“Max effort daily driver” 318 build vs “Budget” 400 swap

I'm doing a 318 now and my last car was a 400.. do the 400, the 318 cost will spiral out of control and 400's can make decent power with a cam/intake (depending on what you consider decent power) Personally i love 400's if i had one laying around i wouldn't be messing with the 318 at all

P.S. i had the heads on my 400 milled i think it was .080 (been a LONG time) and it ran great and didn't cost much at the time.
