I am trying to find the cumbusion chamber volume for Ford E7TE heads. Some sites say 60cc to 63cc. Please give me your input

 

The E7 castings range from 60.3 to 63.6. Some say 64 and I have heard 69? But should be around 9.5 to 1 compression with stock pistons. I have a set of GT-40 P heads and they are 59cc chambers.

 

the gt40p's i'm looking at say 60cc, what are these on, how may springs on the valves?

 

The heads i have are still in the box. You can find them on 97 or 98 up 5.0 explorer/mountaineers.

 

got the gt40p heads installed, sounded like the tappets rattling, found the holes for the push rods are too small, rods touch against the side of the holes, drilled 2/3 the way afrom bottom 1/2" in dia but the top 1/3 is between 3/8" and 7/16". anybody else have this problem, took off heads to confirm this and noticed #4 cylinder gouged, wrist pin let loose, having it resleeved and bored out to fit piston, hope machine shop will cover part of this, but they say not our fault, considering they pressed the pins in, i think they should pony up some for this, don't you?

 

Jolbca do you already have a set of these heads or access to them so you can check them yourself to find out the cc?

 

Yes I do and I will check the volume Thanks
