Long rod motors?

What the hell are you talking about?? The crank doesn't get changed at all, just the rods and pistons.

Marco "claims" that in theory, based on the geometry, the rod ratio difference is worth about maybe 200-400 rpm more, but in practice it's worth alot more.

My main reason for going with the long rod version is not because it was the most expensive (althought some might think differently

), but because I wanted the "best of both worlds" so to speak. I wanted the longer stroke of the 2.4L for my heavy car, but I also wanted the ability to turn higher rpms with less chance of scuffing the pistons/cylinder walls that can happen on a high rev'ed 2.4L

with regard to a dry sump, once you start using one the crank doesn't have to plow through all the oil in pan since the scavenger pumps keep the oil level in the shallow (custom) pan very low. i would call that less parasitic drag.

i never mentioned anything about changing the crank.

Next time mention what you are talking about. You didn't mention anything about talking about the dry sump system. You can't expect us to read your mind.

The crank doesn't plow through oil in a normal wet sump either. The oil level is well below where the crank spins.
