wrench 87 I use a HVHP
oil pump in my car with a harden
oil pump shaft. It also has a 100 psi spring in the pump, not 80. Something to think about, how many motors have you seen blow up from high
oil pressure??? We don't know what clearances are being used on this motor??
If blueprinted from old school, .003" mains and rods. You better have a HVHP for this kind of looseness. I run a shelby block with under .002" on rods, BBC ones and .0022 on mains. This motor expands about .001" when hot. I just replaced the crank rods and pistons with a stroker kit from Barry R. Kit works great, bearing clearances where on the money for what I run. FE bearing are small and narrow for the rods in FE motors. I want all the pressure and oil I can get to this area to float the rods and bearings off the crank surface. I have raced the motor for 7 years and the distrib gear is just fine. All you have to do is make sure that oil is getting to this location and lube the 2 gears.
A peroiler would be another thing to add to your motor. This will stop dry starting and bearing wear. I have a 3 quart accusump for this. Works great. When cold I don't race the motor, I am getting about 125 psi when cold, even with the 100 psi spring. Let the oil warm up alittle before moving the car or changing engine speeds. Just a thought that I do. I am going to a drysump system on my next motor, 498 shelby and run the same pressures. I have limiters in the heads to keep most of the oil down stairs. Rick L.
