Thanks for all the info, this is a car that I use as a daily driver during good weather, and I am not really interested in racing it, just want it to keep looking good and run better than stock. It is a 90 GT and I bought it in 89. Most of the miles it gets is about 20 miles of freeway driving each way to work and a little around town, I just ordered new headliner, carpet, visors and already have a new set of seat covers ( OE style) that I plan on putting in over the 4th of July weekend. The seats are grey tweed but I went with Black for the other stuff. Which intake would be better for low end power, the ported Explorer or some other ? It does have an AOD trans with 3.73 gears and it seems to have lost some low end with the TFS heads and cam as compared to the stock cam and gt40 heads, but it has more high rpm power now, and the cam sounds better.
