thanks tlederman, knowing some of the history on the truck, I do not believe the past 2 owners would have put an older engine in for any reason, my bet is they would have replaced with a new engine.. just my 2cents..

but I also looked at the oldcarmanual.com website. and found that there is not a listing for ANY 1947 truck information. Has enyone else found dead ends with the 47 trucks?

I will most likely request from GM Customer service the restoration kit for the 47's.

Using the car serial decoder, I'm guessing I have the 216.5 cid, built in Flint, with a Heavy duty Clutch, and it was the 135,200 th off the assembly line..but being "mr overkill" (and sometimes too anal), I want to verify it for the possible future rebuild / or replace with a 235...
