I was wondering if the super coupe cams are more aggressive than a n/a 3.8? I am planning a 4.2 build and was going to try to use as many factor parts as possible and see how.much hp I.can.achieve. I know a guy who built a svo2.3 with all factor parts like ranger roller cam etc... and achieved 400+ HP. I know building a n/a 4.2 will not yield that much but I am shooting for 275-300 . Just making my " grocery list " right now . I like doing things a little different that's why I got a Cougar instead of another mustang. Also I wonder if the 4.2 truck cams are different? Thanks for any input or suggestions.
