Hello all,
 
    Just read an article on the oil thing. The problem  is the Zinc and 
Phosphorus that will kill the catalytic converter if the engine  starts to burn 
oil. A friend of mine and I just replaced the catalyst on his car  for this 
reason. They found that flat tappet engines with very high valve spring  
rates can have problems. Stock or even a bit more engines just don't have a  
problem. As I recall the oils made for diesel engines, such as Rotella, still 
 have these additives. For engines with roller cams and tappets it is 
totally a  non issue.

There  have been some concerns posted latey about using todays oil in our

Roadsters AFTER they have been broken in.  The concern was they  were 
missing
the correct kind of additive package to provide proper wear  care for our 
cars,
and that you needed to get a specific oil  additive.  I asked my engine guru
who is careful about debunking these  kind of things.  His response:
"Bullshit.  This was started by a  Nascar team (Joe Gibbs) who had a cam go
flat and decided it was the  oil.  What it probably was was excessive spring
pressure.  None  of my customers, nor anyone else in the industry have 
reported
any problems  related to excessive wear due to todays oil.  I think it is
marketing  BS to sell a product."
I continue to run Mobile 1 without concern.

There's been  some threads on the assembly and break-in of "new" engines. I
noticed an ad  from Comp Cams in the latest issue of Chevy High Performance
for a new  break-in oil (*http://tinyurl.com/ygtkpxl*) they're now selling.
Looks like  a great product to me.
They also offers assembly lube and spray. Knowing  Comp's reputation this
stuff is worth using,  IMHO.
