I need some input on my engines oil routing, i have this panshovel engine, fresh rebuild with House of horsepower Panhead style cases. the thing is that the internal oil feed is different from stock cases, same as 70 up i think.
I am using hydraulic lifters and top end oiling routed from my knuckle cam cover, both are fed through the same high pressure feed (hole). Im also using a S&S casted aluminium oilpump stock 70s style.

Cant find anything really useful in the S&S manual since they only cover stock cases and HH are long gone but this forum is full of wizards that might have tried this.

I guess my main concerne is about the lifters not getting enough pressure with this setup.

As long as your lifter blocks are still open to allow oil to get to the lifters you shouldn't have any problems....

thank you again, its always good to get a second opinion.

This is the actual motor, my first harley engine rebuild so i need to research everything.

as seen in pictures these cases can also be set up with shovelhead type head oiling but i like the knuckle style.

thank you sir, i found this picture on a set of similar cases just to make it clear how they are machined.

The green oval is where the high pressure feed goes.
Red X is not drilled on my case.
Yellow X is plugged (pressure relieve, exess oil)

Otherwise the same as mine.
