hi I'm new to the forums and I'm under going a swap on my iroc-z , I'm putting a lt1 and a t-5 my question is can i fit long tube and if so what kind ?? your help is appreciated

 

LT1 and a T5 makes for a marginal combination. The headers for a regular small block should fit the LT1.

 

I agree... You might be better off getting a T-56 and putting that in instead. The T-5 probably won't handle that lt1 for very long. And from my understanding, you can't fit long tube headers on f-bodies. Unless you get the ones that come in two pieces and you put them together... they didn't look very promising to me... Can't remember the name on them though
