You're really asking if you should do a small block Mopar, 318 - 360, like what EM did with a 5.3 LS? No. The GM LS platforms are the better engineered than a LA engine and can take that abuse, for a while, not forever. The 3G Hemi is great, but limited aftermarket and more expensive to do that to. But if you want to do that to your Mopar car, try and find a cheap Hemi, not a LA engine.
And don't apologize. As a car guy, you should appreciate quality and great engineering, regardless who makes it. Unless its Ford, then its always crap.
