Critique/suggestions on 273 engine build

If cost is a concern, sell the 273, and buy a 360. Your piston choice alone will cost more that a running 360.Plus milling heads,buying cam......a STOCK 360 with a 4 barrel and headers will be way ahead, and much cheaper. If you want to use the 273, just stick it in, and live with it. You will never be happy with it's power, unless you spend BIG bucks. I understand your sentiments about using the 273, and respect that, but you did say you want more power, right?
