SBC stocker oil pans

[Dragsinger]

Soon I will need a SBC stocker oil pan. Let me know about some options.
Thanks

Not intending to hi-jack this particular thread but want to piggyback a question onto it. I have heard people talk about needing a removable plate on the oil pan to allow an inspection of the connecting rods?

Could someone be so kind as to describe where I need to put this access plate? Better yet be even nicer to see a picture of a pan with one. I've got my own ideas on how one should be built but would like to see one to confirm if my thinking is correct.

For Chevy applications, Moroso, Milodon, Kevko and Canton make stock appearing oil pan suitable for Stock Eliminator class. These pans have trap doors, baffles and scrapers built-in.

Last time we showed up at an NHRA race with an oil pan with a bead of weld on it we were told to NEVER bring it back. Never heard of a removable plate. If they want to see a rod, they want to hold a rod and piston in their hand, not lay on a creeper under the car and look through a hole in the pan.

This inspection plate is something we came up with the Top Stock cars running IHRA about 3 years ago!

Thanks for that input. Maybe that's (Topstock) where I heard it referenced. Didn't really want to hack up a pan. Just out of curiosity, how did you seal those pans? I just see this as a leak waiting to happen and at the wrong time.

The obvious choice for the best is a factory Corvette trapdoor pan, but it won't fit most K-members.
The old reliable Z-28 pan with the semi-circular windage tray is a favorite of mine, fits everything, and can be had at your local Chevrolet parts department, under $100 for everything the last time I bought one.

Dave,

Your comment about the early Z-28 pan is interesting. I "think" the "wrap around" windage tray is old school and my reason for thinking so is because no aftermarket pan builder uses that design.

The most common design I see is the screen type and louvered type, both designs are bolted in the pan, farther away from the crank than the Z-28 design. Again, I remember some years ago several test done that concluded, "the farther away you can get the oil from the crank, the better"

Of course, we began this post talking about stockers so the "horsepower" pans are not legal. However, my original intent of the post was maybe someone builds a screen or louvered style pan packaged in a stock appearing design.

Robert we machined a 2" hole in the side of it and made a plate of 1/4" Aluminum big enough to cover the hole and drilled a couple of mounting holes in it with matching holes in the pan. then Installed bolts thru from the inside and welded them to the pan, that way when using the inspection cover you don't have to worry about them backing out. As for sealing, i just used a good silicone between the pan and plate, no leaks!

Thanks Woodro. That's similar to what I was thinking of. Actually, IF, I did this, I was going to make a gasket to seal the plate. I was thinking welded nuts to the inside of the pan. From the sound of things, I won't need to do this after all.
