Dave,
for 'pure enjoyment' of your car, your plan is best...
but you're going to enjoy driving it so much, you'd better build up your gasoline fund..
Block is 4 days after mine. Mine has an unusual date cast of a109. It's a 661 also. My off-road am has the 141 stamp also
There's no VIN stamp on the machined top of the block? but by that date *(March 11)... might there be one on the cast surface above the oil filter? THOSE are extremely difficult to see presence of, much less to read...
Not sure about the raw aluminum, but the early covers aren't supposed to be shiney like the new ones GM sells. So far there are several different methods used to finish them. One member here, LYNN was telling me he used a certain paint and then put them in the oven at 400 degrees.
Yeah. I'm a Harley addict too. Mine is an 81 FXS Lowrider 1340 with the all black wrinkle finish engine. Lowered 2 inches on the swing arm, 5 gal fatbobs, has the over and under speedo and tach dash and gauges on the tank, duck tail fender, wide glide forward controls, but still use the narrowglide front end with wide glide handlebars for the narrow front . It's all black front to back. I call it Black Bart. It's getting to my knees though its so low., but it's fun to drive. I love the 4 speed's and you can't beat that shovelhead sound. I did a retrofit 91 softail CV carb and woke it right up. The original Kehein was sloppy as heck. Better throttle responce as well.
Hi Dave. It's a process things like aluminum intakes, distributor housings and the Z28 valve covers are put through to restore the original dull like finish. Not exactly sure of what is done, but I have heard there is a tumbler of sorts involved. I'm curious myself. I have a set of non drippers I want to get done soon.
