Searching for a 67 400 YS block, with a standard bore and casting date prior to October 1966. I know that’s probably wishful thinking to find one that fits all that criteria. Please let me know if you have something. I’m in the Dallas, Texas area.

Frank's Pontiac Parts has one for $850

Thanks Frosty! I spoke to Frank about this block soon after he acquired it. Frank says it will have to be bored .060. I was hoping to find one that can be bored 20-30, at the most. I keep an eye on Frank’s site for new arrivals. I appreciate you telling me about this one.

You're welcome. I have a list of other junkyards. Frank's is the only dedicated Pontiac yard I know of. Plus they publish what they have online. All the rest you have to call and see if they have it - hit or miss.  Keeping checking eBay, Craigslist, and Facebook Marketplace too. Hemmings.com might also have something.

 

Since you are in Texas, you could try these classic wrecking yards:

 

CTC Auto Ranch - Denton Tx

Brown Auto Salvage - Sunset TX

K&K Motors - Graham TX

 

You might get a lead from Texas Trans Am in Mansfield TX but they do specialize on Trans Am parts and not GTOs. However, they might know someone with a older 400 block.

Thanks again Frosty!  I’ll check with the other places you suggested.

You're welcome. Let us know what you find out.
