No reason why not. Sounds like a fun project!

Im just not sure how big of a project. I was wondering about electrical and changes I would have to make...has it been done...and is it very difficult...I know that the engine will fit. Im just wondering if it is just too big of a job....what are some of the definate issues that are seen?

Wiring will be the biggest hassle that I can foresee. Grab copies of the wiring diagrams for both and look for the differences. The SE motor has an electro-mechanical device that pushes the throttle on a little bit when required - I think such as when the car is in gear and when the A/C goes on. Also, I think there is some temperature sensors that adjust the FI when cold. And lastly, you will need to run wires to the fuel pump at the back. The fuel tank may be a little different but that should be ok. Not sure about fuel lines, but as the carbie cars still had a return line you should be ok.

So unless someone hops on with specific experience, you had best pore over some wiring diagrams. I wouldn't be too scared of it though, wiring is reasonably logical. But it may be awkward trying to do the wiring and make it look pretty.
Good luck, Drew

I did this once to a 220S convert to SE,
Was not worth the trouble.

The wiring, relays , I just hard wired toggle switches, for cold start.fuel pump in the rear. etc. Transmission type?

I do have a real good 280S motor/trans which is a logical install,

do whatever you wish.

tranny also included in the purchase thanks for the input I do think it is worth the trouble as the car is one I plan on keeping for 30 years...so any help is appreciated. the 220 is a much different car...i know the the engine is carburated. so I dont think there is going to be much of a difference. I have decided on doing it so only helpful advice please....I will take a look at the wiring harness for both. maybe someone has a site to refer to. also. my father is an amazing mechanic. just want to know if there are any huge issues and it sounds like...not many..can anyone else give some advice...i will post pics so as you can see car is in excellent shape and worth it. thanks guys and gals

by the way bostosh......that car is beautiful
