The holes are the same size. All the water holes on the head intake surface, two front two rear are the same. Now how long have you been working on Pontiacs?

Robert Williams<HR></BLOCKQUOTE> Been working on Pontiacs for a while. But haven't on a 301. I thought they were the same. Did some looking and read and was told they were not the same. So, I called Year One. The dimensions they gave me were different. After your post I checked again. They show a 1.19 for the 301 and 1.89 for the non 301. When I heard that a second time it didn't click. There is no way the non 301 is that big. Did a little more digging and looks like they are the same. Which works for me. I'll hunt around for a less a cpl for my #62 heads. Will make the routing of the cooling lines much easier. Thanks for making me look some more.

One of my friends is running RA-4 heads on his T-A. He has the 301" 90 degree heater nipple on the back of both heads and the water lines run from the nipples on the back of the heads to the water crossover on the front of the engine.

Well, I got the car back on the road today. Impressions:
1. The flow through the radiator is GREATLY increased. Probably close to 2x as much flow. 2. The car ran about 20 degrees cooler than usual. There's a hill near my house, and the car would always go up over 200 degrees when running up it. Today, it got to 185. 3. Unfortunately, after heat soaking the car, and doing a couple of three gear WOT passes, it still ran around 205 degrees. This is still about a 15 degree improvement over what it did previously. Next step is to get a smaller water pump pulley. I'm beginning to believe, however, that I just need a bigger radiator. I'm going to drive the car to work tomorrow (30+ miles each way), so we'll see how it does. |

It got replaced by a MSD billet distributor (they were about the same price new). It figures, because it died about a month after I bought the Mallory advance adjustment kit. |

I wanted to keep mine under the manifold. It is a Victor, so there is reasonable room underneath it. Below are a couple of pictures of it.

How big (Dash number) are your lines and fittings,
Jim? Tom V.

It has been so long since I did it that I don't remember the size for sure. I think it is #12. The line goes into the backside of the manifold water cross over. We welded a pyramid onto it to assure there was enough meat for a threaded fitting. I already had a nipple welded onto the front of what used to be the PCV hole in the valley cover so I could install a rubber hose to a breather. That blocked the path to the passenger side of the manifold cross over.

If they are not #12, then they are #10. It seems to me that I was going to run a #10 from each side and then "T" into a #12, but I might have ended up with all #12. I will have to check to be certain of what I ended up doing. I do remember that the fittings and the hose were pretty expensive. I originally did It out of rubber hose and plastic fittings to the front cover, but I didn’t like how it looked or how the water would circulate.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
