That's because LSs are a cult. I asked a shop well known for big power LS builds if it would be cheaper building a big block or an LS. The only condition I had was 500lb-ft at 2500rpm. He told me there was no possible way to get a big block to do that without going to all expensive forged parts, and that an LS was the only way to go. He then showed me a build they did recently that almost made that torque, for $17,000. Meanwhile I can buy a 502 from GM for $8500. Only a cult member would come up with something crazy like that. I don't care how good the mileage is, $8500 buys a lot of gas and the 502 will do it on 87.

LSs have their place, but low end torque isn't it.
