440 or built 360 71 demon

I have often thought of going big block in my dart. But then I start looking at cost not so much for the engine but everything to make it fit. 800.00 headers, 200.00 mounts, 350.00 driveshaft, radiator,and so on. By the time I build a big block and buy all the parts to make it work I can build a strong stroker small block that fits in my car much better and weights less.
Damn I have been out of the game to long. Lol when I built my 73 dart I think the TTI headers cost me $690 shipped and the conversion engine mounts was around $140. I was going from a 904 to a 727 so I had to have a drive shaft anyway. I just had a 7290 ujoint size drive shaft from a B-body shortened for the dart. Also a aluminum headed 440 doesn't weigh much more than a small block. But if you think the small block fits your needs better. Then that's cool. Got any pics of your car? I used to own a 1973 dart sport that I put a 360 in.
I hope soon to start working on my 72 dart. I want to install a. 360 magnum motor and trans out of a 98 dodge truck and even run it with the factory fuel injection
