SIKFISH 6.4 Hemi Build

Yea the 6.1 is what I originally planned since they are easier and cheaper to come by but i'd came up with the idea of just installing a cam in the 6.4 and tune it myself. I've tuned several other vehicles around town and the hemi would help to further my knowledge of tuning. Are you gonna do any engine mods to it or just drop a crate engine
