The project 240 coupe needs a new powerplant. There are a few engines that i've grown to love through experience. Help me decide which one to transplant into the project coupe.
I have 4 Volvos, 1 wagon, 2 sedans, and my coupe.

Keep in mind this is my long term project, so it'll be done right and thoroughly photo-documented, like always.

VOTE AWAY!
Keep it clean, guys! Let's make this a fun, informative thread.

Here's the car, for reference. It looks a bit different now, though.
