The 6.5 GM engine supercharged, note 18:1 Compression ratio, so dont think you can just slap one on and away you go. 300HP seems to be a safe level which puts it in the realms of the duramax. Here in Australia Duramax trucks are still expensive, but us off roaders are using the 6.5 in Cruisers and Patrols even in some fords.
i have two hammerheads supercharged in my boat 300hp
