Also, it doesn't appear you'd be getting any accessory brackets or pulleys with this, so you'd have to buy all of this...where if you swapped to another small block, you already have it...same goes with wiring, it would have to change.
the wiring is just extending a few wires nothing big. i agree with the brackets and pulleys. they can get pricey if you need to buy them..
Did you ever wonder why they never sold many 383 a-bodies and why they were discontinued? The 340 was just as fast, handled better, and came factory with power steering. You'd have everything you needed but a driver's side mounting bracket already to swap in a 340 or 360.
