What is the best year ,make and model to get a 3.4 bottom end from? One that would need the least amount of fabed parts,brackets, etc...and use the most stock top end parts.
the one that you want is the 93-95 camaro/firebird 3.4. It can be referred to as the L32, but be careful because almost every time someone refers to an L32 they are talking about the 3800 engine which is also referred to as the L32.
