So, I am looking through the Canadian GM parts manual and I come across a phrase that I'm scratching my head over. Next to the power steering pulley part number it reads: "1969/ALL WITH 396-427 ENGINES T/W FIELD INSTALLED CAR COOLING." What is considered 'car cooling'? In other pulley applications,...

On the 65 over the last while, when I've been out driving on the highway at any length of time, at, say 2300 RPM sustained, a rattle at the back starts. Starts quiet, not constant then becomes louder and all the time. Sounds like it's near the right rear tire. Travels right through the body and it's alarmi...

So I have the 4 bolt block, 858 square port heads, 6223 crank, dimple rods and factory 069 intake. What I have to figure out is what pistons , cam and lifters to go with? Obviously cant go with the factory specs solid lifters and high dome pistons have to be able to drive this thing on todays gas

The 327 is needing it's first oil change. Still has the Lucas break in high zinc oil in it, along with half a bottle of Comp break in additive. I took no chances on the cam break in, and it appears to have worked just fine. I have a high volume oil pump, no bypass filter adapter, and will always run a no bypass...

Every so often an oddball little part is still available from GM for our old cars. This is one of them. I ordered it last week because I didn't like a piece of straight bulk PCV hose, it takes too big an area to get from the carb to the PCV valve in the left valve cover. This hose, as you can see, has a nice molded...

In my 65, I have my old 67 327/275. the Qjet was pro rebuilt about 10 years ago. In shuttling the car around (not on the road yet), today, for the first time it started running poor. Started just fine, but ran like it was short a cylinder of two, which surprised me, as it always started right up, ran and idled...
