When I installed them on my Gremlin...I would do so with the motor installed.....360/727..... If you get the front of the car about 18 inches or so off the ground you can get them in from underneath.... the driver side is easy....however on the passenger side you will need to get the header in then install the starter and then the header....works good for me....you will need to tie the header up or have someone hold it while you are installing the starter....a mini starter does work better....With a 727.....if you are using an after market shifter it is best to have that installed and working before you put the headers on.....
