10 sec. 318?

Hmm, sounds like a good place to start. I'll have to scout around and see what I come up with. Did you end up having to change motor mounts or anything? Admittedly the car I have has some rather "curious" mounts consisting of angle iron and square tubing to get the mounts where they need to be for the 318. I'm pretty sure they never changed the K frame from the /6, but I will definitely change the mounts when I swap the engine if not the whole K frame. I wouldn't trust my welds for much, especially not a high power engine twisting on them.
