Need help identifying pinto cam please......

[X-pack-Glyn]

ive pulled a fairly new looking cam out of a pinto auto engine and it hasnt got the ford mark in the usual place.

 

it has stamped into the back 279 and the letter H then under it the letter P.

 

on the cam itself where the ford would normally be is "PS1" cast into it and what looks like O4D stamped above the PS1.

 

im wondering if its a high torque as the engine pulled well considering it had an auto box behind it.

 

the spray bar also looked new and fatter than a ford item and is a brassy colour instead of steel (part of a kit maybe).

 

any help apreciated ta.
