Federico I have one here if you want me to take measurements? Can you receive mail in Uruguay - I can ask my friends here how they send stuff to their home.

If he had a 603 in there previously then maybe so. Just want to cover all the bases.

True enough. I recall that there are two sets of threaded holes on the IP side of the engine for the mounts. Maybe using the wrong ones?

Could be. Same is true for the 603.

I swaped a 606NA , as Alan mentioned there are several sets of holes to the engine mounts. I used the mounts in the pictures.

Left side is the 6032235504 and the Right passenger side is the 60222308 I can find out the last 2 numbers if you want. But I got these originally for a 603 engine that I did use.

the location of the chassis brackets for the round variety and trapezoid mounts are different and the chassis bracket for the G606 trapezoid mount is different than other variants of the trapezoid mount bracket on W460/W463

Thank you for the imput guys

Mine is an early 460 so it originally had the round type engine mounts.
I made from scratch the engine mounting arms to suit the chassis brackets (which I made a slight modification but had not changed the position)
Things mentioned above were done when I did the 603 swap.

Upon further inspection I realized the problem is the engine inclination.
I can't lift it up, and measurements from chassis rails to crankshaft bolt are the same on both sides, so it's centered..
Ther's two sets of holes on both sides of the block and while having the 603 and 606 side by side I checked and the holes are at the same position on both engines.

I got away with it because of the 603 intake being way smaller.

My intake has plenty of clearance with the brake booster. Maybe we have different size brake boosters?
Position in the same as far as I can tell

Thank you for the photos

Actually It could be very helpful to have the measurements from the lower set of bolts to the base of the mounting arm ( where it touches the rubber mount)

But then I imagine that having different chassis brackets (located on another position), the measure would not be relevant


Thank you

Post some photos at different angles of the motor in place. Maybe we can better help with a visual reference.
