Sheeze, what a loaded question stiffy.
And Bernie is correct, you have little choice given you can't register with the engine the car deserves. That's if you want the freedom to drive unrestricted.
My choice, if I were to make it, and not colored by allegiance in any way....I would go chev.
After rego I'd do an Aussie Mike ..... hide the coil packs to expose the rocker covers and put on an aftermarket intake. Either a 4 barrel like Mikes or an 8 pack. It will then look the part.
The new fords will never look the part because of the wide rocker covers.
The standard ECM will drive it so if you were to have problems with the law just swop back to the factory intake.
Very easy and relatively inexpensive to do with the chev whilst having the ability to make unreal power.
Now......watch me get ripped to shreds.
