What to do to put b21ft/m46 in 1969 142 140-160 1969

Hi all,
I have a b21ft sitting in my garage and a 142 sitting there also they look like they should fit, but I need to know some info on swapping them together. Do I need to cut a tranni tunnel out of a later 142 or a 240 so I can use the m46 shifter, (or could I just cut a hole where the shifter will poke through)? I want the engine tilted because I don't want to have to modify the intake manifold for the brake booster, is there any reason why this wouldn't work?
I don't want to hear "just build up your b20, a lot of power can be made from one" because I know that but I want a turbo and NOT a b20 turbo. I do have a welder and many of the other neccessary tools to make all the necessary changes.
Has anyone (here) done this swap, (even with a NA engine)?
Please respond asap as I want to get this started as soon as possible (winter project).
Thanks in Advance!
Sean

I've seen OHC engines in 140 series cars, but usually in an upright position. I'm not sure about the clearance around the upper wishbones. The 240's have a lot more room with their strut suspensions.

Do an archives search. This was talked about a week or two ago. If I remember correctly, you have to use the B20 oil pan, install the B21 upright, and fabricate your own motor mounts (or motor mount adaptors).

Wish I had thought of this when I had a perfectly good OHC engine sitting in an old parts car outside, and was scratching my head over my pooped B20....
