The 285/265/255hp engine has the gt-40 head, flat top pistons, 4 valve reliefs, 480 lift cam.
As I said earlier the 270/250 use the gp40p head (explorer head). The 215/240 engine is basically the explorer engine, Olin Welborn had this engine in his 68 Mustang in k,l,m crate motor when was running it in IHRA a few years ago.It also has the gt40p heads. The 95 Mustang that I ran in M/cm was the 270/250 engine. I tried the 285/265 when I first built the car but found that the gt40p head were a better head and at that time was worth the 15 hp difference over the gt40 head. I believe IHRA lower the hp to 255 last year. Gary Peterson
