Why is the modern consensus to skip the external oil line?
Just wondering.

>> 1. If you have a roller cam, you need to make sure the oil port doesn't

>>
>> 2. I like the Moroso restrictors, but I don't think they are mandatory.
>>
>> 3. A proper baffled pan is a requirement.
>>
>> 4. I like the front to back oiling line, but I don't consider it mandatory.
>>
>> 5. I did a mod described on the network54 forum where you put a restrictor
>> in the #1 cam journal by tapping from the cam down. You put a plug in the
>> crank journal side. I can't describe it here. There's a picture that helps
>> a lot. This mod is not required.
>>
>> 6. Install the cam bearing as far forward as possible. Installing it far
>> forward keeps it from leaking a lot of pressure onto the cam gear. This mod
>> is not required.
>>
>> 7. There is a mod where you drill a hole in a plug to provide a steady
>> stream of oil onto the distributor gear. I did not do this mod, but I think
>> it is a good one.
>>
>> 8. Some people use grooved bearings for top and bottom on the crank or
>> something like that. It is supposed to help.
>>
>> 9. Some bush the lifter bores. This is probably worthwhile, especially if
>> you have a roller cam. I don't consider it mandatory, though.
>>
>> So, the only mod that is really required is a proper baffled pan - in my
>> opinion.
