New Buildup! 448ci STG 2 SE Hyd roller.. an MPG motor

Jim

Did you install the cam straight up or with advance?

Thanks

Paul

 

Thanks Jim for another data point to file away in my mind. Again, you're awesome for both making great builds and then sharing the details with the results.

 

On it's way!! (Re: 448ci STG 2 SE Hyd roller.. an MPG motor)

Dear V-8 Buick fans of "assertive" family wagon engines,

Shipping the engine was delayed by . . . . global warming!! :grin: Uh, not quite, but actually by my desire to add a Vintage Air system to the project.

Jim had to pull teeth to manage to get his paws on the darn compressor and then fashion a bracket for Sanden compressor. Here is a teaser photo of how the engine worked out:



Jim shipped the engine out on Monday. It is supposed to arrive in Orinda Motors sometime on Thursday. Just in the nick of time to be displayed at the Orinda Classic Car show before being installed.

I'll post more pictures when the engine arrives.

Stay tuned!!

Cheers, Edouard :beer

 

When you get a chance post a picture of the back side of the AC/Alt bracket. I had to slice off a section because of interference with the Stage 2 headers. I'm curious how yours was modified. Thanks.

 

Paul,
Cam was actually installed 1* retarded. Shooting for zero, but that's not always available.. it's what was required to get the correct DCR numbers we were after.

Sorry, I missed this when you asked.

Here is that Pic Bill.



It's a viable option to use a compressor like this, for AC with STG 2 heads.. The big A6 compressor would be tough.

JW

 

Thanks Jim. I'll definitely go with the smaller compressor.

 

Damn, I never thought I would be looking for a steel long waterpump A/C bracket. I even saved an aluminum short waterpump one "just in case" and look where I am today.... I just about bought one of those new A6 A/C compressors; I understand now that it won't fit with the Stage 2's.

 

I got plenty of them Adam..no worries..

And yes, I never had the situation arise of AC on a STG 2 motor before... and was surprised when I was doing the initial mockups.. I knew that the hole was missing for the rear bracket mount on the STG 2 heads, but was unaware that it would be damn near impossible to use that Delco A6 AC compressor. It's a third again longer than this Sanden one, and would end up right over the number 2 header pipe.

JW

PS.. Steel bracket can be used with the long or short pump.. the difference really is only the offset of the water pump pulley.

 

That roller cam is where it is at. It really lets those good heads work.

 

Since I suck at fabrication and the hoses would have to change anyways, what about using an A4 compressor? I've used the 231 accessory brackets. The A4's were used for around 20 years or so on everything from Suburbans to small cars so must work decently enough.

 

Yes, the Radial compressor would work for packaging for sure. I am no AC compressor expert, but seem to recall that there might be an issue with the constant run POA system and that compressor combo.. The radial compressors were all cycling systems.

Might be nothing, and your exprience may prove otherwise, but it might be a good idea to check with an AC specialist.

JW

 

Good point, I can agree with this. I don't have the answer to that either and didn't think about that difference in setup. Are the sandens constant or cycling? (last A/C question I swear!)

 

I beleive they can be used either way.

And thinking about it, I know the A6 compressor does not like to cycle, ran into that this year.. but I would be willing to bet that Radial compressor would not care about a constant run. The A6 does not like to cycle, because of it'small diam clutch.

JW

 

Many of the updating kits retrofit to a clutch cycling system if I understand correctly.

That is another thought I hadn't considred, although on a 64-67 it looks like hood clearance on the alternator might be an issue, unless the picture angle makes it look worse than it is. Certainly the radial units should still be readily available and reasonably efficient compared to the A6.

Thanks for the info Jim. I have never used a long pump, so learned something new today!

 

It's high up, but it is about level with the top of the air filter housing. But looking at the Sanden installation, plus the hoses on that one look like they have to connect to the top, which looks pretty high up too.

 

Da' engine has landed!! (Re: New Buildup! 448ci STG 2 SE Hyd roller..)

Dear V-8 Buick fans of assertive engines . . . . .

Well it was a long time in coming and it squeezed in just under the car show deadline but . . . . . . .

da' engine has landed in Orinda Motors!!

They called me as soon as the engine arrived and I only live about 15 minutes away. I rushed over with Jim's very thorough unpacking instructions but . . . . it was too late!! Da' fellers over there had already pulled the top off the box and were gathered all around . . . . drooling!!

Here are a few arrival photos:







No doubt, another JW masterpiece!!! :TU:

Stay tuned for additional news bulletins on this evolving super-cool engine story!!

Cheers, Edouard :beer

P.S. I sure would feel better about the National Endowment for the Arts if they were funding sculptures like this!! :3gears:

 

It's an awesome sight! I love seeing the port for the O2 sensor in those headers! You are going to have a very fly ride, you lucky devil!

:beer:beer

:bglasses:

 

very nice!!

 

Raw video of the engine (Re: New Buildup! 448ci STG 2 SE Hyd roller..)

Howdy V-8 Buick assertive engine fans,

Another update, I took a rough video walk around of the engine using my iPhone 4. Admittedly a bit crude, but perhaps that will show some details that aren't visible from the stills.

<iframe src="http://www.youtube.com/embed/PygWnPWgCIU" allowfullscreen="" frameborder="0" height="315" width="560"></iframe>

This was taken before the EZ-EFI unit and exhaust headers were put on for show and the engine was still sitting in on the shipping palette.

Enjoy!! :3gears:

Cheers, Edouard :beer

I have a question.

How did you get that square bore single plane flange on the EZ-EFI throttle body to adapt to the spreadbore dual plane of the B4B Edelbrock intake?
