Inliners International Forums General Discussion Hi Performance 292 oil pan and pump

I am building a 292 that should end up being around 300 HP.Will the stock 292 oil pump and pan work or do in need to upgrade.Its going in a 32 bantam altered and will be drag raced only.

If the Pan clears Everything USE it. The Stock Pump is also Fine

aa-fuel,
I run a 9-second 23T altered with an inline six and where you will have problems is on burn outs and on shut down. You will see your oil pressure drop to ZERO from the negative G's. The first time this is really disconcerting. I now have a trick racing pan and guess what - I still lose oil pressure after I go through the lights, so I just let the car coast down gradually and watch the oil pressure slowly drop to zero and then, when I am well under 100 MPH I just kill the engine and roll off the track before restart. Sometimes in the heat of competition I let the engine comtinue to run on zero oil pressure and so far there has been no damage to the bearings after hundreds of runs. I don't know if that would hold true for your 292 though.

Also, if you assume 2 G's off the starting line and do a force analysis diagram you will realize the surface of the oil in your pan is at a 60 degree angle to the ground, meaning the back half of your crank is completely anchored in frothing oil. This is where a good racing pan can help you. Because our oil pans are much longer than a V8 oil control is a much bigger issue.

So I guess I recommend a good racing pan, or at least deepening and baffeling your stock one. A stock pan may work - it just isn't going to be optimal. Good luck. Post pics of that bad boy.

Thanks French I never realy thought about How Light That Ride is and What The Gs would do to oil Pressure. And at the same token I never seen this issue on mine Or on Mikes Camaro and He is running the 292 pan on the 250 block. I may have to ask him about that.

Thanks Twisted and French for the info.Going to a deeper sump is not a option as the engine sits fairly low in the chassis,but something like a oval track pan with the sump made wider or the sump the full lenghth of the pan may work.Is there anyone besides Sissels that makes them.Thanks

hay;
I think that speedway sells a kit to modify your pan by adding to the bottom on the sides of the oil pan about 2 quarts worth. If I recall.

We just had Canton make us one for Leo's Turbo 292, w/ Hybrid Head.
They still have the templates, and blocks for fitting.
We will be posting pics soon.
