61.2 cubic inches per liter, should be around a 390” , 475, hp was in old days would win every Friday night ! I think they only put the 6.4 hemi in 2022 only.
They had the 6.4 a few years back and had a few issues. Probably resolved that by now.
Yep right at 390 but still small to me. No doubt something in the 450" range could make at or over 600hp pretty easy.
