got some good reply's, cheers

Steve, your spot on with why i dont want the engine/blower sticking out the bonnet.

Like i said i'd like to keep the cost down to begin with and just concentrate on getting the basics done i:e engine in car and running 100% then modify it as you would any other car. It wont be anything special as its a 5 door sierra xr4x4 shell all be it a mint and rot free one, just want something different that goes well and sounds awesome but is a bit of a sleeper.
