380 crate cam and stall converter
Appears you have plenty to work with.(Information provided above)
I am running a 408 Magnum with a 2800-3000 stall, also with a 904 & a 3:91. timing @ 24 with 34 total. It has not been on a dyno or at the track.
DUI ign. Seems fine. Just need to put it on the dyno.
