Guest KraZ4spd Posted February 21, 2003 Share Posted February 21, 2003 Will a stock (Vortec cover and all) 5.3 Vortec truck engine fit in a Z? I like the look of the silverado engines. I am concerned that the engine may to tall. Any ideas? Quote Link to comment Share on other sites More sharing options...
jeromio Posted February 21, 2003 Share Posted February 21, 2003 5.3 = GenIII = LS1 Iron, smaller, heavier < Aluminum, more HP IOW, why bother with the 5.3? Same hassle as LS1, but less bang per dollar. Quote Link to comment Share on other sites More sharing options...
