According to GM specs there is a 150 lb difference between a Gen VI 454 block and the ZL-1 block. That's pretty significant. I'm pretty sure it puts me within 100 lbs of an LSX and should be comparable to a small block with aluminum heads. EVERYTHING under the hood is aluminum as well. I guess I should look into the dry sump option a little more. I already have plans for a road race pan, windage tray, and scraper. Keep in mind that I also have a 3qt accumulator. I wasn't having oil pump pickup problems with my street strip pan and accumulator that I know of..... I've got to cut myself off somewhere.
