hi,
i wanted to know, if a lt1 intake manifold is ported for 58mm tb,
will it work if u want to use the stock tb?????????

 

Yes, it will. The stock manifold can accomodate a 52 mm TB without porting, so it's the same scenario really.

 

hey madwolf, can the xe 224/230 pass our chicago emissions????? or am i better off getting the lt4 hotcam kit? not a track car, just want to whip some ls1 and cobra *** on the street. i want a kick *** street machine.my mods are in my sig. thanks
