Looks like it's a no go. I did a CAD (cardboard aided drafting) mockup, and the solenoid hits the block, even if the big lug is removed.

From the side, I had to fold down the solenoid to fit.







I taped the solenoid on top so you can see how high it sits, and it completely obstructs the lug sticking out the side of the block.



It's hitting the side of the block, pushing the template away from the block, so the block itself interferes with this starter. Too good to be true, I guess.
