Diff between auto and manual motors?

[FSTRDNU]

whats the differences between a 1g auto engine, and a 1g manual motor?
i know the manual has a 14b, and auto has 13b, but are the cams, or head, or injectors any different?

Injectors for sure are different, 390s versus 450s and I am pretty sure on the cams they are different but someone else will confirm for sure

You leanr something new everyday, I thought the autos had 450s as well

the 1g autos came w/: shitty cams, 390cc inj and a 13g turbo. all of this added together makes them poo(not really but you know)

Add to that different code in the ECU for the 390s, higher base fuel pressure than MT turbo, and a smaller exhaust manifold to match the 13g.
