since your signature didnt show up, im gonna assume you have a 1990 LX/GT.
i went with the trick flow stage one cam. they are the cheapest roller cam out there (by far) and come pretty well recommended. you can re use your roller lifters. it has a mean sounding idle but runs relatively smootly and pulls pretty hard, particularly 3000 and above. id recommend gears to go with it. i had 3.27s in my car with this cam and although it was still pretty quick, you would often be well beyond the speed limit and still find the car pulling hard and wanting more. the rear is out getting 3.90s today. cant wait to see what that does to it.
