<VV> LOWER SHROUDS

[James Davis]

Ultra Vanners are about 50%-50% split on lower shrouds.  Without then, the 
engines seriously over cool on the down hills in the mountains.  Most run 
the lower shrouds because of the coach heat.  I am able to maintain 30 
degree differential between outside and inside running headers and lower 
shrouds.  I would bet that most the Ultra Vans that do not run lower 
shrouds do so because engine oil leaks which renders the engine heat 
useless.  All Corvair powered Ultra Vans came with normal car engines (RG, 
RN, RH, RV, RW, AC, AD, AG) including the car's exhaust system.
