Ahh, this is where I am still learning. The bolt pattern is the same yes, but the depth is different with at least two different options over the years. I went with the 351/400M iron bell housing from a 80's truck with a shallow depth of 6.25" for use with big block short input shaft trans. With my truck bell, I also had to use a McLeod input register spacer (choke) ring with my McLeod HTOB as it was smaller than 4.850". (That lesson cost me a new pilot bearing one afternoon).
The newer 460 90's Truck aluminum bell pic I posted above (i believe) is deeper (someone can maybe confirm this here) than 6.25" without a block plate, which me now thinks allows one to use the standard length TREMEC input shaft to avoid purchasing the short input kit or avoid the use of the trans spacer also available when using the standard length TREMEC input shaft.
In any case my chassis clearances required me to use the shallow 6.25" bell. But I was curious to learn more about the modern alum bell pictured and understadnd what hydraulic TOB set up it uses.
