Hi,I posted this in the Impala net and they tell me i possibly have a COPO motor any help would be appreciated.
Hi,all I purchased an engine recently 1968 cast# 3935440 It has a really weird suffix T0419I5 yea a 5 and the vin# 18D166508 I see broach marks in the picture on the deck pad so i believe it was a factory stamp.
I believe the D in the vin is Doraville GA internet says Impala was building cars there from 65-70
my info could be incorrect so any help would be appreciated..
Thanks 964IMPALA
