Can Sea Foam help get my 1967 Firebird running? [SOLVED]

I have a 1967 Firebird w/ a 455 sitting for about 15-18 years. Before I start the motor what Sea Foam products could I use to help? (I know I need to change all fluids and dispose of old gas.)

Hi Raffi. Based on the information in your question, here are some ideas to consider: 1) It would help to add half a can of Sea Foam High Mileage to the oil crankcase to reliquefy old oil residue, 2) a can and a half of High Mileage to a low amount of fresh tank fuel (start with only a gallon or two in the tank), 3) a can of Trans Tune down the ATF filler neck, and 4)  I’d remove the spark plugs and spray a healthy burst of Sea Foam Spray into each chamber, crank the engine 4 or 5 times to pull the Sea Foam mix into the carburetor circuits, then let it soak overnight before starting.  After you get the engine running, spray the rest of the can of Sea Foam Spray down the carburetor throat (clean intake valves and chamber areas – see can instructions). Let us know how it goes!
