340 warranty block

Looking for a 340 warranty block with documentation. There should be rivets and a tag that say warranty. Needed for 1961 Dart. Since the warranty was 5 years/ 50,000 miles, any 1968-1973 blocks will do.
looking fir original engine also: H1R263395 - probably in Alberta, Canada


A 69 Dart? Not 61?

My 69 fish has a 383 Warranty block and is only stamped on the oil pan rail near the starter. PT383H25130103,

Translated is Power Train Trenton, 383, High, 5/13/69 and 103 engine that day. I believe! The website that decoded is now defunct and I did not record it all!
