new rebuilt 5year ago. turns fine, no rust.Any advice for the first start of a big block mopar?
you will definately want to prime the motor. You will need to get a priming rod tool (www.manciniracing.com) remove the distributor, and the oil pump drive gear just below. (this is easily done with a screwdriver and magnetic picup tool.
Then insert the priming rod and spin the rod with a drill until you get an oil presure reading on your presure gauge. (if the gauge is electric, be sure the key is on) Spin the drill in the same direction as your distributor rotation.
You can have a buddy turn the motor while you prime it to get better lubrication. (you will need to reset the timing if you rotate the motor)
Once primed, replace the distibutor, and oil pump drive gear. (be sure to return thrm to the exact positions they were in, it may take a couple tries with the oil drive gear but its important) Make sure the carb has fuel, give it a couple shots of starting fluid to help it fire till the float bowls fill.
Once started give the timing a quick check (it doesnt need to be dead on, and this needs to be done fast, just make sure theres no pinging, or backfiring).
Now you need to break-in the camshaft, this will reqire you to run the motor at 2000rpm for 20 minutes, and you will want to rev the engine up every minute or so to help spin the lifters.
After the 20 minute break-in let the motor cool and then change the oil and filter before restarting.
Now you can go back and adjust the timing, and get the final tuning done.
Remeber to make sure to do these things before firing the motor:
Check oil
Check radiator
Check fuel
Check Battery
Check firing order
Verify that static timing is set (this means that #1 piston was brought to TDC of compression stroke, and that the plug wires were set according to the location of the rotor to dist cap)
Make sure distributor is just loose enough to turn by hand
Inspect for any leaks (shut down if need be for safety sake)
Items to have on hand for break-in:
Fire extinguisher
Box fan (I set this in front of the radiator to help with air flow)
Screw driver, and a small assortment of tools for minor adjustments to carb, etc.
A good friend to help watch you and the engine
a 6-pack in the fridge, for celebration after a good break-in, or to ease the pain of a failed attempt.
Turn it over a few times without spark, to let the oil circulate. Disconnect the coil or whatever.Any advice for the first start of a big block mopar?
yeah, sell it before it goes bad three weeks later.
get a little Marvel Mystery Oil and put about 1 tbsp. in each cylinder through the spark plug holes. Fresh oil in the crankcase is a good idea, too. Disable the ignition and turn it over a few times to get the oil through the passages. Fire it up and enjoy the rumble. Let it idle for at least 5 mins to ensure no loose fasteners or other problems. BTW, the Marvel is to reduce piston friction on first startup and ensures rust cleaning internally. just bcuz theres no rust on the outside doesn't mean none inside. Cylinder walls are very smooth and rust very quickly when they are not in use.Any advice for the first start of a big block mopar?
Honestly switch to Chevy. Seriously no hard feeling just easier to find parts and work on.
go crusin or paint it
That would depend on where or not it is in the vehicle. If it is then make sure all the hoses, lines, wires, etc are hooked up properly. Make sure you have all the additives and oil at proper levels. It would be a good idea to be sure your battery is fully charged. You shouldn't have any trouble. A good rule of thumb is take it easy for a while till the rings and seals get seated good and the valves set good. A good driving speed for a week or so is around 50 to 55 mph. not over that
NEVER CRANK A DRY ENGINE. THE BEST WAY TO LUBE IT IS PRIME THE OIL PUMP. PULL THE DISTRIBUTOR USE A DRILL AND A PUMP PRIME SHAFT OND LET IT SPIN FOR A MINUTE REINSTALL DISTRIBUTOR. PULL ALL PLUGS AND PUT A VERY SMALL AMOUNT OF OIL IN EACH CYLINDER. THEN TURN THE MOTOR OVER BY HAND(SOCKET ON CRANK) THEN PUT PLUGS IN AND FIRE MOTOR.
