Brackets and Pulleys

I have a 350 with 461 heads w/ no acc. mounts from a 69 camaro that I recently swapped into my 91 firebird. I am having trouble figuring out which brackets to use because I 've read that no acc. holes means short water pump stlye brackets, but this engine has a long pump and had alternator and ps on it before. Would it be easier to switch to short pump and use those style brackets?

All 69 and up heads had accessory holes.

Yes, you are correct -461 heads do not have acessory holes. You could maybe go with http://alangrovecomponents.com for brackets.

You may have to change over to long water pump and attach accessories as best since the accessory holes are not in the heads.

If you use the short pump brackets, you'll have to swap the location of the A/C compressor and alternator. Wiring will have to be changed to reflect the relocation.

Personally, I'd go for the 91 mounting system. Be sure to secure the alternator at three points, ie, front case, rear case, and belt adjustment hole.

Alan Grove has mounts for the short and long water pump that don't bolt to the heads, so you don't have to switch sides as stated. I have 461 heads on my '69 and my engine builder drilled and tapped one bolt hole in the head. I'm not sure what is needed on a '91, but things can be done. I would go with the long pump if possible.
