on a 67 with 915 heads, HP2 meant bigger exhaust valves, 1.76 instead of 1.60. I use to have 915 heads.

HP designates a High Performance engine which differs from the standard performance in the cam, valve springs, carb, distributor and exhaust manifiolds. '68 and later would also have a windage tray in the pan.

There is a lot of mythology surrounding the HP2 but the simple fact is that it is a HP engine built on the 2nd shift. A HP engine built on the 1st shift would just be stamped HP with no "1".

Price varies by geography and, of course, the condition and state of completness.

WORTH NO more than any 69 440

thanks guys and i looked on the pad again and found some other letters and numbers ill put them in order of how there stamped
E440
up side down A and an A on its side
4 28 HP2

[John Kunkel]

E is the year code for 1969.

4 28 is the build date April 28, 1969.

The A means it left the factory with .020" oversized cylinders.

Look for a machined flat area just above the pan gasket on the passenger side of the block, a full or partial VIN will be stamped there.

thanks john for the help

[challengerdude73]

this is the number i pulled of the pad by the oil pan 9B374821
please help

[John Kunkel]

B is the plant code for the Hamtramck (Detroit) assembly plant; in '69 Hamtramck built A-body Dodges and Plymouths and B-body Dodges.

[challengerdude73]

thanks but if A means .020'' then what does two A's mean then would it have left the factory .040''

[John Kunkel]

Probably just an error, a single A stamp is all that's needed.
