Engine towers are different though you can use the ones from the six. The tranny cross member isn't in your current powertrain so you will need to source one of those and remove the riveted frame mounted one you have at the bell housing. The steering column will need to be changed unless you use a floor shifter. The rear gearing for most sixes was a 3:73 while the autos used a 3:08, it will work but rpms will be up from other autos. I'm not sure about driveshaft length or slip yoke. New exhaust system. I would stay with the six but if you are sure you want to go V8 start gathering parts and reading swap threads on here. When you have every piece you need and a chunk of extra cash, do the swap.
so far
Engine towers for a SBC
Steering column for an auto or floor shift for same
Cross member for an auto
Grinder, chisel, torch, or other implement to remove bell housing cross member.
Standard set of hand tools
engine hoist
exhaust system
There may be something else I've missed but someone will probably chime in with it.


Before you do any of this, you should make sure the brakes, steering, and the safety/mechanicals are in good shape and up to handling the extra load. I would rather have front disc, power brakes and maybe PS before I started upping the engine capabilities. It don't matter how fast you can go if you can't stop.
