please read
does anyone know of a place that makes headers or performance cams for a 2.8V6 for an 89 firebird? i know they are crappy engines and all but mine is running fine and only has 110k miles on it i want it to have more power than the 3.4V6's at least, all i need is about 20hp to match 3.4 but a 3.8 would be better to match.
2.8 is 135hp and 160torque, mine is about 155hp and 175torque 3.4 is 160hp and 200torque 3.8 is 200hp and 225torque Last edited by 89birdowner; 11-20-2003 at 08:45 PM.
