Help me finish designing my 440 build. 1973 Scamp

I am nailing down the build for my 73 scamp. The 440 block is stock 1973 casting and is being bored and honed +.030. It will be decked to level as needed, line bored as well.

The plan so far is as follows. I am still debating some items and welcome any comments both positive and cautionary (negative).

440source.com stroker kit 512 ci with the ultralite camshaft

4.350 (.030 over)
pistons -17cc dish Forged platinum series 440 source platinum rods
Compression height 1.480"
Distance below deck -.015"
440 source stealth heads 80 cc chamber for about 10.4 CR --unsure about additional porting
Comp cams pro magnum hyd lifters


Items up for debate ( Well I am open to all advice)

Comp cams Xtreme energy Hi-Lift .564” cam 251* at .050 intake 257* at .050 exh. 110* LSA
Torker 2 intake which I already have but will switch if inappropriate
3200 stall converter (recommended by 440 source for this cam )
3.91 sure grip are the best gears I could get for my 8 ¾ 741 case
Headers TTI 400-200
Carburetor – I have not a clue just yet
Ignition- no clue yet
Shifter no clue
Transmission upgrades (727) not sure


Our plan is to build this car for the street and strip. Hoping for 550 hp+. Would possibly do nitrous or supercharger down the line if the need for speed calls. I will be ordering the Stroker kit this week or so.

I am open to hear what opinions are out there. I also look forward to your wisdom.
