Re: [Amc-list] Response to Oiling Problems and lifters

[Wrambler242@xxxxxxxxxxx]

That's what I thought too.
 I've always thought the Dodge 360 lifters where an interchange.
I'm wondering if they misspackaged a set of 273 non oil feed lifters?
You would think that if the lfiters are wrong someone would own up to it?
was the possibilty of wrong lifters pursued with Summit?
I've had that happen twice ot me recently.
A GM power window switch in a sealed box from Rockauto and an incorrect "new" master cylinder with no signs of it being in and out of the box. If packaging gets out of synch at the plant the wrong crap goes in the box!
