1964-66 A body Gen 3 motor mounts

Is that a 5.7 from a truck or car? Without changing K-member you run into clearance issue if it’s a car motor. As the accessories are at the bottom. The truck puts them up top. FYI I’m not trying to be a jerk just from experience.
It is out of a car. I'm using the holley alt relocation bracket, removing the ac compressor, and the power steering pump. I'm fabbing an aftermarket LS1 idler pulley to go in the ps pumps place. Should be good. thanks
