Darren, For sure you the 409 casting......but honestly, when there was brief discussion at
www.nastyz28 on the casting dates, we never came to a conclusion. On the above example you might assume that the "202" is a julian date...but then we/I didnt know what the D 21 was.....and I never continued researching M.C. castings vs the cars they were original too.
If you want the accurate look just find the 409 casting with bleeders.
Maybe MR 70 or Rick H can explain the misc casting numbers ????
Dont know what other cosmetic items you want to correct/change on your car, but ask away....here or at the nastyz28 Original Forum.
