The Stovebolt Site Forums The Shop Area Engine Shop 1962 GMC Truck

Hi everyone, I'm looking at a 1962 GMC pick up with a V-6 original motor 127000 miles. The owner and his wife have had it in their family since 1962. According to their testimony two weeks ago they were driving it on your Sunday cruise and their motor stopped . No loud noises nothing out of the unordinary just lose of power. When they tried to restart the only thing happen was they could here the starter try to turn the motor over but the bendix was just making noise. Dipsticks displays plenty of oil transmission displays plenty of fluid . What could this problem be?

Not sure if you are looking to buy or just helping someone.
Probably nothing expensive. If you are wondering whether to buy or not, push it to start. If it starts and runs good, offer less to cover repairs. You can also try jumping battery in case it is low battery.(my guess). To go into what could be wrong can take awhile especially if you don't have access to test and all that. You probably know what the list is already.
Push to start= roll it with clutch in and in 2nd or 3rd and pop clutch at about 5 mph. Is it an auto, 3 sp or 4sp?
Can't push auto.

List without hearing it: (and it does make some difference if it's just clicking solenoid or starter is turning some)
1. Starter
2. Solenoid
3. Ignition Switch
4. Connections, hot and ground
5. Battery (which can mean VR or Gen problems)
6. "they could hear" why can't you hear?

Thank you, I've purchased the truck and will pick it up Saturday. Saturday evening I'll post my finding and give you an update...

Those 305 V6's are boat anchors. I have two. After having it awhile, I am starting to like it. It weighs 800 lbs! No real performance. Lots of torque. 4 1/4 bore!! Aluminum pistons. The most advanced engineered motor of it's day. (oiling, cooling and strength innovations). Lasts forever. Many parts are hard to find. I have some motor related parts. They are known as a big block. I have a 1960 GMC 1/2T 4x4 K1000 series, big window, custom cab, short fleet.(wideside)305A and 305E.
Yours has the torsion front end. It will have a 305D (stamped on passenger side, top front of block). Check for build sheet in seat springs; having one owner documents: money. If it has side trim: money. "GMC only" parts are more rare of course.

So I'm looking ahead and I'm not finding simple parts like the front grill or the Grill letters, GMC, where do I find this stuff? If I need motor parts where do I find those parts?

The usual places, ebay, craigslist, Stovebolt wanted, swap meets and there is a website for 6066 GMC V6. 6066gmcclub. GMC specific parts, as I said, are a little more rare. PM if you need parts. Can't discuss specific "wanted" in this section.

Awesome thank you.... I'd like to post some pictures but I'm not sure how to do it....

Motor parts are available at most auto parts stores that have been around awhile. NAPA is a good place to start. I had a 305 V6 many years ago and I just could not kill it and believe me I tried.

Awesome thank you Martin

It might not be a bad idea to see if the timing chain came loose. I had this happen in the late 60s. It backfired once when I tried to start it instead of dying while running, though. Because nobody expected the timing chain we tried a lot of other things before looking there. If it had happened while the engine was running, I'd expect there would have been noise, however. Good luck!

Well as it stands the motor appears to be locked up....

I guess it's off to my favorite engine shop.... Unless there's an alternative solution!!!

I put a socket on the lower pulley and tried to see if I could get her to move but nothing...

I got a 62 with the 305 V6 from a friend that had it overhauled maybe 5000 miles ago and then sold his country place. I then traded it to my neighbor for rock plus spreading it on my driveway. He's done nothing with it (like all his projects) so if you think this could help you PM me and I'll put you in direct contact with him. He's usually very reasonable when selling abandoned projects. I see your in Virginia and he's in Texas so that's probably a killer.
