1 5/8" Primary's on an LS1? Hey Everyone.
Ive got 1 5/8" LT Headers in my iroc that i converted to work with my 5.3L.
Ive found a great deal on an LS1 block and im planning on swapping it into my car. How bad would the 1 5/8" Headers be for the LS1?
Would they be better then manifolds until i can afford the only other header option for my car? ($800 stainless works headers)
Thanks!
Sheldon

If I'm not mistaken, I think TPIS offered (or still offers) similarly sized primaries for Vettes. While it certainly isn't ideal (I think 1-3/4 is the best all-around size), I still think you'd be better off with those than cast iron manifolds.
