Which v8 engine should i have

[dio99]

I have just bought a defender 90 and have the option of a 3.5L engine or a 3.9L engine, which one would be the better option.
If you chose the 3.9L option, I then have a chose of 3.9 efi and 3.9 carb?

Depends on your skillz. The 3.9 is torquier and is what I'd go for. If you are a whiz with 30 year old fuel injection systems, then go EFi. Otherwise go carb!

Thanks for your help, I personally have very little knowledge comes to engines. The person I have bought the defender 90 from is the mechanic that will be fitting the engine and he has offered me either one, I'm also having an automatic gearbox fitted which he has.

Go the injected 3.9 - the 4CUIX system is simple ans easy to maintain.

if the original vehicle was carb, there's quite a bit of work to go injection. Not as simply as just swapping the engine. I'd find out how much it would cost first.
