Title: Speedmaster
Post by: 475fetoploader on August 05, 2020, 10:18:58 AM
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.

You can put me down for two.

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.

Anyone else interested?

Heard back from my Scat rep.  I'd need 5 guys and the cranks would be $1895 each.   They're pretty lenient on the dimensions, so I think we could mix some 4.375" strokes in with some other dimensions.

Put my name in the hat for one forged crank please.  :D

I feel kinda dirty about talking about orders and money in the main forum, so I'm gonna make a post in the vendor's subsection.  Anyone interested can meet me there.

Bumping this thread. Please do check out Brent's post in the vendor section and consider picking up a SCAT 4.375 crank.

If the OP can change from 4.25 to 4.375 then we may only need one more person to make it happen.

Brent - can you clarify the details of the Group Buy? Like E4340, billet/forged, nitrided etc.... Thank you.

BBC rod journal, any stroke from 3.780" to 4.375" (including both of those).  They are 4340 forged and would be nitrided.  Gun drilled, scalloped flywheel flange, etc.
