I haven't posted anything in awhile but I'm still working on some things. I started working on the engine last month. I think I mentioned earlier that the short block is a MP piece I bought back in 2000. The short blocks were made from reconditioned non Magnum roller blocks. It's the 10 to 1 compression version. I believe there was also a 9 to 1 version. The engine has been sitting since 2004 or 2005. I previously ran a Weiand X-cellerator single plane intake on the engine. Last fall I bought an Edelbrock RPM Air-Gap for it. I pulled the Weiand and started mocking up the intake and carb but ran into an issue. The secondaries on the carb would hit the intake. It looked like the intake was cast wrong. After talking with tech support a few times, they had me send the intake in for them to look at. They ended up sending me a new intake but by that time it was the middle of winter and I had moved on to other things. Last month I moved the engine over to my place. I pulled the plastic off the engine and found a mouse next in the valley. The nest was made from grass clippings so I knew it hadn't been there long. It wasn't there last fall when I was test fitting the new intake. I vacuumed up the nest and put the engine on the stand. I pulled the heads, water pump and front cover. I didn't want to spin the engine on the stand incase there was crap in the pan. I pulled the pan with the engine upright and removed the windage tray. Sure enough, there were some grass clippings and mouse foot prints on the tray. There wasn't much of anything in the pan though. I think I got lucky and caught it early. Other then the nest, the engine looked really good inside. Everything still looked clean without any rust from sitting. Then came the task of cleaning up the block. There were a couple layers of orange paint and layers of dirt, saw dust and oil to remove. What a nasty, crappy job that was. I think it took at least four cleanings to get everything off. Even after wearing gloves and goggles, some paint stripper would end up on my skin and start burning. I'm glad that job is over! I installed the timing cover and put a new water pump on. Then I primed the everything. After that I moved on to the oil pan. The pan that was on the engine had seen better days. The sides were heavily pitted and would have taken a lot of work to refinish. A friend of mine had a 360 pan he wasn't using so he donated it to the cause. I saw and old Car Craft article on making a baffle for the stock oil pan. It didn't look too difficult so I thought I'd give it a try. I made a template out of card board and taped it onto the pan. I test fit it a few times onto the engine to make sure it cleared the pickup tube, then I transferred the template to a piece of metal. I taped the metal baffle to the pan and test fit again. So far so good. I had clearance around the pickup tube and nothing was hitting. I soaked the baffle in EvapoRust and then added some drain back slots. Here is the baffle welded in place. It works really good on deceleration but doesn't seem to do much on acceleration. I could have gotten the clearances tighter to the pickup tube if I would have had a bare block to test fit it on. I would have been able to look down through an empty cylinder and see how close it came to hitting. The pan isn't installed yet so I guess I could still add some metal around the back if I found someone local with a bare block I could borrow. That's all the progress I have on the engine right now. I need to take the heads in and have them looked at. They only have a few hundred miles on them but I did the valve job and guides when I was in school. I want someone to double check my work so I don't have any issues down the road. I also need to get the intake surface of the heads milled down a little so the intake sits a little lower on the engine. I could barely get the intake bolts started when I was test fitting things.

I don't know if anyone is following this or not but here's a small update. After waiting more than three months, the fasteners finally came back from the platers. I had then done at a local shop but the color turned out wrong. They came through with a yellow tint. I sent them to another place to get coated the correct silver color. This past week I dropped off the cylinder heads at the machine shop to be checked over. I'm also having some material removed from the intake surface of the head because I could barely get the intake bolts started. The intake needs to sit down a little bit lower. Since the fasteners came back, I was able to mount the LCA/strut rods to the K-member. I also temporarily put the 2" drop spindles in place. I got some work done on the aluminum pedal covers. I did some sanding on the gas pedal cover and mounted it to the original pedal to see what it would look like. Right now you can see the plastic gas pedal through the holes in the cover. I'm going to paint a thin piece of aluminum and put it between the pedal and the cover so it doesn't look cheap. I also got the brake pedal cover made. I was able to put a curve in the aluminum so it matched the curve in the brake pedal arm. I think there needs to be some more grip on the pedal so my foot doesn't slide while applying the brakes. My plan is to put some 1/2" rubber pieces in the holes. The rubber will stick up maybe 1/8" from the surface of the cover. That should give me the grip I need and not change the look of the cover. I think they are turning out good so far. The best part is I only have a few dollars in the attaching screws. The rest was free.

I didn't do much work on the car over the winter. Now that the weather is warming up, I've gotten some things done. If you remember, I'm adding engine compartment braces to the Dart. I made some aluminum brackets in order to attach the braces to the factory pinch weld. I sprayed the brackets with a matte clear but wasn't happy with them. I stripped the clear coat and decided to polish them instead. I test fit them with some nuts on the bottom side of the pinch weld. The nuts were more visible then I thought they'd be and they looked cheap. I ended up making another bracket to go on the bottom side. The lower brackets are threaded. Basically, the pinch weld will be sandwiched between the two aluminum brackets. I think this looks much nicer. I'm going to use some polished button head bolts to attach them to the car. I liked how the gas/brake pedals turned out but I wanted something that would give me some traction. Plain aluminum might get slick in certain conditions and not be the safest on the street. My father-in-law cuts up old tires and uses them for traction around the yard during the winter. That gave me an idea. I used an old socket(with the edge ground to a sharp point)to punch holes in an old tire sidewall. The rubber plugs it created will go inside the holes of the pedals.(rubber will stick up higher then the aluminum)
