I'm planning on installing a B230F into a '61 P210, and I'm thinking it would fit best if it was slanted like the stock B230 engine. Mounted upright is an option (I mounted a B21 upright in my '65 122), but there is a lot of room on the passenager side, and less room on the driver's side (see photo below). The reason I need to know the degree of slant in the engine is because I want to use a M41 transmission in it, and I'm going to have to cut, rotate and reweld the bellhousing to fit the slant angle like this (this photo is a M46 bellhousing modified to fit a B20 engine upright. Same idea but backwards):




A dry fit with a B21 head with engine mounted upright:



Just a photo of the P210:



I think the slant is between 10 and 20 degrees? Any ideas would be appreciated.

Thanks-
