Is there an online tool anywhere that you can input your engine serial # and get some background on year of production or other details? I've done a google search and had no luck at all with this...

My engine was originally believed to be a 327 when I bought my truck, but is now believed to be a 350... whatever the case I'd like to know for sure...

Serial Number (found on top driver's side) is 3892657

Any ideas??? Thanks in advance for your help... headscratch
