Firing motor after a long sit!
So I built the 350 4-bolt main in the 67 about 5-6 years ago. It has never been driven but before my last deployment it was run weekly to keep it going.
Now, 2.5 years later I have pulled the fuel tank to replace with an underbed tank. Im about to get ready to try and fire it again for the first time since before I deployed. What should I do before attempting to fire this engine that has sat for so long? It does turn over easily nothing is frozen... Im looking more along the lines of the carb, oil, etc... |

Re: Firing motor after a long sit!
id replace the oil and oil/fuel filters then just to be safe after you put fresh oil in id prime the oil pump before you started it

Re: Firing motor after a long sit!
Since you already turned it over, I would just pull the plugs, squirt some oil in each cylinder, pull the power to the coil, and spin it with the starter for 30 seconds, put the plugs in and the wire back and fire it up. Might replace the fuel filter first. I would not replace the oil/filter until after it started. All this assumes it has been in a relatively dry place. If it is stored outside under a cover I might worry more about rust and moisture.

Re: Firing motor after a long sit!
I let mine crank (fuel pump off, or coil wire off) for as long as it takes for oil pressure to come up to operating range. If you didn't add fuel stabilizer, you -might- consider draining the bowl first, it's probably full of that powdered fuel residue.
I'd change the oil -after- you got it up to operating temperature. Any junk in the motor will wind up in the oil in the first few minutes, and the "protective" value of new vs old oil in those few minutes is probably negligible. Drive slow at first, the tires are probably square on the bottom (and if its been long enough, they could separate and fail).
