Yes it was originally a 6 cyl. car and the mounts came with it along with a 360 and a 727 trans. I can not get any info from the guy I bought it from because he passed away a couple months ago (way to young, 55) and the guy he bought it from also passed away but not sure when. I believe that every thing I got had been in the car before but not really sure. Did you put motor in first then put tranny on?
