Blusmbl I don't plan to run an IAC, I will drill all the runners for a vacuum line in order to make a small chamber for a common map signal. I'll turn on timing control to help maintain an idle speed. I will only miss it on cold starts most likely.
Right on- you should be ok. I think Roush only did it because they sold the 402/427 8 stack crate motors as turn key solutions that usually went in Cobra kit cars, so they wanted the best drivability possible when it was cold just to be safe. Also, depending on your cam, you might have to blend between alpha n and speed density off idle.
Edit: Rich, yep, that was one of them. The white SN95 had an 8 stack 427 with a TKO 5 speed. We also had a red fox GT hatchback, it had an 8 stack 402. The red car eventually got a 350 Chevy crate motor, then an ex-Nascar motor, then a milder carbureted Windsor. An old coworker finally bought it and now uses it as a track car.
