Well, although I have a pre 4cyl now 302 EFi 88 mustang, I had an 89 camaro with a 350 tuned port and I had no problems and it whomped on several 5.0's. oh, it was a stroked 350.. 383 so it had some money into it. Since I have had my 5.0 I have had no problems trying to get parts and it seems mustang owners are a little easier to talk to, not all about my car is better than yours, type of deal.. atleast in my experience but i guess that is just the type of person. Go with what you like.....
