I've never looked back from leaving the LA platform. It depends on what your end goal is for the car. My end goal didn't involve leaky valve covers, oil pan seals or fiddling with carburetors. I've been nothing but happy with my Hemi swap, I'll need some more power though. A whipple on a stockish 5.7L will easy net me 500+whp., my last road trip netted 20-21mpg on the highway with where I'm at now.
