If you have mechanical drawings I could get from you it would save me from re inventing the wheel . I plan to use an oversize pickup tube on the 512 I am building now. The Heads (Boogieman ) and the block are at the machine shop (Mike Lewis Racing) for corrective machining. I will give a blow by blow in my other post as soon as i get the stuff back. I will say this , the machine work on the heads as received was very disappointing.

Leave the short section of factory tubing on engine block side for factory o-ring. Allen bolts required to clear 1" o.d. .875 i.d. tubing.

Hey 5one9. Is the bronze insert going to work with your counterbore modification? Im not sure what you counterbored. The factory oil tube flange or the engine block. Good Luck with the project.
The counterbore is for the pickup to press into. Your o-ring groove/bronze bushing are on the other side toward the block

I had the picture of you holding the new flange and now I cant find it. My postings are scattered across this site. Maybe you can send another picture to this series of postings.

You're right. scattered all over. If my computer wasn't messed up right now I would just print everything. But I'm having a hard time finding it too.

I recessed the pickup side to be a little better than just butt welding it. 99602367-292E-478C-8849-6A8AFD1010C0.jpeg 700B21D8-2036-4305-999A-890C3AA3F36E.jpeg 603CC1E0-605A-44CF-96DE-592B15275F22.jpeg E09E95E5-383C-4378-BDC1-1AD355D54080.jpeg

Very good. Innovate. Looks like you had made a flange yourself.Take a pump gear on a pump drive shaft and look at thar sharp turn the oil flow has to a make to get into that gear. I contour that area. The gears pull oil along the body of the pump. Looking at the oil pump interface on block the gear closest to the pan rali spins counter clockwise.

Heres a picture of oil pump gear center drilled for lubrication. Its a high performance modification. Both gears Both sides

Notice on your engine block where the gear has eroded the material where the driven gear spins. Thats from oil being squeezed out of that area. The centerdrilled holes contain oil to lubricate that area.

On that oil pump gear modification, look at oil pump mods on internet. Lots of other brands have/had oil flow problems when building jump up engines.
