    Took a few minutes today to start trimming the bungs in the ports. One side is trimmed. The air grinder and carbide cutter make fairly quick work of it. A sand roll in the Dremel will be used to finish it up.

    Believe it or not, mounting it with the motor plate has been on my radar. It *might* happen, but it sure complicates the FEAD. Particularly since I hoped to use the efi 460 brackets for the alternator and power steering pump. The latest train of thought is to build a bracket that attaches to the front of the head and then is supported in the rear by an exhaust manifold bolt (or 2). Or even the main engine mount bolt

    Somewhere recently I saw a large turbo mounted “engine plate” style. It was centered and up somewhat, and the actual engine was motor plate mounted as well. Looked pretty good.

    60# would justify something along those lines for sure, lol.

    Keep on truckin!

    lordy, that's a fair bit bigger than I thought it was! Dang sure bigger than the one I got a while back which I was thinking was too small (was for an 11 liter diesel, not sure what I was thinking). Bed frame angle iron!

    This is about where the turbo will sit. It weights about 60lbs, so it is going to require a sturdy mount!

    Looks like I can use the stock fuel tank straps to mount the fuel cell.

    Being the DIY guy I am, I went ahead and used JBWeld to seal up the bungs. I mixed it up, pulled out a bung, coated the bottom portion, slid it back in, twisted and wiggled it, then installed the set screw. Might have got a little much on them, but I'd rather it be too thick than too thin. Besides, I'm not out to win any beauty contests with this thing. When I checked on them this morning, it seems as if they are solidly fixed and sealed. I feel much better about these than the one's I did for the original Ranger big block project.

    Nice progress! I need to arrange a few binges for my truck project.

    GB2018/19 is officially over. 98% of my goals were accomplished, but I purposely set them high. The things I didn't do were just a couple of minor things, so no biggie.

    New Year's Eve was spent mostly cleaning parts and assembling the engine. I tapped the front cover for a turbo return line and tapped the throttle body for pipe thread because the fitting was loose.

    New Year's Day started with painting the engine and cleaning the Crown Vic xmember because the efi460 was a leaker.

    While waiting for everything to dry, I worked on the intake manifold.

    I considered many options for attaching the bungs and finally decided to tap them for set screws. The last intake I converted to efi (for the original BBR truck) had JBWelded bungs and it worked ok, but I was always concerned that they might come loose and cause a vacuum leak. The set screws create a mechanical connection and will allow me to have them welded or use JBWeld to basically just seal them up. The set screws I purchased were too long. Final screws will be shorter and the bung protrusion will be mostly trimmed away inside the port.

    A quick mock up of the engine and then the engine and trans were mated and installed. Input shaft is in this time! ( I left it out of this trans once upon a time....)

    Those are the highlights. Many many small things were fixed/corrected that did not warrant pics. Overall though, it was a very successful GB!

    Here's your update! Shop temp was good. Our section is not heated (never had gas turned on), but the surrounding sections of the building are, so it stays nice.

    Got to the shop at 12:30pm and stayed until 12 am with a brief run to Braum's for some tasty food.

    Soaking the heads in Purple Power worked awesome. I pulled them out and pressure washed them and they look fantastic. I dried them and later lapped the valves and assembled the heads. They are now ready to install.

    Engine and trans came out fairly easily. I amazingly avoided testing the tensile strength of the dipstick tube, wiring or any other easily missed attachments. Since I am using the efi motor front dress, I had hopes of reusing the efi motor's water pump, but it was pretty rusty inside. So I decided to pass.

    After the engine was out, I pulled the manifolds to compare them to the old manifolds. Outlets are identical at 2.25".

    Removing the fuel system was the part I was dreading the most. Gas always seems to run out of the most unexpected places. I managed to siphon most of the fuel out of the tank. The stock tank was a huge pain in the butt to get out, but it is done. In place of all this will be a 20 gallon fuel cell, the A1000, and -8AN hoses.

    There is still a lot to do, but I made more progress yesterday than I expected. Hoping to have the fuel lines run, the A1000 mounted, the engine together, mated to the trans and in the chassis by the end of GB2018/19.

    I need a garage binge. Mine will start as garage cringe though. I spotted a '67 beetle in there the other day... just the mirror. How did the heads turn out? It's Monday... how about you let me know by 8:30? haha. Guess I'm used to Monday updates. Enjoy the binge! I'm guessing that garage is heated or you will be chipping ice out of the ports today? 10 degrees? Well, maybe it's not windy. Pfffft.

    Happy New Year to you and yours James!

    Ebay had a 15% code active today so I ordered a 20 gallon aluminum fuel cell and a 31" x 13" x 3" intercooler. Can't wait for Garage Binge 2018/19 because I have a lot of stuff to do!

    Soaking the heads in Purple Power. Looks like it is working good so far.
