Help spec'ing out a new small block

@boosted Best flowing heads possible…. A camshaft that takes advantage of the heads flow capabilities.

The 5C rule
Cam
Compression
Carb
Converter
Cogs

(6th-Cubes, more optional)
Yeah, and looking at that list with the parts I currently have, here's my bench racing assessment.

Cam - Solid Roller .660 lift, 254/268 duration @ .050 and 108 lobe center. Decent specs, could be bigger but probably perfect for these heads.
12.5:1 CR
977ish billet 4150 from Dominic Thumper
5800 stall (flashed right at 5750 on the chassis dyno) 9" PTC non-lockup converter. Probably too much stall in my opinion but we will know for sure once it goes down the track.
Spooled 4.30's on a 29x10.50 Hoosier Drag Slick with stiff sidewalls.

408ci which is as big as I would go with this block.
Out of the box Trick Flow cnc heads and Track Heat intake (blueprinted on install)
Hedman Hustler 1 7/8 primaries and 3.5" collector running through 3" mandrel bent duals with x-pipe and Dynomax UltraFlow SS welded mufflers.
