Re: I-6 Vs. V-6
v6 are better at achieving a lower center point of gravity. Hence why the new z350 has a v6 instead of an inline 6 like the rb26dett and more likely the new skyline will use a v6 type engine instead of a inline. I've seen where some Japanese tuners have used the VQ in a r34 to lower the center point even lower then you could of with the rb26dett. I know this doesn't really pertain to the tq debate but just another note to add into the debate. I like my L28 in my Z and inline engines better just being alil more easier to work on instead dealing with two heads to deal with. It may be a taller engine but ease of working with it is a big deal with me. Just one reason why I would never buy a z350 or a sube or anyother v type engine.

I6 engines are superior (IMO) because they have more main bearings than a v6. This stabilizes the crankshaft more, and allows for more tq production than a V design, with less stress on the bearings and the crank.
btw, 350z = z33, not z350
If you make your ports too big they won't become efficient until you are out of revs. The key is to have the right amount of flow. If you make ports that flow a lot more than your engine has a chance of digesting you're only losing power.

At one point when BMW were using a straight 4 cyl engine in their Formula 1 cars, they tilted it 90 degrees to push the weight all the way to the ground so it was angled like a boxer engine.
