Chevy BB oil filter.

[JAF]

Hi Guys,

I'm looking for a recommendation on an oil filter for my newly rebuilt motor. It's a Chevy BB 427 bored 0.070 over. It was built by a local race shop and dynoed at around 450hp. The builder (who has a really good reputation) wants me to run Mobil 1 15W-50 because of the way the clearances are set in engine. He also plugged the oil bypass in the block and installed high volume (not high pressure) oil pump. My oil pressure runs about 40psi at idle when warm and +60psi otherwise. He also recommend I run a Fram HP4 filter. I am looking for some other filter recommendations. It needs to be capable of high pressures. So far I have come up with Fram HP4, Wix 51060R, and Baldwin B279. I'm leaning towards the Wix just because of availability. The car sees only a 1000 miles a year and I change the oil once a year just before I stop driving it before winter.

Thanks.

I would run one of the truck size 2 quart filters. I think the Fram part number is ph393 but check in the oil filter manual for the proper number. most all oil filter companies make the truck filter. Look in the Chevrolet truck section

Wix has an excellent standard-size filter, with high-pressure, high-flow capabilities, and it has an ADBV. It's the 51620. Wix 51620

And, of course, there's the ACDelco PF35L, which is a synthetic media high-performance filter. I use these on my C20, which has no bypass (that's the way I built it). ACDelco PF35L

Another excellent filter is the Baldwin B6-HPG, a high-capacity, synthetic media high-performance filter. It's the Chevy version of the B2-HPG (Ford) I cut open a few days ago. Baldwin B6-HPG

The Donaldon P166564 uses Donaldson's Synteq media, and is the Chevy version of the P169071 (Ford) I cut open a few days ago. I'm sure it is very high-quality. Donaldson P166564

With a blocked bypass, make sure that your oil pressure at idle is at the normal operating temperature level before you get aggressive with the throttle.

Hope this is helpful!

I would run a Ford filter with a bypass. Purolator or better for flow.

Personally I think pluggin the bypass is not a good idea and has no benefit, that's why I'd recomend a bypass filter.

60 psi isn't high pressure by any standard that I'm aware of. You don't need a HP4 ..it's the same crappy Fram inside ..and every oil filter out there can take (burst testing/rating) probably double what you're pushing for pressure.

Get the two quart size if you have the ground clearance for it ..as was suggested.

Typical automotive collapse rating is a minimum 100PSID.

Typrical burst..where the seam unravels or the gasket rolls out of the retaining ring is approximately 125-150PSI for automotive filters.

60 psi to a filter is nothing......

However the Mobil 1 filters easily exceed those ratings. It uses thicker metal shell and backplate and probably bursts around 250psi..

The AC PF2232 or it's aftermarket versions such as the Mobil 1 M1-303 or Baldwin B1441 might be another option..

They are designed for the Duramax diesel and have a high burst rating (can't remember the spec). Duramax Oil pressure in cold weather can be quite high.. Also has an internal bypass valve.

Beta specs are good too..

M1-303:
Nominal: 5 microns (Beta=2, 50%), Absolute: 18 microns (Beta=75, 98.7%).

B1441:
Nominal: 8 microns nominal, Absolute: 23 microns.

IIRC the last time I bought a case of B1441's from www.westfleet.com they were around $6 each.

Bill, I've never even heard of one of those... I'm gonna have to get one and try it out... thanks!

The gasket size is slightly different, but it still should work:

PF2232: O.D. = 3.48"/I.D. = 3.10"
PF35L: O.D. = 3.38"/I.D. = 3.04"
