PI Heads?

[mrmhrm9598]

I picked up a 4.6 out of an expedition today. the guy that I got it from said it was a windsor block with PI heads and that the heads were new. It has 13 valve cover bolts on one side and 14 on the other. And the oil fill is on the Passenger side. Does this sound like PI heads?

yes, if its a 4.6 windsor block then it has pi heads on it. btw what year was the expedition?

 

[mrmhrm9598]

He said it was a 99.

I got the motor to have an extra block to build. Is there any advanteges to a windsor block?

Get to readin...

Differences in blocks

 

[mrmhrm9598]

I read the article but still do not know which is the best block to build.

I like the remeo myself, there more readily availeble but they both will hold the same max power from what I've heard

It really doesn't matter which one you build. You can put romeo heads on a windsor block and vise versa. Hell you can put 4v heads on a 2v block if you want to. Its just the main caps are different and the location of the freeze plugs. I would suggest finding an aluminum block if you want to build a motor. They are just as strong and are lighting then the iron

What would 4v heads do on a 2v block?

 

[ninjastang125]

Be low compression. Would run like crap without boost

I hear alot of people asking how they can tell if the have a set of PI heads or not. when I removed m valve covers they actually have PI stamped on them Do all PI heads have this?

 

[fast97gt]

Well yea, if its a windsor motor. The remeo you have to go by part number of visual inspection, and the intake ports a square not tear drop shaped.

 

[mrmhrm9598]

Mine is the windsor. I still need to find an intake for the PI heads.
