We pulled my buddy's enginee and pulled the heads off to move them to the refreshed shortblock. The id said E7TE but, the chamber the head was deeper than either one of us had seen before. Is it possible they were truck heads or are we just seeing things? There had to be 1/2 - 3/4" deep. The ones on my car were about 1/4 inch... He got a good deal on the car a few months ago but, spun a bearing. This poor car is so cannibalized. Lincoln block, weird heads, F-150 AOD, Unknown aluminum driveshaft, and a do it in your driveway 4:10 rear gear with major lash....like the u-joints are about to explode but, they are fine, It is a V-8 LX (title says so) but with 4cyl seats. Poor guy.....but he owns a MUSTANG!
