Timing covers are interchangeable but car cover accessories are -not- compatible with truck cover accessories.
well that sucks.
so if I buy a 6.1 from a car and want to move the
alt and air up(if they interfere with the frame) I will need to get a truck timing cover and air
unit and a different alt?
Yessir, that's correct. I bought a truck motor and wanted a car cover, been there, done that. Also, the truck timing cover will likely not allow for a car [front] throttle body location, you may be limited to the truck [top] throttle body location which may or may not be what you're looking for.
For what it's worth, I have a truck timing cover, non-eagle 5.7L truck intake manifold and a truck a/c compressor I will not be using. The intake port size will be smaller on the 5.7L intake when compared to the 6.1L head, you would likely want to hunt for an Eagle truck intake [2009+] to better match up with the 6.1L port size.
