GMC Experts Needed..... 305 V6 Question

Hey guys,

I recently aquired a 1968 GMC 1 ton from a friend. It has a 305 V6 that runs sweet, but I have two questions.

1-How hard is it going to be to find power steering for it? I have looked around (6066 GMC board) with no luck. I have the gear box, I just need pump and brackets.

2-If the V6 ever gives trouble can I replace it with a SBC and keep the same tranny location? This is important, because the truck has a PTO dump on it, and I do not want to have to modify everything. I can change motor towers easy enough, but will it keep the same tranny location? Anybody ever swapped out a 305 V6?

Thanks in advance.

Finding a P/S setup is not too hard. I have had 4 or 5 of them, kept one and sold the others for $100 to $150. That included the pulleys, pump and bracket. I have a 4x4 and was able to use GM stock hoses to the steering box. They show up on Ebay every few months. Keep looking it is worth the trouble.

The normal thing to do when the 305 V6 finally dies is to replace it with a small block. Several local farmers still have fleets of those old trucks that get used a few weeks a year and most of them now have V8's swapped into them.

Like Erl said, they're pretty easy to find if you watch E-Bay. Stick with the 305, they're a better truck engine than a small block.
