Chris, yeah, the 4800 stall should work great, as long as its a good unit & you don't have too much slippage, & i'm thinking Rumble might be right about a single plane intake, either the Victor or M1.
About the gears, i'de think the 4.10s with a 28" tire, or 4.30s with a 29.5", or 31s with the 4.56s, but can you stuff a 31" under the car, don't know how well your budget is, but sence you have the 29.5", a 4.30 should do it, i trapped around 6300 with 4.10s & a 28" tire, this was at 123+ mph, there are calculators that will show you what the trap RPMs will be with tire/gear/mph, you need to find out what RPM you feel safe with or where the engines makeing its power, its okto trap around 500 rpms more then your shift points, i shifted at 5800, trapped at 6300, so just say you shift at 6300, you can trap at 67-6800, maybe someone will have some sights they can post, i know one is Wallace racing.
Moper does have a VG point about the heads, the eddys are great on a 440 in stock form, but those cubes will swallow them up & they will hit a wall in stock trim, so i'd test them out the way they are, then after a while, yank them off, have them ported & mill them some to get closer to 11.1 compression, or if you can sell them for a good price, it will at least put you 1/2 way to a set of way better heads, the Indy EZs are a nice head, stock they flow 300, if you raise the window on the ports to Max wedge (i've been told its easy), they will go 330, they were casted so this could be done. Indy had a nice kit about 3yrs. ago on there EZs, you got the heads/head bolts & i think pushrods, maybe even head gaskets for like 1899.00, not a bad deal seeing how well those heads flow, they will support alot of HP.
