long box if u look at the brake linkage u can see where it would hit the end closest to the firewall. It just bareley hit it , a little grinding did the trick
I'm familiar with how the brake linkage is setup on an Advance Design truck, I've been involved with 2 smallblock swaps in them. Never had a problem with the brake linkage. However, the steering box is in the way of the exhaust, even with Rams Horn manifolds. Plus, the original bellhousing and flywheel will not bolt up to smallblock, though I will give you that the stock transmission can be bolted up to the V8 bellhousing.
