440Source to release a complete aluminum 8 3/4" center section.

......assuming a Chinese clutch suregrip and 489 gear set.
For those that just wanna throw it in.... 3.55s and a 7290 would be most desirable, imo.
Glad it's offered bare, too
The aluminum center I bought a while back has 4.10s and a spool (9"). It surprised me how little weight savings it had over a nodular iron case.
