Everyone ready for another round of Picapalooza?
Even with all the other ongoing projects (and a newly found health issue...woo hoo), I'm still slowly pursuing the Motorcraft 2150 swap. I knew I had one but I couldn't remember exactly where. I tore the shop apart looking for it with no luck. Then I thought to myself; "I wonder if I threw it away?". Sometimes I get tired of dealing with the mess and snap..at which point things go into the scrap barrels that maybe shouldn't LOL. So I went out to the scrap barrel, dug my way down to the bottom,....and sure enough, there was the 2150..where it had been for about the last 3 years.
I'm currently searching for a Holley 2300 that may have suffered the same fate
And here's the test subject in all it's beauty. I guess it looks pretty good considering it's been stored outside at the bottom of a barrel for a few years.
I gave it a good cleaning with Power Dissolver but that didn't really help much. It works great for dirt, grease, and grime....but not so much with oxidation. So I knew I was going to have to do this one the hard way and with some more aggressive chemicals. I wasn't originally going to give it the full "treatment" (cleaning, deflashing, polishing, etc) but once I got to working on it I realized that it really needed some TLC....plus I have a problem with leaving "well enough" alone.
First I had to do battle with my old arch nemesis casting flash. I REALLY HATE casting flash on anything. It looks terrible and it always has a knack for biting you when trying to work in tight areas. It's almost as annoying as Photobucket
I started with the top cover and removed all the flash from the outside areas.
Then I moved on to a more important spot, the air horn. As you can see, mass production doesn't make for smooth finishes. The flash and high spots are easy, but voids just have to be glossed over or you end up digging a hole while trying to "chase" them out.
After the first pass with carbide bits.
Second pass with 220 grit.
3rd pass with 320 grit.
4th pass with Scotchbrite roll and some contrast for reflection
I could have left it like this, but I like to do my stuff where you have to look closely for the mod. I like for people to look at my stuff and wonder if it's been modified or if it came from the factory that way.
So with that in mind I dropped the top plate into some aluminum cleaner I use that contains HF acid. You can buy it off the shelf but it's kind of nasty stuff so you definitely want to wear the proper PPE when handling it. I like it because it cleans great and balances the color.
After about 5 minutes it comes out like this.
Then after it dries you get this.
You could leave it like the above pics if you wanted the ROS (rebuilt old stock) look [hint hint class racing guys ] but I knew if I did a quick once over with a small brush I could really make it shine.
All brushed up and shiny
Here's a shot of some of the linkages and small parts after coming out of the rust dissolver bath. Stuff that needs a little extra attention goes into the jar of green stuff on the left
After I finished the top I started on the boosters. This is pretty much where I am now.
