Any help is greatly appreciated, simply not looking for "why don't you use the search tool" a couple of answers can send me back on my way to picking up my old knowledge.

1)How many miles on chassis is good, and where's the best place I can find one?
2)And Motors as well as a turbo kit ?
3)Why a lower size head on a bigger block?
4)Is an ls the tranny the way to go?
5)Would you recommend buying an already fast car off this website for starting?
