Mine is the low compression 3.5L model, so can the compression be safely increased for example by changing some parts, or would an intake manifold and carburator swap to an Edelbrock do the trick? Or perhaps something else?

Anyone? Anyone?

The thought of a low maintenance, easy to service, adequately powerful 5.0 sounds really nice. My experience with 5.0 fords was painless.

I would stick with factory carbs unless they are majorly worn out, in which case they should be rebuilt not swapped out, but probably a swap to ten bolt heads and a 3.9 or aftermarket cam would be the simplest mods. I am currently running a 3.9 with CD175 carbs as a replacement for the old 3.5LC but am building a 4.6 replacement, also to be twin carbed, might be SUs yet though.

I'm currently moving forward with a 4.2 swap into my 110. As Paul K said, if I was in a 90, I think I'd go with a 3.9 EFI top. But I have to imagine that going from a 3.5 to a 4.2 I will be able to see a difference. (Am I wrong?)

I don't need to hot-rod, I just don't want to be on the evening news for creating a traffic jam on the way over the mountains.

I love the 4.6 in my 2004 Disco, it has been trouble free. But I've heard almost nothing but trouble from any 4.6 blocks from earlier production. The 4.6 we had in the 2003 Disco literally exploded and left aluminum block shrapnel all over the road. I know of three other 4.6 owners who have had to rebuild or buy all new engines. And then there are all the stories from other places on the nets.

Anyway. I hope to cruise at 60 on my Spanish box. (Already can get there with ease, but cruise at 55.) And I hope to be able to hold 55 on the mountain without feeling like I should pull over and change the oil at the summit. As it is, I slow to 40-45 on the mountain pass that I go over 5-10 times a year.

If this does not work.... I'll have to go to a GM engine that will do what I need.
