What motor do I have

[Anonymous]

Sorry guys, read the other posts, and the edwin site, still can't figure it out.I have a 1965 Divco milktruck. Has an early OHV inline 6.(Everything but intake/exhaust on passenger side). Has 8 valve cover bolts, distributer @ passenger side front, does not have 3rd rib in drivers side. Plate in truck says 3.719 cylinder bore, which would indicate 262, but, as I said, only has 2 ribs cast in block, on drivers side.Casting #'s on block make it a 1963. (C3AE 6015 AC). Did all 3 engines have the same block (215,223, 262)? Is there any way, short of pulling the head and measuring the bore, of knowing which engine I have? And, are things like water pumps interchangeable between these 3 engines? Anybody know? Thx. JIM

I understand that 1965 was the year the 240 came out as an F150 and Galaxie base option. The big old trucks kept the tough as goats knees 262. This was similar to the big block 332 flathead V8 used in F350 trucks back in the mid 50's for oil exploration. Bascially, Fords truck stuff carried on for a few years after the passenger car stuff, with a bunch of changes in the last 2 years.

To check the stroke, drop the pistons to top dead center, place a plastic cable tie down the cylinder, and mease the distance from BDC to TDC with a straight edge.

Thats roughly the stroke, which should be around about 4.375" or so.

Tech inspectors use another method for measuring the total volume of one cylinder.


1)Park the truck on level ground.

2) Pull the spark plug

3) Drop cylinder one down to BDC, and fill it with water or lightweight oil to the base of the sparking plug hole.

4) Measure the amount in cc's, mils, or fluid ounces.


5) Then turn the engine to TDC. The amount displaced is the displacement of one cylinder.

6) Head cc or piston size don't come into it, but the true displacement for a 262 will be about 1/6th of the total cubic inch displacement.

This method was used in Australian touring car racing when there is a dispute over engine capacity and the tech inspector doesn't want to have the engine stripped.
