Do the sandcast models have "wrinkle tanks", too?
I saw the 5/70 tag on the vin, that could actually be a 70 or 71?
My 550 was manufactured in 73 and is titled as a 75.
I'm new to the whole sandcast thing as well. I know it was the technique used to cast the motor, but other than that fact and that they sell for insane amounts of money, I am clueless too.
BTW I bought a 1985 sandcast a few weeks back, 6600 original miles, pretty mint condition, can I get 30K?
