forgive me for asking a question that may have already been answered, but what did you do about the oil pan? I saw mentioning of modifying the stock pan, but I take it there is no stock pan that will allow this engine to bolt into a first gen 4x4? I may just modify the stock 3.0 pan to fit the 3.5.
There isn't any practical way to fit the 3.0 pan on a 3.5. Block width is different for starters. I had to modify the 3.5L pan to clear my hi-steer steering. You might look at the early Montero 3.5L pan. I have no idea if it might fit. I do Montero Sports, not familiar with the Montero undercarriage.
... I have recently procured a 3.5 sohc from a 2002 2wd sport. As far as I have been able to tell, This engine should bolt up to my existing 5speed and use my existing flywheel and clutch. It looks like the mounts will need to be modified by about 1/2 an inch. "I've got a guy" that can do a complete custom down pipe back exhaust for around $250 to $300 (he's REALLY good a that price too!) And I plan on megasquirting the thing as far as fuel and ignition.
Don't know if the old pre-96 stuff will bolt up to that engine. If everything bolts up, you'll need the 3.5L plate that goes between the engine and bell housing.
DOes that about cover it? aside from the cooling issues you ran in to?
It you MS it that will take care of the heating issue. The MS can do timing.
... Plus, if you ask me the 3.0 is a bit underpowered for even a stock montero.
The 3.0L is more efficient. Much better choice if you're worried about mileage. The torque in the 3.5L is real nice, though.
