[DeTomaso] Why use a 351 Cleveland rather then a 351 Windsor??

Sat Jan 3 10:20:23 EST 2009

My theory is it would save the engines that bend pushrods.

There's a pretty good thread on www.351cleveland.net that discusses oiling.
The title is 13.5GPM.  Most of these guys are drag racers, so they're
actually turning 7K or 8K RPM on a regular basis.

One of the guys, Wydendorf, even sells a kit to bush the lifter bores.

If you do a search on www.351cleveland.net, you'll find other threads on
oiling.  They bring up some ideas that we don't normally discuss.  For
example, they claim it's important how the front cam bearing is installed.
If you install it by the book, it bleeds too much pressure.  They say it
should be as far forward as possible.

This was discussed some time ago and I think most engines waste the  
front bearings, which goes against the theory of the external feed line.
