Project: Dads 1947 Chevy 3100 part 4

Despite having a full plate I managed to get up to my dads place a few weeks ago and got most of the engine back together for the Chevy truck.  In the last installment we cleaned up the pistons, inspected the rod bearings and got everything ready for reassembly.  My dad thought we would be lucky to get the pistons back in the bores -he was pleasantly surprised by how much got done.  I think I will fall back on working on old vehicles for a living if my business endeavors don’t pan out.

I was working along and realized I wasn’t taking any pictures so I got my iPhone out and took a few.  We used the same ring compressor I use on Alfa engines to install the pistons, the same Redline assembly lube on the bearings and the same can of WD40 to wet the rings.  Connecting rod caps and bolts are as expected.  The main worry here is that the little ‘scoops’ in the sheetmetal parts that go over the connecting rod caps are oriented correctly so the turning of the crank forces oil into the scoop.

There was a preferred orientation for the installation -BDC.  Couldn’t get my fingers around the connecting rod journal to orient the bolt if it was anywhere else.  Oil pan gasket is a 4 piece affair that’s a real PITA to install.

The little scoops on the connecting rod ends grab oil out of these troughs.  Oil is pumped into the troughs.  A weird system.  Later engines had the oil pump directly to the big ends.  Lots of people told me to go with the later engine but this is the original, and it did 50 years of uncomplaining service. 

Oil pan is held on my a bunch of slotted screws.  I scratched my head, shrugged, ignored the torque spec for these and just made them tight.  I think there was a picture of a torque screw driver in the manual??

Up soon: mounting the flywheel with new ring gear and the new clutch.  My dad finally renting his house in Gulfport MS out really changed his mood about spending money on this project.

Here’s the ‘new’ transmission.  Early Advanced 47 ‘s had a 4 speed w/granny first, floor shift, straight-cut gear transmission that was similar to the older model and similar to the later column shift model, but not the same as either -so it was a big deal finding this ‘box.  I’ll be on grit removal and clean up detail before long I suspect.

After we got the pistons all in and the big ends torqued, we took a break, had a pizza and some wine and were shooting the sh*t.  I had about an hour-and-a-half before I had to head home so I said ‘hey- lets put the head on it too!’.  20 minutes later we were doing the torque job on the head bolts.

Do they call this a long block?  I left instructions to install the tappets, push-rods and rocker assemblies before I came back up.  I’m due for a return, maybe next week.  Also would be nice to paint the engine with the can of original color engine paint we got.  

So I have managed to help us along to this point.  I think we have all the parts we need to complete the engine re-rebuild and installation.  My dad called me on Monday of this week to ask if there was a gear puller somewhere in my tool box -he was trying to get the U-joint yoke off the drive shaft to see if he could figure out why it was frozen.  Good to see he’s not waiting for me to do work on it!  I think we will shoot for a Spring 2012 debut.

  1. glad to see another entry in the log on Pop’s truck. I will be putting my v8 into my 53 chevy p/u this Sunday.

    Keep up the good work! Your Dad will be very glad to have his old friend back on the road next, I hope to do the same.

  2. Hi. Thanks for your column. Enjoyable though I doubt I’ll ever own an SS.
