I have a 1968 d200 with a 1970 318. It currently has the sp2p on it.

20 years ago, when it was put on, it was discovered that it had a crack that caused an oil leak (what I was told from the previous owner) and was fixed via epoxy. I have not seen nor investigated past that statement. He is a good friend of mine, so I’ll take his word.

The motor has 30k miles on a rebuild, but it is a grease ball. It was driven the 30k miles, then parked because the owner (my friends nephew) passed away from cancer. Maybe 5 years on that rebuild...

So I assume that the intake has been leaking the whole time it was driven.

I have a performer intake that I “could” borrow from a spare motor.

Between the 2 intakes, which one is more favorable? I’m not going all out power, just a nice cruiser, and Home Depot duty. I would like more fuel mileage if anything. I’ll be running a 600 cfm carb on either intake.

So... fix sp2p or swap performer?
