Judging the car from a pic is hard to do..However overall,the doors paint peeling and bubbling or what ever is doing so could be a really bad prep job,or filled with gobs of bondo,the wet floors could be door weatherstrips and A pillar strips,may also be heater cores. Do all lights and gauges work,does the tail lamp that retracts work properly,get the car in the air and check for sill and floor panel rust and any other damage.with the engine swap is the stock trans used,and does it shift fine,that motor BTW looks to me to be an early Lincoln continental 460 61-64 era with the overflow tank gone,note the generater and not 70,s alternater ,perhaps they ran the original ,but I doubt it...To me it may be the someone doesn't know what their talking about ,I may be wrong about the engine ,but it surelooks like a 460 to me!//run the engine #,and take the car where you can see more undercarriage....As a driver its up to you......
