and to go one step further....

the reason i said dont get a motor from a commodore is that to make it fit an hq to wb you will have to change..which meens buying which meens more money than first thought...
alternator bracket
crank pulley
water pump coz commodore is a long shaft
sump and pick up
engine mount to block plates coz if you dont do thes the motor sits in the wrong position.
also commodore gearbox as in autos is left hand side shifter only...
