Re: Oil Filter Lines

I think JD my have had the answer--at least sounds logical.

The earlier engines had mechanical lifters & no extra oil return hole so not too many options other than full flow. The 356 with hydraulics was a different casting-different setup.

In 51 on they made the changes to use essentially the same block for all engines & lifters--so added the extra hole to make them all partial flow. Maybe some of old kits still around with old instructions, or more likely, old time mechanics still did way they always had without reading instructions.

Still don't understand Big Kevs original filter with the reversed stamping on ports.
