Need some advice on choosing an engine

I had the following build many moons ago. It ran 10.70's in good air at 3400 pounds. I weigh over 300 as driver.

30 over 340 block(360 will work fine as well)
4 inch steel crank
Eagle H beam rods or similar
Zero deck flattop pistons
Ported eddie heads( Modern cylinder head has an excellent cnc program, that will make plenty of power) in fact having them do it would make more power than my stage 2 Hensley racing eddies did
727 or 904( i ran 727)
Typical 28 inch dot slick( hoosier Qtp's in my case)
8 inch convertor suited to combo
4.10 gear will work( had 4.30's at times as well)
Good hp carb, likely a 950( i ran a 1025 4150 race demon)
260/266 comp flat tappet with 1.6 crane rockers. Ended up 598/623 lift
Weiand excellerator intake
On several occasions i drove the above combo 70 miles round trip and layed down 10.70's and Eighty's consistently.
Was about 11.7 compression, mixed in some 110 with pump premium

I like the idea of a small block in an A body. Lighter, WAY easier to work on. Gets ultra tight with header fitment with a big block. Just no room, you will get tired quickly of fighting everything
With the 4 inch crank these days, makes it a no brainer
Btw, i just ran the TTI step headers on that motor( 1 5/8 to 1 3/4) i am sure a 1 7/8 tube would have made more power
