My plan is to definitely use fuel injection. Probably just a LS2 intake for starters. But I am open to change it to optimize my powerband, for sure.
No horsepower or redline goals, as long as they're high enough to get me the torque I want.
Inch for inch, I think my undersquare six liter motor will be better than the stock 6.0L out of a truck, because the longer stroke should help power come on earlier (juxtaposed with the 3.6 crank), and I will have a higher redline. So, compared to the stock six liter LS, I should see my torque earlier, AND make power higher into the rpm range... with the proper cam, of course.
Even using a stock six liter cam and stock six liter tune, the 4" crank should give a noticeably broader and flatter powerband just because the torque should be showing up earlier, all other things being equal.
Note, I will be using heads ported to flow AT LEAST as well as stock six liter heads. So in a 6.0 vs 6.0 shootout, even if head flow, cam, intake, injectors, and tune are all the same, the only difference being undersquare vs oversquare... My undersquare motor SHOULD have a better (being broader and flatter) powerband with the same top end. If my heads flow the same, despite the smaller valves, and if the 4" crank doesn't lower the redline, then I will lose nothing up top compared to the stock (oversquare) engine. Yet I should gain a noticeable improvement down low.
