Guys im new to site. I do own two mustangs. One is a 07 shelby gt500 and the other is 65drag car with all cast iron 351c. We are having a debate on another forum on quickness of a 83. I build engines for a hobby and i say i could get the 83 to run mid to low 12’s with cam header and intake swap. Has anyone done these mods? Or know someone? We did a 306 for my sons mustang 2 basically with those mods and 355 gear and it runs 8.0 in 1/8. Thoughts anyone?
