Made a little more progress.

Front fuel lines are roughed in. Wound up running a new 3/8" return line with a flare fitting.

Accessory drive slapped onto the new engine, just about ready to drop in now.

Needed to do a little minor trimming on the valve covers to clear the alternator. But everything fits up pretty good. Alternator is a little closer than I would like to the driver side manifold, will see what I can do to shield some of the heat as I suspect it might get pretty toasty in this space.

Now I need to scout for a trans jack I can borrow to roll the trans into position and get the motor dropped in.

Had a feeling this project was going too smooth.



2 of these (15 year old) mcguard wheel locks stripped/cammed out on me. Chiseling them off was no Bueno. They have the hardness of used chewing gum, so will try my luck with an "emergency removal socket" deal to try and break them free. Worst case I can weld the "key" to the worst one and try to get it off that way, since there are two I am kind of in a precarious spot. Sigh....

Needed to pull out the universal locksmith tool, made quick work and didn't roach my wheels too bad. Done with the wheel lock things, they suck! lol

Just going over some notes before I roll the trans into place. My goal with the 4L80e swap is to rig up the stock shift linkage. Y'all 4L80e swap guys feel free to school me - I know some of the later burbs came stock with a 4L80 or 400 so should not be too lofty of a goal. Apparently I need to move the link rod/arm pivot back a couple inches on the frame, and lengthen the shifter rod from the column an extra 2". I think it will all bolt up? Guess we will soon find out.


The selector deal bolts up to the shaft fine.

A while back I picked up one of them $30 chinesium shifter rod setups - just in the event my fabrication skills fail me. Tossed the funky switch that came on the trans core when I got it, as the column holds the neutral safety and backup light switches. So just three connectors and the shifter/cooler to address. I need remember to slap the trans temp sensor in the pan before I fill it too.

Should have the new aluminum driveshaft core today to prep it for a tuneup and shortening at the driveline shop. Slowly getting there.
