C4 vs c6 in 4.9l

hey so I need to do an engine swap on the 4.9l engine. It is currently mated to a C6 transmission. I found an engine that was mated to a c4, will this work with my c6 trans? Or is the bolt pattern different?

The trans bolt pattern on these blocks never changed so you're good.

If you're doing a V8 swap like what you posted somewhere else, the flexplate for the six will not work. It's neutral balanced, the V8's are externally balanced and have a counterweight on the flexplate

What about is I found a 4.9 engine that had an e4od transmission? Would the bolt pattern be different on that?
