What Oil pump should I get?

[69clark]

1. Should I get a High Volume or standard volume pump?

2. What is a good brand? Ex. Ford racing, Melling, ???

3. I read somewhere that if I get a Ford Racing high volume pump I may have to make modifications to the oil pan. Is this true and if so what kind of modifications? Or will it bolt in?

Thanks Guys

stock oil pan = stock volume oil pump

larger aftermarket pan = high volume



there is a thread within the last day or 2 in here about this..... dig it up theres lots of info in there

high volume pump will suck all the oil out of a stock pan. If you get a high volume you need to get a 7qt pan, or run the risk of sucking the pan dry at high RPMs.

Well I guess I get the idea. I feel kinda dumb now! I always want to go bigger and safer than I need to but I glad I asked on this because I may have ended up making a mistake. Thanks guys!

This leads to the next question. Can I run a stud girdle with the stock pan?

Theres nothing wrong with running a high flow pump. You just need to get the corresponding part, our stock oil pump are like our h2o pump they can supply high hp/tq cars. I have no clue on the girdle though.

my canton girdle will not clear a stock pan......

Been a long time since I have seen any discussions on this topic.

Years ago, lots of peeps would not use a high performance pump on a stock short block because of the close specs on rod & main bearings.

A motor set up for racing is gonna have a fatter spec on the bearings.

The thinking here is the high pressure and close spec in the stock motor can cause a wash away of the bearing surface.

The race motor needs the extra supply of oil due the the extra clearance.
