[razoredge]

stock used block/lower end, stock differential & final drives, not too shaby !

[Northstar]

31lbs of boost? That's rediculous.

[razoredge]

says alot for that lower end

[FAPTurbo]

Wow... I was never a doubter of the ol' pushrod's but this thing screams insanity.

In a good way though .

I'll send it to my friend who has a Grand Prix. He's gonna love this.

The Buick GN guys have been in that neighborhood of boost for decades- some with stock blocks, some with race blocks (276CI). Now there's some incredible aftermarket blocks, can handle way more than anyone would want on the street.

[razoredge]

276 ? Whats that the 4.1 ?

on center stage II is a great block, but the on center Series II L67 is seriously sturdy too and its a common production engine

[Sixty8panther]

Hmmm... every once in a while I think it'd be super cool

to have a TT 3800 powerplant in my eventual '59 Buick.

[balthazar]

yeah; the 276 is a 4.1, but it's not RPO.

This is the baby for all-out: the T/A Performance V3800 block.

All aluminum (weighs less than 100 lb), 6-bolt cross-bolted mains, 14 head bolts. Said to be capable of between 2000-3000 HP.

I am not in any way casting dispersions on the RPO 3800, just showcasing how far 3800 fans have pushed the envelope. It's one well-loved engine family.

Sixty8: no,no,no,No,No,NO! A car that angry needs 8 angry pistons, not merely 6.

Wow ! I guess I havent been following, I think that was in developement about 3 years ago, am I right ? So its not even a real "Stage" block ?

I have dreamed of building my own midengine sports car out of one of these. Using some shapely Buick body ideas from a few decades back. But alas reality finally set in and dream no more.

Any pre 65 Buick should only be powered by a 445 Nailhead......all other powerplants should be outlawed for this use. So what if theres more torque available more recently, it aint a nailhead.

I know, I know, I know

Speaking of which, I'd love to buy this...

1979 LeSabre Turbo Sport Coupe

[razoredge]

there had been a few of them for sale around here just a few years back. Not a good era for body styling and they represent who, what, when and why Detriot began to fall from grace by not getting it. At least the V6 or small displacement was a good idea but in a car of this size ? I have a test artical I bought off e-bay for LeSabre Sport. Performance for these early turbos was not impressive. Still kinda cool to see now that they are old. B bodies, gotta love em'. Olds had a Delta 88 Holiday that had a very delicious sport interior, all plush velour, floor shift, gauges. One of them came up on ebay 4 or so years ago.

[balthazar]

razor- the T/A Performance block is brand new; pretty sure it came out for '06. I think you're right: the 276 is a Stage II block. Not up to speed on this stuff; too new for me.Of course, a pre-'65 Buick could also rightly be powered by a Wildcat 465, no?I had all sorts of allusions about building a SC 401, until I looked into the costs, which would be astronomical. 455 has to be it, I'm afriad.

[razoredge]

hmm ? scratches his feble head............. 465 ? 445 ? 425 ? 401 ? always confused me. I was thinking the twin carb 425 was a 445, must be Im wrong, its a 465 ? See the nailhead thing gets foggy due to the torque rating being the most commonly used number designation, not the c.i. Help me out............Im really lost now. I bet there was really nice aftermarket manifolds and valve covers at one time. Ive seen some nice photos, years ago. What did you do with your origional engine ? Which was what ?TA block may be that new, I believe the buzz was around a few years back on turbobuick. As I got thinking about your post on the block, I seemed to remember reading about an all aluminum block in the making. I think it will accept a variety of heads too.There was a short stroke 3 litre made for racing too but I know nothing about it. Maybe a road course engine that needed rev's and was displacement limited.

i know a guy that had one stock in a ~90 olds

a 90 would be a 3.3 corporate engine, unless its the 3.1 or 2.8 Chevy sourced 60* V6.

my 86 LeSabre has the Buick sourced FWD 90* 3.0 corporate V6, so did 86 Deltas, the 3.8 was optional in 86 on H body, standard in C body. After that the GA, Skylark, and a few of the smaller BOP cars had the corporate 3.0 until ? 87 or 88 when the 3.3 replaced it.

The 3.0 Im talking about was a Buick RWD race engine

[balthazar]

Yeah- I personally don't care for referring to Nailheads by torque ratings- it IS confusing.

'59-66 4bbl 325 hp 401 = "Wildcat 445"

'63-66 4bbl 340 hp 425 = "Wildcat 465"

'64-66 8bbl 360 hp 425 = "Super Wildcat 465"

The 2x4bbl 425 did not have any air cleaner designation (it came with a chromed AC and polished aluminum finned valve covers, and Buick did not raise the TRQ rating over the 4bbl 425 for some curious reason. I guess Buick was too stately to get embroiled in the HP war (forgetting the dual quads for a second. ).

There were 'lesser' motor designations, also:

'62-63 2bbl 260 hp 401 = "Wildcat 375"

'62-63 2bbl 280 hp 401 = "Wildcat 410"

There's still a nice selection of aftermarket nailhead appearance parts: finned valve & valley covers & air cleaners. Motor is a mainstay in the hot rod/custom world. Here's just one:

My Invicta had the 325/401 (standard & only motor available). I sold it to a guy in Florida who put it in his '64 Riviera. The trans & rear went to a guy in NY who has a fire-damaged '59 he's slowly rebuilding. Due to chassis modifications, even if I wanted to, the car could not be returned to stock powertrain (tho they say 'nothing is impossible') and at the time I started the build, the car was worth 1/3rd in #1 what it's worth today.

ah, i know you were talking about the race engine, was it based off the 3.0L stock?

i wasn't sure what year his olds was... just kinda the same body as the 88~92? regal, so i guessed

[razoredge]

The 3.0's were based on the 3.8's same bore just a short stroke. So the stage 3.0s were also short stroke 3.8's. Dont know much more than that. There was a few changes and variations to the stage engines.
