Hello and a healthy, happy new Year!

As some of you know, I´ll get a new engine 467 stroker for my 1966 Lemans, which should be here in 5-6 weeks.

So I want everything going right this time and a point I was wondering already with the old engine is vacuum line routing. I browsed the forum but didn't find what I´m looking for...so I made a little diagram and would like to know if this will be the right routing for the vacuum lines.

Here are 2 pics of the engine

+1 Tuff, if it runs like it looks he'll have it made.

Hey Poncho, your vacuum drawing appears to be ok but when you get it piped in take a few pics and post them ok?

Thx for the quick reply, I will make some pics after connecting and post.

Another question. I don't use the heating, have had a hose from timing cover outlet to the back of the engine. But I would like to go without that hose on the new engine. Will it make any difference in cooling the water if i block the two holes on the engine?

Thx also for the compliments about the engine looks, I also hope it will perform the same way it looks like. I will post some more pics soon of the internal...but have to upload them to dropbox first.

Hi Poncho, your welcome and no the heater core hose is not essential for normal operation but if you run into higher undesirable operating temperatures or over heating issues you can always pipe it in for added coolant flow.

The car and engine are both nice looking  Cool  

Many carbs have a big pipe low on the front and thats what I use for the PCV. Only requires a small hose that way.

There is an other thing I would like to get your opinion...

When I bought the car the old 1975 400cui engine was in, after checking the numbers I found out the car was a 6 sprint, so it has only the 15" cooler and not the 17" one...

I already changed to a big tube 2 core aluminum cooler.

Because everything is out now I think about installing an additional oil cooler but I am not sure what would have the bigger cooling effect, to add an engine oil coiler or to add a transmission oil cooler. If the answer is transmission oil cooler, then in addition to the cooler on the lower radiator or instead of it?

Thank you

I use both transmission coolers, the one in the radiator and an add-on. Fluid goes into the radiator one first then the auxiliary on mine. If you want to cool the engine oil (probably not necessary, few Pontiacs need that), set up an oil cooler.

What I want is to cool the temperatures in general, because the radiator was chosen for a sprint six and now it has a 467 cui V8.

I just asked myself what will have more cooling effect to whole system (oil and water) and in my radiator the transmission cooler is crosswise on the bottom of the radiator, so the heat from the transmission oil cooling part goes up and heat the water cooling part additional. the 1969 radiator for instance has the transmission oil cooling part on the side of the radiator from bottom to the top of it, so the up going heat has no additional effect to the water. So my thought was, may be it is better to connect a separate transmission oil cooler, at least in the same size it has now and block the transmission oil cool on the stock radiator...

Or is this all nonsense, and I would gain much more temperature reduction installing an engine oil cooler...

I hope its clear what I mean?

Thank you

Hi Poncho,

I suggest you start a separate thread for your cooling system inquiries as most who look at this one will be expecting a question on vacuum. Also be specific if you were having engine/trany over heating issues or are just inquiring in general.

In this manner you will get a response from members specifically addressing engine and or trany cooling issues.
