I love my cleveland in my bronco. It fits like it was made for it. No butchery at all. I do have a body lift and I know that helps a lot with any clearance issues. I think the stock throttle linkage would be a tight clearance without a bodylift, but I use a Lokar pedal and cable linkage. The Sanderson FC3 headers are great, use a 351m\400 rear sump 4x4 oil pan or an aftermarket pan.
As for the common misconception about clevelands having no low end torque, thats a load of BS. The torque ratings for the C and the W are equal for the 4 years the cleveland was made. True the 4v heads do love to breathe at the upper end, but the 2v heads work far better than any stock windsor head.
Edelbrock just came out with some nice aluminum 351c heads and an air-gap intake. Plus many other aftermarket parts are available. They are great engines and I will only run clevelands in my bronco from now on.
