Just Bought a 65 Barracuda that sat for over 20yrs.

Thanks for your suggestions.
I actually was foucsed on the engine when typing the initial list, but yes, I am planning on dropping the tank, draining it, checking for moisture, rust & varnish as well as the condition & function of the fuel level sending unit & the conditon of the filler neck & rubber seal! Hopefully, being in Tucson AZ has mitigated levels of rust & rot in the places that really matter. So far, the battery box & water intake are the biggest rust victims, unless I count the Radiator cap & thermostat which had nearly every bit of steel coverted to a pile of moist rust! No more evidence of hard matter could be detected that wasn't brass!
I appreciate all the feedback!
It helps me to know I'm on the right track!
Also shows that hawe have quite a bit of work before this car could be simply used the drive to the track
