Oil Pick Up Tube

[dfrazz]

Swapping out an oil pan and tube on a 1977 440 and having a trouble with the correct oil pick up tube. I had a Moroso deep pan and I’m installing a 440/Hemi pan with a Melling 63-S3 which should be correct. However, the thread size on the old pick up is considerably larger. Does anyone know if a ‘77 440 block has a larger thread hole than a ‘68-73? Or did a PO modify the hole?

Basically, wedges use a 3/8" pick up and Hemi's use a 1/2" pickup.

If the PO modified yours to 1/2" pickup that's good for you. Just buy a Hemi pickup for your new pan.

The new pick up I bought and in the picture is 3/8" which is why I'm not sure if this block has been modified or a '77 block takes a different thread size.

Yes, the previous owner installed a larger diameter pickup tube. You're looking at the difference in your left hand and can see the difference. The Melling 63-S3 is an OEM replacement that is 3/8"NPT (approx. tube diameter 1/2") and if you measure the large tube end of the Moroso tube, you will find it to be about 3/4" diameter for a 1/2"NPT pickup. By changing back to a 440/hemi oil pan from whatever source will hopefully require a Hemi pickup which came originally 1/2"NPT. Mancini Racing has a selection of 1/2" pickup tube, but the correct tube will depend on the pan depth. Melling does not support 1/2"NPT pickup tubes.

All 350/361/413/383/400/440's came with 3/8", doesn't matter what year. All 426 Hemi's came with 1/2". You are better off with 1/2". Enjoy.

He modified the pickup at the block. What (whos) pan are you trying to fit up? If its a moroso or milodon, theyll have an exact pickup to match in 1/2" for your chosen pan.

Thank you. The Hemi/440 pan is only 5" deep.

I'm swapping to a 6 qt Hemi/440 pan MRE - Oil Pan & Pick Up, 6 qt.

If you can weld, everything you need to make this work is in your hand in post #1. Otherwise, Mancini should have an exact fit for you, and may be the better economic choice if you sell all the leftovers you arent going to use for this build.

It is best to get them in a package deal to ensure they match. Just make sure you select the 1/2"NPT pickup tube as they also sell a 3/8"NPT tube for a block that hasn't been drilled & tapped for the larger tube.
