difference between these 2 engines?

[1972BlueC20]

Am I correct in thinking that these 2 engines are the same except for the 1st one has an intake manifold already installed and comes with a chrome dress up kit? Are there any other differences?

Also, I'm debating on doing the engine swap myself vs having a shop do it for me.....the only part that makes me nervous is the unbolting and un-connecting of the engine and transmission then the reconnecting. I'm pretty confident with everything else.

I'm also a little nervous about the engine hoist since I've never used one.

So as for the unbolting of engine and tranny.....I just unbolt the bellhousing bolts and the engine mounts and the engine will just slide forward and up away from the transmission shaft?

If anyone has any suggestions or tips or can share video links that would really help!!!


Thanks,
