As a fellow big block Mustang owner, I like it! And this reminds me, I should create a thread on my car.
FE valvetrain is complex, be sure to install the oil restrictors in the heads and spring for decent valvetrain. Also, do multiple test fits of the intake to the block heads. Since they all meet - the intake has to match on 3 sides. I just installed a Performer RPM and despite spending almost $700 on the intake, had to grind every bolt hole slightly to align to the heads (also Edelbrock). This problem only gets worse when the block has been decked.
