Living in South Florida ,The engine heat would have been a problem. I do notice that the Roush does not like approaching a stop sign at low speeds. I put the car in neutral and coast to the stop sign as I brake.
My car used to have the same problem. I replaced the carb with a 4150 hp with billet metering blocks, and had a guy that has worked on a lot of Roush motors dial it in, and the motor does not do that anymore.

Can't go wrong with a 427R / SR...
