Similar ? C280 W202 V6 / C43 W202 V8 / E430 W210 V8 / E55 W210 V8

[97 SL320]

I dug around a bit but ended up not getting much info.

The 98 and up C280 came with a new generation V6 and the AMG version was a C43 V8 based ( near as I can tell ) on the E430 V8. Is the V6 and V8 built from the same family of parts?

Is the E55 V8 based on the E430 engine? Was the E55 motor used anywhere else? ( GL? )

If the C280 V6 is similar to the E55, I can picture a E55 motor in a C280 body. . . .

Thanks
