4.6 Paint markings

[Fordmotorsport1]

I bought an 03 Cobra with some pretty extensive mods and only got hearsay as to what was done to engine. I took the blower off to replace the hard line coolant tube from the water pump and saw some paint markings.. Was hoping someone could help me figure these out if they mean anything. back of the valley has 120700 on the sides of the valley are to80/to40 on driver side and to80/to80 on the pass side of the valley. Thanks for the help.

Never seen those markings before, only thing I know about regarding ford painting anything is the replaced head, would have blue spray painted lines on them so you could tell they were done.

Very odd yes, has to be rebuilt I think, not sure a junkyard would put such markings on but never know I suppose.

I don't think that's a "T". It looks like a plus sign to me. Maybe something from the machinist.

Now you have me wondering what that could mean..+/-.080 what? haha..sounds like I need a new block so I know its done right.

It might be marking for how much is needed in those spots. I've seen machinists write bore sizes on pistons. If it's running fine and not using oil or coolant I wouldn't worry about anything.

This and could the 120700 be the rough mileage as to when the measurements were taken?

Car only has 116k on it though. Could be a rebuilt engine I guess but I'm still wondering what is +080
