Cuda_Al's Copper 1967 Barracuda Fastback
Day 4
The new timing chain arrived and was installed, perfect tension. Happy with the timing chain the work moved to the heads, my builder chose to go with new springs, retainers and locks, the machine shop used the originals. One by one the parts were replaced, pretty easy with two people. While at it the heads were blown out to clean all the machining dust. The day was wrapped up with fitting all the rings on the pistons, he chose to use a current chart for clocking the rings from what is in the service manual.
Day 5
New day, one by one the pistons were coated inside with oil to get the wrist pins and then oil was liberally poured over the outside and worked into the rings. As each piston was done it was inserted and bolted in, torque would be done later. Each bank was done separately, 1 - 3 - 5 - 7 then 2 - 4 - 6 - 8 to keep from having to rotate the engine back and forth. Sections of tubing were used to guide the rods in and protect the crank from being scared.
Once all the pistons were in the assembly was rotated once again this time to facilitate torquing each of the nuts. Afterwards each of the rods were checked at the crank for binding. Still time available a new high volume oil pump and pickup were installed followed with the windage tray. We needed to play with the shape of the windage tray to get it to clear the oil pan (Blue Loctite was used on the windage tray bolts).
That done we wrapped it up for the day, literally. A trash bag is put over it and tied closed. Another thing of note was the use of extra washers on the balancer bolt to lessen the stress on the threads (although this is a spare bolt).
