We getting ready to pull the manifold and carb out on our pantera. usually this wuld be very simple buuuut, my dads nitrous system is set up with a plate between the the carb and the intake maifold.
my question is, does anybody know how to take off this plate? or more importantly is there a danger to disconecting it? like will nitrous gas be slowly leaking into our garage?
My asumption is that we can either A) unbolt everything and just push the plate off to the side, or B) disconect the lines to the plate and pull it out as well. But im just guessing that so if anyone knows better corrrect me.

also does the maifold have to be torqued when its put back on? and if so does anyone know the torque specs and pattern?

Thanks in advance

Hi Zybe,

Removing the nitrous plate should not be a problem, as the nitrous (and gasoline) is controlled by a solenoid. As a precaution, just close the valve on the nitrous bottle.

Below is the torque sequence for a 351C. Torque for the cast iron manifold is 21-25 ft-lbs for the 5/16" bolts, and 28-33 ft-lbs for the 3/8" bolts. If you have an aluminum intake manifold, check with the manufacturer for torque specs.

Why would you take the intake manifold off?

You said you were just removing the carb. Reinstall of the carb should probably use a new gasket,because the car has sat for so long. And although there must be a torque value for the carb nuts/bolts, just common sense and even all-around torque will be fine.
