For about the same money, you can build a 3.3SS engine. Use the LN Engineering 100mm slip fit cylinders, Mahle pistons at about 10.5 -11:1, ported heads with twin plug ignition. Using 964 cams will wake it up some also without being too "rump, rump" ! Electromotive makes some nice direct fire ignition systems for reasonable money. It will be torquey and still make good top end power.
