    camusmuse: Ive read some arguments againist the HV pump vs the std pump. Does anyone have opinions here?
    asking if any one has opinions on the hv pumps is a very hot topic. not that i am an olds expert, or even close, but i believe the only time you need more volume is if you have two low of pressure. both pumps will flow the exact same amount of oil at the exact same pressure, the restriction doesn't change.
    camusmuse: How about oil coolers? Pros and cons there? My plan(read idea), was to have a remote oil filter and making a encasing(coil) out of copper pipe to go around the filter) and use it like an oil cooler with water from the pump(like how the motor is cooled). Sounds mad scientist I know, but hey....that's how I think sometimes. If that's just the worst idea ever...please let me know, my skin is thick, and most importantly I am here to learn.
    for the oil cooler... buy one... making one your self leaves you open to having a huge failure in the middle of the lake. do you really believe you need one what is your oil temp at? if you are going to run an remote oil filter it would be supper easy

    in the hot boat article that timminator wrote, I think july "06" all the olds BB cyl. heads are basically the same, the only differences are valve sizes, and he really seems to know the olds motors in boats. so I would say with the big valves they should all flow about the same. also (at least around me) machine shop prices are so high that after all the work and all the $ in new parts you would be better off buying a set of aluminum heads from edelbrock.

    heh...my oil temp is room temp right now.....Im still in the planning stages. trying to absorb as much info as possible. I kinda thought my cooler idea was a little silly, but have seen sillier things work....thanks for the info

    I have that edition... timminator said something about the Old's being considered the "Redheaded Stepchild" of GM marine engines... I got a huge laugh out of that one

    BTW... I ran the stock oil pump for 13-seasons with a welded on pick-up and the relief spring shimmed with 2 flat washers... also, it is a good idea to add a second gear chamber cover to stiffen the pump... some claim it is known to flex... hard to believe, but apparently so

    being redheaded myself....I like my 455's even more now.....

    I tried to contact timminator through pm here to see if i could get ahold of that article....no response....think there might be a copyright thing there or something though....oh well

    thanks for the tips on the stock oil pump...they will go on my "list"...

    Default H/V vs Std oil pump

    Here is my theory,

    I don't see the pump as a H/V pump but "High pressure" pump.

    You get a H/V standard pressure oil pump and H/V high pressure pump.

    The H/V-High Pressure pumps is normally for Diesel engines.(tight clearances)
    H/V - Standard Pressure pumps gas engines

    Why do people shim the std pump spring? You can't turn the pump into a H/V pump by diong it. You shim the spring to keep the bypass closed for longer ie. more pressure to mains etc.

    Why I use a H/V - H/P pump.

    With the oiling mods on the BBO, restricters, bigger clearances etc you need more pressure otherwise at idle, very low oil pressure and when you hit the throttle no oil on the crank.The spring opens a valve to release pressure because to much pressure isn't good. It bypasses the filter as well and the oil doesn't get cleaned. Without the restricters and Std or H/V pump the oil just goes to the heads.

    Before I spun the big end on my BBO the Oil pressure was 4 Psi at idle and 6 Psi at 4250 RPM. Bearing was spun due to incorrect clearances, over revving when the pump unloaded and a dead spark plug.

    Just my opinion.

    Default my two cents...

    It seems to me that a High Volume pump becomes a High Pressure pump, when the passage(s) become restricted. That is, pressure is a function of volume and restriction.....much like a jet pump?

    Now restricting only part of the equation(like what I perceive is being done to the Olds motors) would actually create both high volume(bottom end) and high pressure(top end). This would require a "Heavy Duty" pump...which maybe what the upgrade really is???

    That all could be total fiction, but that's how it all has been making sense in my head. Dangerous "waters" for sure...
