ls1 mani's
 

is there any problem with using ls1 mani's for a front mount turbo? I know truck mani's are the top choice i can just get my hands on some ls1 mani;s easier.

Yea you really cant use both of the stock LS1 manifolds since the position of the pipes will suck. You can get away with keeping the stock passenger side manifold and using a flipped passenger side truck manifold facing forward on the fbodys drivers side.
