never cover the radiator.. even my dad in his rig climbing through way below zero in northern maine learned a lesson on this..
never ever cover the radiator.
given the SHO is a flyin sideways at 1500 degrees on the backside...
the problem must be something stuck open in the cooling system. Try checking thermostat, even fluid levels, bad guage, clogged heater...all kinds of stuff.
the sho is the top 1 in all crazy sideways hot rods.. there is not a chance in heck it takes awhile to warm up...unless there is an error. find the problem.. do not cover it up.
