[DeTomaso] Oil pressure help needed

[Asa Jay Laughton]

Chris,
In my experience (what there is of it), you'll be fine.  My first 351C 
rebuild in the Mach I had pressure similar to that and lasted nearly 80K 
miles.  I'm sure the engine failed for other reasons, not oil pressure 
too high.

For what it's worth, at the time all we did was pull the stock pump, 
disassemble it, clean it, smooth out all the wear marks on the cover and 
the gear bottoms and put it back together (yea.... I was even -cheaper- 
in those days), and it got me 85 lb nearly all the time.  As the years 
wore on and I put lots of miles on the engine, the pressure began to 
come down little by little, but it was always in an operable range.

Carry a spare pin for the distributor and have a blast on the drive to 
Reno.  Wish I was driving -my- Pantera there.

The mechanical gauge I installed a while ago shows about 60 at idle and 65 to 70 at normal cruising speed on the freeway.  When sitting idle, however, when I rev the engine the mechanical gauge goes to 85 at about 35000 rpms.
