1967 Pontiac GTO - Converting standard steering to power steering

[GTO-1967]

Hi.

I just recently purchased a 67 GTO that had a Rotisserie Restoration and an engine and transmission change.  The 400ci has been replaced with a 455ci and the four speed with a five speed.  I'd like to convert the standard steering to power.  Has anyone on the forum done this and could you tell me the things to consider when making such a change?  Thanks

I did the opposite on my 65 GP - power to manual.

You will need new steering box, coupler & appropriate pitman arm. Idler arm is the same on mine-yours might be different. Last thing is extra pulleys on your harmonic balancer to accommodate the pump drive belt, and ensure you have enough room for pump to st. box plumbing. Oh, and a bracket to attach pump to block. Personally, I love the uncluttered engine bay look and the purity of manual steering. Ames should have most things you'll need.

You will also need a new dual belt pulley for your water pump. You will have two belts now. One for the alternator and one for the power steering pump. Again Ames or most of the online catalogs should have what you need. Don't for get the power steering hydraulic Ines between the pump and the new steering box. For what it's worth, I would get a quick ratio steering box to make the steering more responsive since you have to replace the steering box anyway. Anything 16:1 or lower. Stock units were 24:1 which was about 4-4 1/2 turns lock to lock. 16:1 is closer to 3 lock to lock. Inspect your rag joint too.

You know what, I didn't even notice the photo. I was too busy expounding my innate knowledge of Pontiac steering. Yep, that's a fine looking car.
