I'm really new to Pontiacs and just bought a 67 Tempest with a 326. I want to upgrade to a bigger motor, but am on a budget. I found this 68' 400 through Frank's Pontiac Parts and would like your opinion on whether this would be a decent engine for me to purchase so I can upgrade it to a more hi performing motor.
Here are the specs from Frank's site:
1968 Pontiac YC 400 2brl Engine with #15 Heads $650. Runs good. Complete engine minus A/C, exhaust manifolds & air cleaner.

I called their shop and spoke to them. They said the engine is still in a car, but is in running condition. The engine smokes a little bit right now, but again my plan is to tear the engine down and rebuild it. Do you think this is worth it for me as an engine?
Thanks in advance for your help!
Johnny
