I got an Armando pan for my winsor. Think hard about going with the Alum pan option. If you can swing the extra price, it is worth the investment.

Note: In fitting up my pan, I found the crank hitting the scrapper (427 CID). So a little trimg was needed to get it to fit. Dry fit the pan, manually turn the motor, just to make sure everything fits. Beats having to pull the pan once installed.

Actually the thinking on the pumps is just the opposite of what you think it is.

You want the high pressure pump for sure, this insures the oil pumped by the pump is delivered to the block and not recirculated. It also prepares the motor for more rpm, the old 10 psi per 1000 rpm rule applies here. (Its a Smokey Yunick rule).

The standard volume pump is preferred unless the clearances in the motor are set "loose". So long as the motor builds 10 psi additional oil pressure for every 1000 rpm increase in motor speed the volume of the pump is adequate.

Thanks Guys,

Dry fit the pan, oil temp weld o let and High pressure spring.

Only one thing George I didnt see a high pressure spring to the Windsor pump ? I have to check it again. I did install a high pressure spring and high volume pump, and 10 quart pan on 9138 and no problems with oil racing it at Pocono on those banked turns.

Ron,

I took a brief look at the Melling catalog & to my surprise the 351W & 302 use different oil pumps. I've never built a 351W, I just assumed they would use the same oil pump.

Melling only sells a high volume/standard pressure pump for the 351W (p.n. M-83HV). That makes no sense at all to me, not for a high rpm racing motor.

It takes more pressure to force more fluid through a given size oil system. So if you increase the volume of a pump without raising the pressure of the relief valve (stiffer spring) then all you are going to do is recirc more oil at high rpm, you won't supply more oil to the motor. Building high volume/standard pressure oil pumps has never made any sense to me.

For compaison, the Cleveland oil pump is p.n. M-84AHV, it is BOTH high volume/high pressure.

Melling still makes their standard volume/high pressure pump for the 302 (p.n. M-68A). That is the pump I had in mind for your application.

So I guess the question is, which pump does your block use? A 302 pump or a 351W pump?

Another thought, Ford sells a restrictor kit for the Windsor, it restricts oil to the cam bearings and the 2 lifter galleys, if you're going to race this motor that would probably be a good thing to install as well, especially the restrictors to the 2 lifter galleys. Of course if you've had the lifter bores bushed & set with tight clearances then a restrictor kit isn't needed.

George,

My block is a 351W SVO G block 9.2 deck. I orderedfrom SUMMIT a MEL-10833 which fits my application and the AVAID PAN a pick up today. With a MELLING OIL Pump drive IS83. I like your idea of the restirctor kit ? Got to CONSULT with Olsen. He want to leen toward hrdraulic roller cam .. he feels a little more reliable and durabilty is better ... I would agree with that .. who wants to be under the hood adjsuting rockers every week.

So do you see a High presure spring for this pump .. I think we will see 6500 7000 rpm safely
70 psi isnt going to happen with a std pump ?
