Victor this is what I found doing a google search and this was on the Hemmings site. It will show you what engine it was by the prefix, but as far as cubic inch or displacement I didn't see anything as far as I dug. Good Luck, John
1934 U.S. CHEVROLET MOTOR SERIAL NUMBERS BY MONTHS
11 September 2001
Prefixes: "M" FOR "STANDARD"; "MR" for Right-hand drive "Standard" although Canadian Walkerville-assembled r.h.d. Standard motors were evidently prefixed “RM” which should be the case for Flint-assembled units; "K" for "Master Series C[K]OMMERCIAL"*; "T" for "Truck; "R" for Right-hand drive Master Series"; "RT" for "Right hand drive Truck". Trucks used Master series motors although export vehicles may have used either series and there may have been "RK" for "Right-hand drive C[K]ommercial"*
"MASTER" = "MASTER SERIES DA" and "STANDARD" = "STANDARD SERIES DC"
