This sounds intriguing. I will do my research, and go through the stash to see what I have that will get the juices flowing.
Ok, read through the official rules and picked my car. I am going with a 65-66 mustang. I owned a 65 Falcon Futura sedan with a two bbl 289/C4. At 55mph it got 25mpg and had plenty of torque, and since the 64-66 mustangs are re-skinned Falcons, they should have comparable specs. (Little known useless fact, 1965 Falcon sprint hardtop was lighter and faster than its brother, the 65 Mustang hardtop with gt package.) If i understood correctly, the rules said you could upgrade the cooling system with electric fans and chassis reinforcement. So for the sake of period correctness. I could add subframe connectors, over the counter heavy duty shocks, and front and rear sway bars. This era Mustang also was available with a posi rear-end.
Does all that seem correct to those who have done this before?
