ford used a remote solenoid on the firewall. chevys solenoid is on the starter and is notorious for getting hot and not starting. when people say ford solenoid, they are basically referring to a remote mounted solenoid.
yep and chevy was actually embarrassed about it and cam out with there own remote mount solenoid to fix the problem so you didn't have to put a ford part in a chevy. i have the part number somewhere if i toke the time to search for it.
