Howdy gents.  Was the standard engine in the '65 Riv the 401, or was it the 425 in '65?  Thanks.  Rich in Tampa.

I'm going to sound old....   Too small to read!  Control + just makes it blurry and large.

 

I think it says 401 is standard engine.

A 401 was the standard engine for a 65. If you are looking at a certain car there is a stamping code on the passenger side of the block in the front where pushrod cover seals to the block. The standard 401 would be stamped LT. Optional engines would be stamped LW for four barrel 425 and LX for dual four barrel 425. These two letter codes are the easiest way to identify 63-66 nailheads. The first letter IDs the year 63=J, 64=K, 65=L, 66=M. The second letter identified the displacement and carburattion, T= 401 single four barrel, W=425 single four barrel, X or Z for dual four barrel 425 (Z was used in 66 only).
