I purchased a canton 6qt oil pan , melling high volume oil pump , and a canton oil pick up. Do you use the old tube that runs from the stock pump and pickup to conect the new pump and pickup?
thank Jim

 

If you bought the canton pan you have to use the canton pickup nothing else will clear the baffles in the pan.

There are different hp hv pumps, some with 5/8 inlet some with 3/4 inlets and you have to have the right canton part to work with your pump.

I agree with John, I also bought the Canton pan & their $100 blueprinted pump, assume it's a tweaked Melling is all, but I also purchased the 3/4" p/u assembly, upgraded oil driveshaft, spring, etc. I figured for $340 bucks for this pan might as well get the matching oil pump setup.

I'm just hoping I have no clearance issues with the Kooks stepped 1-7/8 longtube headers and BMR Kmember. One good thing I guess is you get to still use the same dipstick no problems (other than remarking for 6qts).

Good luck Jim, tell us how she comes together

 

seriously consider a standard volume pump. I know more people who have done damage with HV pumps than by leaving in high milage stock pump. Granted going with the higher capacity pan is a step in the right direction to avoid the damage a HV can do but HV it is still unnecessary.

 

The only thing a high volume pump might cost is a few horsepower when the extra oil is bypassed, that is unless there are other issues with the engine np.

A friend just bought a ss off e bay with a knock and the car had a new aftermarket pan gasket and high volume pump, it was a car dealer that was trying to hide the knock with more oil.

Why would anyone change a pump unless they are doing a new build, low pressure so the engine is already hurt. Add a new pump it will still blow up.

Have a canton and melling 55hv on my 600 rwhp car for 3 years no issues.
new build melling 155hv and canton pan.

On a high mileage stock engine I agree it's unecessary, bearing clearances dictate oil pressure and band-aiding high mileage engines with a HV pump is not the answer, in a built engine though having an HV pump is a no-brainer.

 

There are other factors besides bearing clearances that determine the volume of oil an engine needs to maintain pressure, such as cross drilled oil galleys and more than 1/2 groove main bearings. I have been running a SBC system1 pump ( http://www.system1filters.com/oilpumps.htm) and a canton oil pan for 30,000 miles without a problem. If you’re running a stock pan the pressure you run is more critical, because too much pressure will pump too much oil to the top of the engine causing the oil pump to pick up air
