1964 F100 Vin Engine code

I just picked up a 1964 (I think) F100 for a friend. I have figured out most of the Vin / warranty tag info but want to be sure on the year and I haven't found what engine size, code A. It's a straight 6.
Here is the tag.

F10AR750399

WB 115, Color M, Model F100, Body 281, Trans C, Axle 09, Max GVW 5000, 129hp @4000, DSO 75

Thanks for any info!

SMADAW, WELCOME TO FTE !

At first I would have guessed an 'A' engine code in a 1964 F-Series Ford truck would indicate it to be a 223 straight 6 ( I6 ); but, the HP and RPM don't match up. A typical 223 was rated at 114HP @ 3600 RPM. Now a 240" I6 was rated 129HP @ 4000 RPM.....but I'm fairly certain 240s were not installed in 1964..they started in 1965.

Which side of the engine is the carburetor on ?

Everything keys off of the last 6 digits of the VIN which gives the model year. Without the correct year everything you try to decode could be off.

F10 = F100-4x2

A = 240 6 cylinder

R = San Jose assembly plant

750399 = September 1965 build month - 1966 model year

115 = wheelbase in inches

M = Wimbledon White

F100 = F100 4x2 5000 lbs. gross vehicle weight rating

281 - 2 = Medium blue crush vinyl and medium blue match stick pattern vinyl - 81 = 81A Standard Cab

C = Ford 3-speed light duty manual transmission

09 = Ford 9" 3.70:1 (3,300 lbs rating) non-limited slip

5000 = Gross Vehicle Weight Rating

75 = Phoenix, AZ district sales office

Thanks BarnieTrk!
Carb is on the right / pass side.
Looks like TA455OH answered all my questions. Thanks!

Why would I ask this question?

Because its a quick way to tell the two engines apart.

The 223 has its intake/exhaust manifolds on the L side (and the carb) and the 240 has its manifolds (& the carb) on the R side of the engine.
