convert D-Jet 450 K-Jet?

[WANT '71 280SEL]

I have access to a whole K-Jet 450 for little to nothing. My 109 has D-Jet. Wouldn't I just need to swap over the intake, fuel pump, and K-Jet components?

I realize the later K-Jet 450's had less power, but is it because of the fuel injection? I'd assume it has more to do with the cams, etc. used later for smog purposes. Is this a conversion you would suggest?

I'm not a big fan of D-Jet as it seems it's rare for a 40 year old system to work correctly. Given the trigger points, and computers prone to fail, I'm not big fan of the system. What do you think?

Best Regards,

David
