The Stovebolt Site Forums The Shop Area General Truck Talk 1965 GMC V6

I own a 1966 GMC truck and was looking at a 1965 GMC truck for parts. The 65 has a V6 in it that looks to be original but I have never seen a V6 that old and don't know anything about it. Was looking for some info. Thanks

This group has all sorts of info on the V6

What you have will be a 305 cid, they were also made in 351 and 478 as well. These are big, heavy engines, I seem to recall that they weigh in around the 900 pound mark. They are a very torquey engine, not fast, but very powerfull on the low end. There was also a v-8 and v-12 based on the same block, and deisel versions that used different heads and pistons. I've poked around on the site that chevhelper posted, it's very informative.

Hi 66impala,
have a look at my truck in the gallery.It was a '66 GMC, now a Chevy. It has the 305v6 in it yet, all rebuilt. I got all my info for the rebuild from 6066 GMC Truck (web site),as chevhelper said, alot of good info.
Ted.

A 60 degree V-6, Not 90 degree like most bent engines. Jeep just came out with a similar engine for their Wrangler line.

I thought it was a ninety degree odd fire engine, like the early Buick V6 except alot bigger and heavier. Obviously, I was wrong. Other than the 3800 Buick and 4.3 Chevy engines, all recent V6s have been 60 degrees.

Thanks to all. The web site is great. Mark
