letitsnow Posted May 25, 2010 Share Posted May 25, 2010 Close, actually, the '90 runs 12's, the '89 runs low 18's and has the v6. My L28 powered Z, when running properly(not very often), is waaaaaaaaaaay quicker than the '89 Firebird, the turbo helps some.... The engine in my firebird is called the "LB8". http://en.wikipedia.org/wiki/GM_60-Degree_V6_engine#LB8 Quote Link to comment Share on other sites More sharing options...
