Street strip car, 6.4 hemi.
Reason power vs drivability will be better.

I've made more HP and torque on all of my pump gas low deck 400 block stroker motors that I did with similar C.I. gen two 426 street hemiroid motors with similar carbs I had to learned to trust the results(track and engine dyno tests) of these build and I now concentrate on getting the best heads I can get to start with and go from there BTW, I like and use 4.250 and 4.300 stroke cranks with 2.200 rod journals on these builds with the longest BB Chevy type rods I can get away with, 6.700 or 6.800 with .990 pins and a custom piston order for that specific build My first 511 C.I. 400 block stroker made 612 HP at 5500 RPM and 644 Ft lbs at 4500 RPM with a mild set of 906 heads with big valves(2.14 and 1.81 ex.) and a low deck sixpak setup That same motor with a .050 longer stroke crank, went from 4.25 to 4.300 to increase the comp. ratio from 9.25 to 1 to 10.3 to 1, ended making 775 HP at 7500 RPM with a ported set of 440-1 with 2.250 intakes on Oregon pump swill at 4300 ft elevation on a calibrated DTS engine dyno with a stock 400-3 intake and 1050 Holley Dominator carb

I voted 6.4 mainly for great drivability with the right o.d. trans and the right rear gear.If you want killer instant insane low speed torque , top that 6.4 with a twin screw blower and hang on. It will need forged pistons and good rods.

The 6.4 has more potential apples to apples period. Plus they are very easy to crack 600hp on pump puke. The difference is they also do it with STOCK valvetrain and juice lifters 0 maintenance. No $1000 lifters, $1000 rockers or $2-3K to get GOOD heads needed. THAT is why I made the change.
Mopar to the bone!!!

Prefer the K.I.S.S. principle myself. Low deck stroker, plenty of options for parts.

Either the 400 or 440 with a 4.25 crank. I'd probably do the 440 myself...... The header choice situation is slightly better along with main bearing choices.

Prefer the K.I.S.S. principle myself. Low deck stroker, plenty of options for parts. When I built my Duster I literally lost sleep over this very subject, which engine combination to go with. I planned on a Gen3 Hemi but all the prices were adding up too fast, then I decided on a stroked small block but I ran across a super stock drag racer selling a brand new 500" low deck(400)stroker kit and I am glad I went that route since I wanted to run a 727, 3.23 gears, and a fairly tight converter along 10.5 to 1 pump gas compression and a mild solid cam. Header fitment is a big issue with the big block A-bodies and working on the engine and trans and starter can be frustrating but other than that it is such an awesome combo for the street. I cruise my Duster every sunny day, never runs hot even on a 95 degree day, gets decent gas mileage and it will literally do a smokey burnout at 50 mph! Very fun combo.
