSIBLE!             :o

Anyway we can do a group order for 4.375 cranks through Callies or another quality American manufacturer?

I can do quantity order of custom Scat forged cranks in a 4.375" stroke, 2.200" rod journal.  Would probably take a quantity of 5-10 to get the price "do-able" and even then they'd be somewhere around the $1800-1900 range.

I have too many projects like normal. Ok 428 block Edelbrock heads basically out of the box. It’s going into a 4x4 pickup. I have a mental block about cast cranks. What kind of limits does a 4.250 crank have, rpm/h.p. Let’s assume Molnar rod, diamond piston. Flat tappet cam.

You'd have no problem with a cast Scat crank in that application, plus a couple hundred horsepower.

And you can put me down for 1.

I am curious, as these are custom forging, would they all have to be the same, or could we ask for variances.

For instance, a 2.1 rod journal and longer stroke? I asked about this I. Another thread, still not sure it’s worth messing with but figured I would ask anyway.

I am assuming that these are all cut on CNC machines so what would it matter to change it up a bit..

Probably so.  If I can get a couple more guys interested, I'll see what my Scat rep says.
