I went the SBC route because there's no way I could make the power I wanted to make using an AMC, and make it affordable/reliable.
There are other reasons people use a SBC..........
With that said though, I'm all for staying with a good 360-401 in a situation like this.

Lazy is a very harsh term don't you think?

I did the research and decided against it for a number of reasons.
Lazy was not one of them.

I do agree with you on the old fords having chevy engines, that ain't rite!

Alright guys I have decided to go with the AMC 360. I have found one out of a 76. It's is almost complete just needs a distributer, carb, and manifold. What are the challenges ahead? I have a lot of new parts on my 304 like a distributer and a FlowKooler water pump. Will any of the parts I need exchange from the 304 to the 360? Any suggestions on a reasonably priced carb? Some pics below.

A) keep your 304 motor mounts (you can't use the original 360 mounts)
B) you need a 360 flywheel (difference in balance)

Everything else is interchangeable. The engines are the exact same size in outer diameters, the difference is all on the inside. It's a really easy swap.

Recommended timing of 10 degrees on a stock 360.

Also, because of oiling deficiencies, you will find that most people recommend starting your build around a brand new oil pump.

I'd put in all new gaskets & seals too while your at it. Head gaskets, intake gasket, oil pan,rear main..etc. Felpro or Mr. Gasket kits pretty much cover it all.

X2...timing cover, water pump...you can get the entire gasket kit for about $80 and the intake gasket is metal and costs about $30

That's simply not true. Even the lowly LM1 in its worst incarnation makes a bit more power than a '78 304. And its easier/cheaper to get to say the 250HP level than it is the 304.

If you aren't averse to spending 1.5-2x the money for the same power level you can get with the SBC platform, go with an AMC motor. There's really no "better" or "worse", but SBC's are cheaper to build - all day long.

Yeah I'm interested! Not sure how much an intake would cost to ship though. Is it a 2 barrel? That's what I am looking for. The 360 I am going to buy comes with a 4 barrel intake, but I have read that a 2 barrel will put out more torque. PM me and we can talk a little more about it.

Intakes are interchangeable between the 304 & 360, but I don't know if the factory intakes are the exact same.
