best engine to build!!!!!

I have a couple of cars to check out and they are 318's. I thought that I would go with a 4 barrel, good true dual exhaust, curve kit, 3.55's or 3.73's. And possibly a mild cam and just enjoy the ride.
It don't take much look at 80/90 5.0l they were the **** with a whopping 225 hp net which is probably 250-270 hp gross.
