Daily driver small block build

This is a question for wilrun318, his 318 and 360's are put together on a budget, producing respectable power and mileage.
Myself if I was doing a swap, it would be a 5.7 Hemi.
while the G3 seems very much "the way forward" the financial part of that swap is monster of a pill to swallow. if you're talking about trying to make something happen for a few grand that's a nonstarter in the G3 arena-- just the peripherals to make the swap are a few grand: mounts, exhaust, oil pan, wiring/pcm and lot of that simply isn't available used or at a economic price point.
