Thanks for dropping in to check out the images and give a comment. You’ve discovered what a lot of users of adapter plate mounts have and that is that their use comes with an engine height penalty in most applications that does not permit U-joint operating angles to be optimized in a bolt-on manner. Your case would be even more amplified due to the longer wheelbase of your Suburban compared to a short bed C10, especially if it’s lowered, The engine mounting brackets in the Hooker Blackheart 1967-72 C10 swap system were designed along with the transmission crossmember to provide desirable U-joint working angles on trucks that have been lowered with the typical 4”/6” drop kits that are commonly used on these trucks. I don’t recall what the relative engine inclination angle that resulted from that effort is off of the top of my head, but I will find out and report back on it for you.
Posted via Mobile Device Follow-up: the resultant engine inclination angle ended up being 3.5 degrees relative to the bottom of the frame rail.
