I've seen where the SAE bellhousing used on the 60-66 style trucks and there seemed to be enough space for it. The 67-72 style trucks are a lower profile design so most likely there wouldn't be enough space unless you did some modifying or a body lift. I stuck with the pickup style bellhousing and SM 465 trans on my 478 conversion and quite happy how it came out because I retained the stock appearance.
