A lot of variables come in to play when choosing a cam. Our SVE top end kits for Fox Body Mustang 5.0's include a TFS stage 1 cam. We've found that this cam works well on a typical street car with supporting mods. The valve springs that come with these heads are good for .550" lift. We chose the TFS stage 1 based on a typical combination of EFI long runner intake, stock cubic inch and compression ratio, manual or automatic transmission, headers and 3.27 or higher numeric gearing. Other factors to consider when choosing a cam are your car's weight, gearing, induction, transmission, cubic inch, and, ultimately, the way in which you use your car. The TFS stage 1 cam makes good power and is very streetable.
