Unbolt the trans from the bellhousing and see how many rings are on the input. If it has no ring, two rings or three rings it's a good trans to run. One ring stay away from, very weak. And yes it is a Saginaw. I have ran them for years in my GTO and like the steeper ratios, especially with high rearend gears.
