Thanks for the help guys. The cam is the x303 andc the motor is form central coast mustang AD in 5.0 Mustang mag. I have figured for new p heads with lifters, cam, gaskets,headers, shipping, and rockers I will spend about 1500 hundred. For the same with setup with used gt-40 heads about 1200 hundred. Then add in the short block for about 8 to 9 hundred?(have not checked locally yet) I'm looking at spending about $2000 to $2500. Plus the long block is assembled and ready to go. Just slide it in and go.
I need to let the guy with the heads know today if I want them. What would you guys do ? Thanks again for the help.
