Been on the fence a little while deciding if I want to supercharge my old SBC 350 or upgrade into the LS platform. I'm setup for cruiser/enjoyment, no racing, but like "more power" (insert grunting). I just spied an 02 LQ4 with less than 60K miles. I've read a little about them and sounds like they make a good platform to easily reach 400-450HP with cam, headers, tune, heads, etc. Have any of you done this? What about injectors; can stock be used and up to what point? How are the 317 head castings, or is it just better to go aftermarket? I'm figuring the LS platform would have more "driveability" when a comparable SBC with same HP numbers.
