[DeTomaso] Cleveland vrs Windsor

[John Bentley (jab)]

Dan,

Just FYI, the reason the 4-bolt main cap was added was the main bearing
bolts were too close to the main bearing bore which allowed the outboard
part of the cap to lift off the saddle when load moved from side to side
and it was evident by fretting of the saddle prior to failure.  This
type of failure only occurred at very high RPM.

If you plan on spending a lot of time at high RPM (~>6000 RPM) maybe the
4-bolt block is worth the added cost....?  Maybe if we could talk you
into some 180+ MPH ORR time, that 4-bolt block would pay off!?!?!? ;)

Dan,

I wouldn't go out of my way to get a 4-bolt block.  You would be much
better off buying a local 2-bolt block rather than a 4-bolt far from
view.  Don't do the sight-unseen thing without sonic data.  The biggest
problem is like you say, shipping costs.  Even if the guy gives a money
back guarantee, he won't cover shipping!  Have someone local check it
out.

Jack,

The shop will be tearing it down and magging parts later this week.
This shop is telling me the Cleveland four bolt is no big deal, smaller
bolts and the drilling actually weakens the cast. They are endorsing a 2

bolt main Cleveland, as they say the Cleveland's hardly ever have main
bearing issues.
The deceased engine has part numbers D2AE-CA and the heads are D7AE.
