meh, forget about the holden V8 and late 5 speed, put a late LT1 reverse water pump engine in it with a 4bbl and Muncie, or just go Big block with Muncie, nice 454 vette style engine with the came setup, set of alloy heads, lowe intake from a vette, set up mounts so hood clearance not an issue, pwr steer and fridge will bolt up, make it look factory...nice, H series Holden with a fatty...
