6.2 can be done to any gen 2+3 engine (i have 2 of them ).
95% of the work is in the head,crank,pistons+rods are all standard,but rods+pistons are matched for balance.Ti valves,springs,billet inlet+exhaust cams.no porting though suprisingly.makes around 215-220 depending on dyno,but have much better mid range i find.
then the variable airbox inlets are modified,and also have a heavier weight (assume to drop them back faster,but not 100% sure of the reasoning?).
?12k from Alpha!!!
if your interested i'm splitting my spare alpha engine+Nova LITA gearbox,the head is basically a bolt on part..
