390 revs to 4500 and thats all...
By Anthony - 11/11/2005 8:35:03 AM; IP 65.41.31.56
I have a 67 390 Mustang with stock intake and exhaust. Engine will rev to 4500 and thats it. I can accellerate to 4500 in 2nd gear and it will fall flat at 4500, but a shift into 3rd and it will pull real hard again until 4500. I have pulled the rocker assy's off and a couple of the valve tops look like they have been hammered pretty bad. Can this be valve float from old valve springs? If so,what would be recommended for a replacement spring?

Thanks
