I have seen few of them run at local track before . Not sure what was done to them here is a manual one vs 392 Charger Scatpack here is a one with the A10
After owning 3 Mustang SVO's, an 85.5, 86 and 86 Comp prep I can verify that yes it was on par with the 5.0 GT's. I never had problems hanging right there with the GT's and also the 86 Vette's. In the twisties though the SVO's were better. With the Koni adjustables all around and the balance of the 4 banger it was a great handling ride. Really fun car to drive.
