Yeah, not to mention that they're not going to make all those 3.7L blocks just for 3 years of models. The 3.5 was around for a LONG time. The 3.7L is going to be around for AT LEAST 7 years. They'll make improvements to the heads, cams, timing, intake, exhaust, etc but the block will stay the same (unless a big flaw is found that needs to be corrected like GM did with the LS1). The 3.8L will be sold exclusively to the premium cars only for a while and again, those will just keep getting tweaked by Nissan, rather than boared out.
