Converting 350 SB to a 454 BB

[plutopjf]

I have a 72 Chevelle and I am debating on converting from a 350 to a 454. I have many questions and concerns. I'll will start with this one.

Will I be able to swap the accessory drive with PS and A/C to a Big Block?

If anyone has any advice please feel free to lay it out ther for me.

Thank you...

You will need new brackets for both PS & A/C. They are specific to each, small & big blocks.

Also you will need a long water pump and not the short one for all the bracket to work.
