This is Simon's 66 Mustang. It's pushed by a 289 with 9:1 comp, 214/224 duration @.050 .472/.496 lift cam, GT40P heads, Edlebrock intake, Holly 650, Ford Motorsport Tri-Y headers and 2 1/2 to 2 1/4 exhaust with a H pipe and Flowmaster 2 Chamber tin cans. Also if any one reading this is thinking of putting the GT40P heads on there motor and needs any help let me know, we found some problems, and solutions while doing the swap so email me and I'll help you out.
