Not original motor in that truck...'77 offered the 351M and 400M in lieu of the 360/390 from previous years.

I know because I own a '77.

I know....splitting hairs.

In my Z I just use Mobil 1 oil and filters.

It might have been older then. I remember it being a 360. And being a rust bucket. The inner front fender wells. Rusted out in no time.

Any of these are good:

Fram Ultra Synthetic
Mobil1
K&N

I love k&n due to the hex head on the top to easily get it off it'll its glued on from seal

Many of these brands are made by the same company.

For easy to find, low price and quality, NAPA Gold. Same as Wix.

amsoil.. someone had to say it.
now you have another choice.

Now that we seem to have that worked out, it’s time for the important question...

What kind of oil are you going to use? :stirthepot:

Its made by the same company that makes Mobil1.

Oil brand discussion is like virus. It causes a lock down.

I use Amsoil oil and filters in the Z. Everything else gets Mobil 1. Probably overkill using amsoil for the Z but I drive the car 2-4k a year and change it once a year so dont mind spending the extra cash. Most filter companies share media these days and make filters for each other so as Askmea? said they are probably made by the same company. I would just stick with wix, puralator etc.

I don't know about the relevance of who makes them, but the Amsoil and Mobil 1 filters are not the same.

This thread... :facepalm:

:iagree:
I would post my cat pic. But I'm on my phone.

I.B.T.L.

I'm only amsoil for oil. Best in the biz.
