Not trying to jump ship here but what about 4.15 x 4.31 Hemi with stock heads? I see from some of the combos above, those heads flow more than stock Hemi heads so would those engines be compatible in torque numbers? Impressive engine numbers for all posted so far.
My HEMI is 4.36 x 4.5 (540 ci). Strictly a street engine on pump 93. 10.3 compression, MP aluminum heads with bowl work. Mopar “Marine” dual plane intake, 248/254 @ .050 solid roller with .580 net lift.
It made 500. Ft Lb @ 3,000 rpm, 680 ft. Lb @ 4,500 rpm and 677 HP @ 5,800
