Diaper or Catch Pan For Early B-Body

Whats the preference here? Diaper or Catch pan for my 64? Pictures would be great! Thanks!! Ted

Ted.. there is no best answer here.. its what will
work easiest for you.. they both will do the same
job if done right.. on my junk the pan is easier..
and smooths out the air flow under the car... for
others the diapers are easier but make sure you get
one that wont burn in high temp areas and no plastic
strap connections.. I remember one that Hemi Fred had
that has plastic parts that didnt last

I've had the same plastic buckles on mine going on three years now... no probs (100+ passes last year alone so it's been in the field being used). location, location, location that said I went with a diaper, but I also had the car modified to allow the easy use of such products.

Ted give Glen (Wyoming) a shout. Believe he has a blanket and runs an older B with a big block like yourself.

Hey Ted get DVW (Doug) to post some pictures of his diaper. VERY NICE!!!!!!!!!!!

The reason the pan would have worked best for my
W-9 engine was that it was a dry sump engine so the
pump and lines would clear much easier with a pan and
it wouldnt have a expiration date like some of the
diapers and it would help smooth out ail flow under
the car.. but now that engine is sold and I can go
with what ever I want and that MIGHT be a pan again

I made a drawing of my pan and sent it to Rustler. Fit near perfect. Going on its 5th year.

Doug.. how many degrees of temp does that hold in it

Where's the like button? Very nice!

For the guys running alcohol a diaper is a win win.

Thanks guys! That Russler looks like a great fit!

It has a heck of a time getting oil temp above 150 before a run. never seen it over 180' I actually have thought about a pan heater.

Nice to hear you liked Russ's work Doug. I'll show him the picture. He's a great guy, and an old nostalgia racer himself.

I have the Rusler also. Fits great, but on a filled block I had to add an oil cooler to keep mine cool on street drives.

Fits great, and does a nice job for sure though.

Pan on my 64 hemi car

Looks good, might do one on my 64, how deep is your oil pan? Is there any absorbent material in the box? Aluminum or steel? How high up or deep is it, hard to tell from pic? For the rest of you guys, which one would contain the oil better, flying parts not the problem. And Mr P, why would you need a diaper for a dry sump? Granted you'll lose some but not the gully washer of a 8-10 quart pan.

I didnt want a diaper I wanted to build pan
and to my understanding I was told that even
the pump was to be with in the diaper if you
went that way

My pan is a 10qt charlies pan. I think its around 10 inch's deep. My Kframe is cut and boxed square. The object was to get the catch pan to fit tightly around the K frame opening. Thus the K frame would also act as part of the pan, and runoff from the k frame would go into the pan. It is powder coated aluminum. the pan sits less than 1/2 inch lower then the pan so there is room for absorbant material. I put a few layers of absorbant material in it and used speed tape to tape it down.

whats the rear of the pan bolted to I see the front is bolted to the K member any rear pics
thanks Tom

Do you have any thoughts on closing the sides of the K member to direct oil to the sump?

For the rear we used an aluminum plate bolted to the transmission, in place of the torque converter inspection plate/cover that hangs down the depth of the pan. The plate has mounting provisions that the rear of the belly pan bolted up to.

I have thought about doing that. The NHRA rule book for belly pans states something along the lines of the pan covering from frame rail to frame rail. Easy in a chassis car or dragster, not possible in a stock front suspension. I think closing off the K frame on the sides could bring it more in-line the rule, and the argument could be made that by utilizing the k frame and oil catch pan in this manner meets the intent of the frame rail to frame coverage. Might end up making block off plates at some point, especially if I raced regularly. I'm more interested in have a street car lately. I know a few people with similar setups that race regularly and never had an issue with tech. Its all about doing the best you can, no setup diaper or pan is perfect when dealing with stock suspension mopar with a steering link going through the pan.

Thank you for the reply,Ya do what you can and adjust along the way.

That looks very good! Nice work!

I just cut the "k" and set back the engine some.I really dig your vision and will follow in your footsteps!! Thanks for posting that

Put a radius at the end of those cuts so it doesnt
crack

Been thinking about this all afteroon I really like that belly pan that fits in the notched "k".But the diaper also cover the sides of the block.If something blows hard enough to go through the oil pan it will go through that pan also,,,,,,,,

Maybe some Kevlar sheets glued to that pan

I wonder if a stamped side engine cover can be used on both sides.

Not to hi-jack but DRW, is that an Aerospace mandrel for your alt and vacuum pump? I noticed you have a spacer holding it away from the crank trigger wheel. I am wondering how to do mine without having everything all bolted together as one unit. Jim.
