Luckily, I have the inner fenders removed so I can just stick my head in under the fender and see the clearance or lack of. I'm pretty sure that the air cleaner will need to be modified.

It is set up to clear the choke housing on a Holley carb, so I think I can trim the base down some based on the pictures I've looked at. That might gain 1/2" and just might be enough.

Worst case, I'll have to drop the engine down a little. The motor mounts are still just tacked to the chassis and I have about an inch that I could use before the accessory drive hits the steering shaft. I would rather not do that for a lot of reasons, though.
