Lippy, Pat's point is well taken-
unless you track the car.
I'm sure Brent would agree-nice to have but problematic.
Here's why I say that:
In the late 90's, I bought a complete Accusump (2 qt.), hoses and mechanical valve and began the planning of the installation. I intended track use and long lay-ups and was convinced I 'needed' one.
The pic Pat shows highlights the first problem-many guys mount them on the front X-member. The first time you have to check / change timing, you will hate yourself. Access to the damper and it's bolt is lost. Not good for adjusting solid lifters. Sure you can bump the starter to open and close the correct valves but there are other times when you need to change position by hand.
So being a genius I figured I'd mount the tank behind the driver seat, next to the tunnel. Then run the line forward against the tunnel, to the mechanical valve at the front edge of my seat-close enough to reach down and open/close it. Then more line forward, out the trans tunnel, along the block side to the block adapter. You don't want a remote filter because in ERA's there very little room for hoses and fittings going up and down. Access to your water pump, a leaking rad hose and the fuel line from a mechanical pump is now punishing.
In short it's an overengineered, impractical non-necessity,
unless you race. In the end I decided against adding 1000 fittings of all geometry and all the complexity. I sold the unit to a pal with a different car.
If you're a hands-on owner, you'll regret it for negligible benefit. If you pay to have work done, you'll pay much more (hours) while the guy has to remove half your
oil system to do simple maintenance on your car.
And the way to live without one is easy. Many guys like Pat live just fine without it. If you lay the car up for 2-3 months the easy thing to do if you're worried is remove the distributor and with a speed wrench, spin the
oil driveshaft and you can get 40 psi on the gauge easy. Then start in the normal manner and run it.
I found out I worried for nothing as that's the way I maintained the motor and on track (road course, autocross, drag strip) my Canton road race pan did a great job of keeping
oil pressure up. If you hole the block, having oil pumping in isn't gonna save you much until you shut it off.
In short-you probably don't need the expense and complexity. A mild 482 at 600HP is not a highly stressed unit. And you
certainly don't need 12 qts of oil so you can sleep tight at night.
