hmmm sounds like my dream as i have to use the a-12 block for rally

first is to put 1400 internals in to get that displacement up, and all the good pistons and cam, it would have the a-14 gx head(oval port naturally) but may require bigger valves, custom injection, nice equal lenght extractors, 2inch zaust, thermo fan, elec dizzy, elec fuel pump, possibly elec water pump, all sitting in front of a close ratio 5-speed and lsd h165 ute diff

hmmm, i need to go change now

p.s. no turbo allowed for rally, but you didn't say naturally aspirated so if not for rally she'd have a big huffa on it too

p.p.s. the motor would be hand built by the chick in your avatar, and id be sitting by watching the WHOLE time
