cost for Butler 455 build?
I'm considering taking my '73 455 to Butler for a rebuild. It is stock bottom end with a roller cam and rockers, Edelbrock rpm, intake, Avenger 770 carb and larger valves in the 4X heads. I would like to rebuild it with a forged rods and pistons, keep the stock crank and likely use a set of aluminum heads. The is a street only build, so something in the 450-500hp range with the focus on good off idle torque and midrange is my goal. This is going into a '67 GTO, backed by a Turbo 400 and 12 bolt with 3.31 gears Any guys here have a feel for Butler's pricing structure and leadtimes? Suggestions?
