Thanx Truckernix. I'd be very curious to see that, because I think I may have a major problem now. I thought I had merely disconnected the plumbing on the side of the block and simply needed to replumb it. Now it seems as though I might have broken that tubing when I pulled it out, and will have to tear something else down to replace it. Do you or someone else know how difficult this process might be. Also, is it plumbed the same way on all 216's? The box on the side of the block and the routing of the tubing on 46 block I pulled out of the truck looks considerably different than the 39 block I put back in. Am I as hosed as it sounds like I may be? Please please say it isn't so...
