Stuffing the 383 back in the valiant while i assemble parts for a gen3 swap. Will i be ok with the stock pan and a windage tray for the 7-8 events the car might see this season or am i better off biting the bullet on a moroso rr pan. Thanks!

I think ok for autox. Short amount of time, short one direction then immediately short other direction.

It’s the long continuous corners that really suck the pan.

This! watch your mechanical oil pressure gauge in a lonnnng corner and you'll see it drop.
See if you can find a used accusump.

In our experience, completely inadequate. We had the spun rod bearings to prove it. We have a Milodon road race pan on the shelf for if/when my son every builds the car again...

I've braked a stock car hard enough to drop the oil pressure to the point that the warning light flickers.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Same here on my '73 Dart. With a mechanical gauge you can actually see the oil pressure go away under hard braking.

For its next engine I added a baffle going round the deep part of the pan to keep some oil there.
I don't have a hard braking oil-pressure drops anymore now.

Hope to get the car on a circuit in a few months to see how it controls the oil during higher speeds and cornering.
I have my doubts on the side where the gap is for the oil-tube. That might still leak enough oil 'up' to cause issues on a long corner perhaps.

I didn't get a chance to look at the gauge but the light caught my eye. Your solution is essentially what I did as well.

Depends on where you are running, your tires, and to some degree how smooth you are. I'd baffle the pan.

You can make some baffles that should help. Unlike the small block you shouldn't have to compromise the baffle for the pickup tube.

Goals of your baffles are to
deflect sloshing,
retain a higher level around the pickup during extended g periods,
make sure the oil can drain back to the sump.

All depends on how fast the car is. The stock pan will work with stock tires. Once you upgrade the tires and suspension you need to upgrade the pan. Once you move to racing slicks you need to get really serious with the oil system. The vehicle is a system.

The windage tray by itself is NOT good enough when you're concerned about g-force oil control from cornering, acceleration and deceleration.

I've run a baffled pan for my SB like pictured from Bigblockmopar (above)... this was the single best engine mod I've ever done for the car for autocrossing (pylon and hi-speed)... too bad MaMopar didn't make the pans like this in the first place. Without the oil control provided from the welded in baffles, the oil pressure always would drop low.. and the lifters would click.... no doubt bearings would eventually wipe out and self-destruct. WITH the baffled pan, all of that went away... ran the car seriously in national SCCA Solo competition since the late 1970s... BEST modification ever!

Now, I'm building another SB engine and will install the Milodon road race pan.

I also have a 3-quart Accusump setup ... never yet installed it, maybe not (all still new).. as it adds weight. BUT, some serious road racers I know highly recommend that extra setup for additional insurance, and with a red illuminating light that turns on when it becomes activated, they say it does its job under serious g-force loads (and being a pre-oiler for start-ups after long periods of sitting time).

For Big Blocks, I think the least type of oil pan would be the 440-six-pack/Hemi pan that has the front/rear weld factory baffles (if I'm correct about that factory design). At least with those baffles, they will help from oil starvation during acceleration and deceleration, and probably some for cornering.

Best bet today.... highly consider something like the Milodon road race pans.

If you are going to be cornering hard then you'll also need to baffle the valve covers so you aren't puking out of them and update the dipstick with a good seal. You'll also probably need to baffle the rear axle and/or move the vent up. Might need to so something with the gas tank too. Everything starts to leak when you corner hard and it sucks to get black flagged and put on the trailer after spending a bunch of time and money getting to the event.
