there are usually some of those adaptors kicking around on ebay or on jolly's 6066 gmc site. there have been a few on here for sale in the last while. i may know where there is one I believe in arizona for sale if you are really interested; usually in the 2-300.00 range
is the flywheel mounting 6 or 8 bolt

It would make a sweet boat motor....

cetacean6 · 05-02-2012, 03:12 PM

Are you saying you want the trans conversion system or the V12? There's a V12 for sale on craigslist in Wyoming ,but that might be too far for you.

1963c-10 · 05-02-2012, 03:24 PM

In that case, I have located one then. Now the real fun will be digging it out.
Its in a 63 GMC, looks like the 62 you posted.

1963c-10 · 05-02-2012, 03:32 PM

Was looking for the engine itself, but I have located one 10 min from the house. Thanks guys.

jonzcustomshop · 05-02-2012, 05:58 PM

they also came in these

padresag · 05-02-2012, 06:06 PM

they were also used as power sources for a lot thing like for irrigation pumps
there is a fellow in arizona that has the a/t adaptor for sale 250.00 plus shipping. a fellow I know just had one shippe from texas to b.c. here by USPS and it was 65.00

I believe that this one can be had for a couple hundred bucks. Thaanks for all the info though. I imagine the parts can be hard to find?

andrewmp6 · 05-03-2012, 08:35 AM

They also used Irrigation pumps http://www.6066gmcguy.org/Irrigation.htm and if i remember right some gmc fire trucks had them too.

jonzcustomshop · 05-03-2012, 10:03 AM

I am shocked at what those ads are asking for them.

1963c-10 · 05-03-2012, 10:36 AM

Yeah, I didnt know they were bringing that kinda money. Ive got a project in mind down the road and may pick the V12 up for it. I can get this one local for $400-$600. Which is quite a bit lower than the others.
