I have a never run set of 5 on 5 14" wide 15" drag stars. also mounted on then is a set of 14.5 X 33.0 Goodyear tires.Check your PM's.

Draw3D,I think he is using a block mounted starter like I am and a block mounted starter turns the motor at a slow rpm and pushing 60 wt oil takes more than a couple of seconds to build up pressure.
all that coupemerc is suggesting is to get the oil through the motor before attempting to start it. We use exactly that procedure with Mark Vaught's 7.0 car. Roll the car out of the trailer and get it up on the jacks, pull the plugs and spin the motor until we see oil pressure. Put the warm up plugs in and fire the motor--with the galleries etc primed there is sufficient oil pressure by the time the engine lights off the squirt bottle and then begins running on the pump. We then switch to the race plugs and fire the same way on the line. Once the engine has been spun to get oil pressure the first time each day there is no need to spin it for more than a couple of seconds to get pressure and it takes that long to light anyway.

Here:I disagree with some of the posts, I don't fire my motor without oil pressure buildup and I don't turn on the mag if the motor isn't spinning, good way to backfire the motor and hurt the blower.
? As far as I can see everyone suggested just that--spin it with the mag off to get pressure and then spin it and flip the switch.
I recommend doing things differently than you listed. Check for oil pressure in the pits with the spark plugs out of it. Leave the mag off and the fuel shut off and crank the motor. That way you will not kill your batteries.
