What problems will I run into putting a 99 3.5L out of a rolled LHS into a 95 LHS? (3.5L noisy bearings) Have to use the pre OBDII sensors? What else? Injectors? Throttle bodies? Guess it will be easier when I have them side by side next week.
Planning on replacing the Timing Belt and Water Pump just because they will be easier while it is out.

Doubt this will help, but it's a starting point:

Maybe poke around the forums there,as there is quite a bit of info spread throughout...

Thanks, I am a member over there. Just bought the 99 LHS and was wanting to get some ideas before I got it here. it is about 150 miles away in Ft. Worth.

Also try dodgeintrepid.net. They do alot of 2.7 to 3.5 swaps

I got it home Friday and it looks like there are LOTS of differences. One throttle body instead of two, individual coils on the plugs, and etc.

I'm fairly certain its a completely different engine.

Best thing you could do is go hit up craigslist etc. for an Intrepid with a blown 2.7 and swap the 3.5 out of the LHS in there. It's much easier than you think and you end up with a cheap version of the Intrepid R/T. Bolt in and plug and play.

So many LH cars have had 2.7's blow and they are cost prohibative to fix. Go get a price on a used 2.7 engine from a junkyard. Yowza!! You can typically find a fairly mint 2.7 car with a bad engine for under a grand.

I have an '01 intrepid with a 3.5 out of a 00 300m. I was going to fix the 2.7. The swap was easier.

If for no other reason that curiosity, I'd like to see if it was just the upper end - or even just intake for that matter, that changed. I didn't ever get in to these cars, other than a general appreciation for them and lusting after a 300M Special and an Intrepid police package for a while.

My friend that has a junk yard says it won't fit. Hollander even has a different number for the bare block.
The general consensus over on lhforems.net is that it won't fit, the pan interferes with a sway bar or strut rod or something. I may look a little about changing the entire front subassembly. Before I go looking for a blown 2.7L I will find another 3.5L for my LHS. I am going to crawl under it and see how bad the crank is damaged first, I guess.

DodgeIntrepid.net has some pretty knowledgable people.

If you decide to part with the 3.5 car don't overlook advertizing it as a great donor for a 2.7 swap.

I bought a 300m with a wrecked front for $1000 and robbed the 3.5 out of it.
