Gary, I agree with Frank. It looks like vinyl or nylon high pressure hose and definitely has high pressure ends on it. The thing I would be more concerned with using it is how high off of the valley it sits. I doubt you would be able to use an intake like an Airgap without changing it. We run a 90 degree AN fitting with stainless steel braided line to hug the block without restricting oil flow. You could always change it once you got it home as that would not stop me from buying it. The part that does concern me slightly is the deck surface on the one side looks to have some rust that has pitted into the surface from the cylinder to the outer section of the block. If what I can see from the pictures it correct, you will most likely need to surface the block to get a proper seal especially if the compression is up around what he states. Second concern would be the compression without the extra head bolts or an O-ring. At 11:1, you are questionable, at 12:1 I wouldn't run it without one or both. Judging by what I can see, I would look at this engine as you are going to need to take it apart to make sure of what you have. If you are getting enough with it to make it a deal you can live with, buy it. Get it home, disassemble the engine and clean everything. Inspect the parts and check all your clearances. Calculate the compression and make the modifications to the block if needed before you re-assemble it. If that rust on the deck surface is there, have your machine shop surface the deck first. This way you know you will have a good engine that is not going to give you trouble.

The hose itself should have some writing about what temp range it's good for on it. It should be fine up to around 300 degrees, which is more than enough. -- Frank Swygert Publisher, "American Independent Magazine" (AIM) For all AMC enthusiasts http://farna.home.att.net/AIM.html (free download available!) -------------- Original message ---------------------- Subject: Oil line modification Date: Fri, 18 Feb 2005 09:17:32 -0500 I am contemplating buying this 390 for my SC/Rambler and have a question about the oil line modification. When looking at the picture of the modification, it sure looks like it is made of a garden hose type material. Would this hold up to the heat of the engine. I have tried to email the seller but no response yet. This would be a great pickup for me as my family and I are going out to Vegas in April and I can crate it myself and get it shipped back to the east coast. Thanks in advance. Gary N CT
