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

What size primaries on the headers? Is that poweder coating?

 

Where did you get the bracket for the after market A/C compressor?
Nice looking engine you have there.

Bob H.

 

Headers are TA 2014CHC, which is the only header that really fits the 65 Chassis without modification. Head choice was influenced greatly by this, in fact, that is why it's a STG 2, not a STG 1. It's a 2" primary.

Coating is Tech Line Satin black, and I prep the headers and spray it here. Cost effective and it works very well.

As good or better than any other header coating, in my experience.

And honestly, you really don't have to run the little metal plate they give you, with a Holley, or that Throttle body..there is plenty meat to seal it up properly around the edges. I have never used it.

I think with some of the older Carter carbs, you had to have that plate.

I built him that bracket, by using a 72 up 455 steel Alt/AC lower bracket, and then modifying and adapting the supplied 455 Pontiac bracketry from vintage air.

Jim

Just reread the whole thread.. wow.. impressive build.!! Jaw dropping numbers for just driver motor!!!

Again wow...

I have an 82 Buick Regal , A/C heater delete, with a stone stock "71" 455 in it, the only upgrades done, a Edelbrock #2146 dualplane intake, stock Q-jet carb, HEI and long tube headers,
3" collectors with 1 7/8" primaries, true 2.5" dual exhaust.

2004R BRF code trans (manual lockup switch) from a GN, and GN 8.5 Rear with 3.42 posi, 275/60/15 (28" tall) tires out back.

Curb static weight with 3/4 tank of fuel, 3686 LBS.

With a trunk full of tools and overnite bags and 3 adults, on one its trips to the GS Nats it did a respectable 18 MPG.

Wishing and wondering what it would do with a similar build of yours in my "76" block I have torn down.

Lots of torque ,power and mpg.... that would go good with my Pro-Touring style build Im doing on my Regal.

Now gotta figger out how to put heating and A/C back in it since your A/C compressor bracketry just rocks.!!

 

Nice bracket Jim I think you could build and market them. I have seen inquiries in the past on how to mount aftermarket A/C compressors on our Buicks.

Edouard,
What are you going to use for a throttle/TV cable bracket?

 

throttle/TV cable bracket? Good question!! (Re: 448ci STG 2 SE Hyd roller..)

Howdy Chris, Larry, Ken, Bob, Jim, Bill, and V-8 Buick assertive engine fans,

Sorry to have been AWOL yesterday. I was preoccupied with the Orinda Classic Car Show which was why Jim had to hustle so hard to get the engine shipped out. I'll post on info on the show on the trusty "billy-goat" Wagon thread in a little bit.

To be honest, I haven't had a chance to look into this at all. I believe I got some of the needed parts when the transmission came roughly last year at this time. So I need to check to what was supplied by CK-Performance and work from that.

However, there is a considerable risk that . . . . . once I've looked into this - I'll be back here asking you guys for help!!

Stay tuned!!

Cheers, Edouard :beer

 

Re: throttle/TV cable bracket? Good question!! (Re: 448ci STG 2 SE Hyd roller..)

I too bought my transmission from CK and he should have included a bracket based on your carb selection. From what I've read the FAST unit uses a Holley style baseplate so any bracket for a Holley should work. What's nice about the FAST unit is the ability to connect electronically to a transmission control unit if you ever decide to upgrade to a 4L80E or 6L80E down the road.

 

If we can FIND it!! (Re: throttle/TV cable bracket?)

Howdy Bill and V-8 Buick assertive engine fans,

That's what I'm afraid of . . . .

Why? Because Orinda Motors got a batch of parts from CK . . . . Oh, about September 2011 . . .

I should have asked CK to send that stuff to me!! ou:

Oh well, on my queue of things to do is to send a picture of da' JW masterpiece to CK explaining why I haven't reported back on how nice the tranny is. That way if the part is indeed lost, perhaps I can sweet-talk another bracket out of CK Performance.

As I said . . . . stay tuned!!

Cheers, Edouard :beer

 

Posters that accompanied engine at show. (Re: 448ci STG 2 SE Hyd roller..)

Dear V-8 Buick assertive engine fans,

I created a set of posters to display next to JW's masterpiece engine at the Orinda Classic Car show. The posters explain some of the design decisions behind this engine and why it performs as it does. Keep in mind that I was attempting to educate the general public, so they aren't 100% technically accurate. I thought folks on this board would find them interesting, so here they are in Adobe Acrobat (.PDF) format. To draw in the "speed-readers" among you, I've also created a "super-sized" thumbnail image of each poster so that you have some idea of what you would be downloading.

The first poster attempts describe the modifications to the engine itself to get higher efficiency:



You can download the document here: http://www.canebas.org/Automotive/V8_Buick/Car show engine diagrams/Improve engine breathing.pdf

The second poster is based on Jim's dynamometer data and the actual 1967 Buick 430 dynamometer data that Devon posted here some time ago.



You can download this poster here: http://www.canebas.org/Automotive/V8_Buick/Car show engine diagrams/430 vs 448 Power diagram.pdf

The last poster actually consists of 4 separate pages. Only the first page is shown here as a teaser:



You can download this poster here: http://www.canebas.org/Automotive/V8_Buick/Car show engine diagrams/High tech improve online.pdf

This poster has photos that Jim took of the components that have benefited from technological advances in the 1960s and describes how these various components contribute to the improved efficiency of the engine.

Hope you'all enjoy them!!

Cheers, Edouard :beer

P.S. Thanks to everyone who has helped me out thus far in this drive-train makeover caper!

P.P.S. Stay tuned . . . . As tough as it was to get this engine, I fear the greatest - surprises - are still to come!! :shock:

 

Is it breaking the 1 of the 10 Comandments when you "covet thy neighbor's engine"?

JW
A few questions.. if I may.

Can the Eldebrock #2146 that I have give similar results as the B4B?

Can the Stg1SE be used instead of the Stg2SE, my is a 455 in a Buick Regal, got some dimples in my A-body 455 Buick headers for clearance or the Stg2's just better all the way around?

Custom grind on the cam? I didnt see it on T/A Performance's website

This build out of all the other builds I've read about , has totaly got my attention.... been wanting a similar build done to my 455 fo a long time.

 

As long as you get your own!! (Re: 448ci STG 2 SE Hyd roller.. an MPG motor)

Hi Chris and V-8 Buick assertive engine fans, . . . . . :3gears:

Of course not! . . . . so long as you don't try to steal this engine from my trusty wagon!! :grin:

Until Jim chimes in on these question, I can off you some teasers:

If you read through this thread Jim already answered this one. As far as Jim is concerned there is very little difference between the Stage-1 and Stage-2 heads in terms of performance. The reason to go with the Stage-2 heads was pragmatic. The only headers that will fit into a 65 Buick Special/Skylark with sufficient clearance attach to the Stage-2 heads. So this is a quirk associated with my trusty wagon.

You'll probably want more info from Jim on this one, but Jim does describe it as a "clone" of Buick's own Stage-1 cam. There is some specs on the cam at the beginning of the thread.

Hope that only further perks up your interest!! :3gears:

Cheers, Edouard :beer

 

Edouard , Larry

Thanks for your replies....

I do believe I have my mind set, that this is style of engine build I want for my ride.

MPG and HP!!

Edouard , I did reread the thread and did see that JW mentioned that there wasnt much difference on the heads, so thanks for pointing that out, I guessed I just glossed over it.
And don't I wont come after your engine. :grin:

Larry

Thanks for the info on the cam, I did notice the specs earlier in the thread, just thought it was an off the shelf item that T/A had . I do like it that it is a roller cam.

Wow I wonder if Santa is in Good with Tri-Shield 's J.W. and T/A Performance's Mike, I know what I need for Christmas!

One last question tho, could MSD's Atomic EFI be used in place of the EZ-EFI?

 

Atomic EFI might work, but . . . . (Re: 448ci STG 2 SE Hyd roller..)

Hi Chris and V-8 Buick assertive engine fans,

Once more you'll need the input of the great JW, but there are two obvious ways to think about it:

On the one hand, obviously Atomic EFI could be tried instead of the EZ-EFI. It seems presented as a clear competitor to the EZ-EFI system with many of the same features. I understand the practical advantages to this setup. It is much more complex to go with the full fuel-line loop route.

On the other hand, you'll be the first sucker :Brow: (err, first brave, intrepid, adventurer :laugh to try the Atomic EFI system that at least I know about. One of the reasons I went ahead with the EZ-EFI system is that Jim was familiar with it, and there have been a number of V-8 Buick board members who have been extremely happy with the EZ-EFI system. So from my point of view, it was better to spend the extra money and have a system that had brought "much EFI happiness" to other V-8 Buick lovers.

I also wanted to have an in-tank EFI pump to give this pump maximum cooling. I had heard of problems with the pump outside the tank increasing the risk of burnout, and I didn't want to risk it. Of course that makes the installation that much more complex and costly . . . . .

So, I understand your dilemma . . . . . :dollar: most definitely still doesn't grow on trees!!

Best of luck in getting Saint Nick to bring you a big-block Buick!! :TU:

Cheers, Edouard :beer

P.S. :grin: Ya' sure your chimney is big enough for that? :laugh:

 

Edouard

Again thanks for the imediate reply , I found this info over on your "Billy Goat adventures " thread, it makes mention that you have a " TSP stroker conversion to a stock oil pan"
Is this engine a stroker engine? Seen the .050 offset grind crank and 6.8" H beam rod.

BTW awesome Build-up info you provided thank you!!

 

Larry's TSP engine also uses the same stroker combination which gives a 470 displacement on a 455.

Since Edouard's engine made just over 500 hp with 448 cu. in, if you do the exact same build with a 470
figure the extra torque and power.

Just something to ponder.

Paul

 

Paul, Larry

Thanks again for the responses.

TSP I assume is Tri-Sheild Performance?

And are these stroker kits availible thru him, the reason for the question , is not much is on the TSP website.

Paul ..

That would be one heck of a engine, I've seen on LARRY70GS's signature that his 455 TSP 470,did 602 HP@ 5900,& did 589 TQ @ 4900 !!!
Don't know all the specson Larry's but still a smaller roller cam, Stg1 Aluminum Heads and a Qjet intake , may be a down on power a scrunch , but still.....
Things not to ponder but drool for!!
