The ripoff gas prices in Canada has everyone rethinking their builds lately. I kept the 383 in my sweptline rather than dump in a 440 like I normally would have and on my Challenger I went with a 528 rather than a 572. Both decisions were strictly based on potential fuel economy. I would have done a 472 for the Challenger but I wanted to lose the 20 lbs from the cylinder walls going out to 4.5 would do.
