Series III GM 3.0L Engine?

[smooth]

I am new to this forum and have recently purchased a 74 Series III 109. I went to order my first parts and realize that that the motor in my Rover was manufactured by GM. Block stamp shows 14097080 GM also stamped to the right of that is 98 and Made in Mexico. Supposedly it is a 3.0L 4 cyl. My initial research says GM manufactured these motors for marine and industrial (typically fork trucks) purposes and not for automobiles. I have many unanswered questions. Has anyone heard of this conversion? Is this a typical conversion for a Rover? I saw references of this motor used in fork trucks in England, do you think this was done in England?

Any help or opinions would be appreciated as I try and figure out what I really have here. I still love my Rover and it runs great! Thanks for your help.

Is your Rover from England? (you know what I mean...) If so, you might be dealing with an engine available in the UK and not the USA. What year is your Rover?

I'm not terribly familiar with the Scotty's adapter or which GM engine it mated up to the Rover transmission, but it might be worth Googling "Scotty Adapter Rover" or something similar.

Also, TeriAnn's land rover site has good engine conversion info on it, including the GM conversion, which I believe she runs in her Dormobile. Might check that out. Google " TeriAnn Wakeman Land Rover ".

Thanks Mark. I'll get started on those two topics right away. Looks like I have a lot of learning ahead of me.

Sounds like it might be one of the 3.0 mercruiser conversion from Robert Davis. He's doing Mercedes conversions now but might be be a good place to start if you have some questions.

You need this!! Just kidding.You have to be careful with those Scotty's adapters if they are not checked with a dial indicator and adjusted with adjustable dowels. The input shaft bearing can go away in a hurry. When that boat engine rattles apart the transmission consider swapping in a GM truck four speed or nv4500 and adapting to your t/case. I have been running this combo for a few years. Works great.

Thanks for your help everyone. Looks like I do have the Robert Davis conversion. At least now I know what direction to look in. Does anyone else have the conversion? How has your experience with this been? Still not sure where to get parts. Auto parts store or boat dealership?

What's the advantage of using a boat motor over one that was designed for a vehicle?
