Here's a 1982 4.1 BUICK V6 I have tucked away. Going to build it eventually. 252ci is the stock displacement. Made from 80 to 84. Pretty rare these days.
Yep, they came in pretty much all GM full-size and mid size cars in them years. Olds,Pontiac,Buick and Cadillac used them. But most people ordered the V8s in those cars like the 307 Olds and 305 SBC. Those Olds diesel 350s popped up in a few of them. Caddy had the 368 available till 82, then went to that crappy 4.1 liter V8 caddy engine. The 4.1 BUICK V6 was a better engine that that 4.1 V8 Caddy. But in a 4000-5000 lb car, the 4.1 buick was a slug. They ran ok in the Regals tho. They definitely have hotrod potential too. Smokey Yunick messed with them in the early 80s and got impressive results.
Cadillac also made a 4.1v8, often confused with this v6. I've never seen the Buick 4.1 V6 in factory turbo form, they never were equipped this way as far as I know.
@@thereluctantgearhead4544😂 the 4100HT crack pipe engineering at its finest. 😂 I think I remember the 4.1 Buick serving as a stop gap while GM rushed to introduce smaller displacement, more fuel efficient V8’s. That’s when the catastrophe 4100 was unleashed to the masses lol. Aluminum block, iron heads 🥴
@@lynxstarautomotive208yep, those Caddy 4.1V8s were junk. Did come with chrome valvecovers tho. Always thought that was kinda cool. Rest of the engine sucked. Only Caddy engines I ever liked was the 472 and 500 inch versions.
That must be what the TA Performance GN aluminum block with a 4.00" bore is based on? Top that off with a set of TA',s aluminum v6 heads they sell that flow IIRC as much as 300 CFM. That's enough to support 450 naturally aspirated HP. Add some turbo boost and the block and crank is the limit but probably will handle 800 HP I would guess?😎👍
Those Stage 2 headed 4.1s were 550-600 hp NA in Busch cars. Turbocharged Indy Buicks were over 1000+hp back in the mid 80s. Think they were around 3.0 liters. Those heads flow alot. Ports are huge. There was a few 2000+hp Buick GNs back in the day. Kenny Dutweiler had one running low 7s in the 1/4 30+yrs ago. Buick GN vs Mustangs was a big thing back then. They used to have big shootouts between them at Memphis.
The Buick Stage 2 heads typically flowed 330+cfm. Pretty rare heads these days. The intake that goes with them was a work of art too. There are people selling old outdated NASCAR and Busch GN parts for penny's on the dollar. I found a bare pair for $1500 bucks. Believe they are from early 90s or late 80s.
@@itseithergonnaworkoritaint7852I've seen one pair of them heads in real life off of an engine. Pretty impressive. Not many people would give the real numbers. Highly competitive world. But a few of the engines have ended up in drag cars. The Buicks dominated the Mustangs in those shootouts. In the Busch cars, they competed against other similar V6s. Chevys and Ford's & Mopars were all represented. Ford had a hell of a V6 racing engine too.
There's a video out there of a Stage 2 V6 on a run stand. It went into a drag car. Believe it was around 600hp NA with a 1050 Dominator. 8800rpm unit. It was an ex Busch class engine. Busch did away with the V6s in the mid 90s, went to low compression, restricted NASCAR V8s. Bill Elliot was gonna run a Buick V6 in NASCAR against V8s, but NASCAR didn't want people to see how close that V6 was to the V8s at the time. Un restricted Buick V6 racing engine would run with the restrictor plate 358ci engines. They were pretty much magic. Especially 30-35 yrs ago.
Your just full of surprises! Haven't seen one of those in a day or two! 👍
Pretty rare unit. Gonna build it one day.
@@thereluctantgearhead4544 That'll be a cool build!
@@my357mags They definitely have potential.
Neat peace of history
Cool stuff for sure.
Tough little engines really.
I remember seeing one of those 4.1’s as a kid in an 81 Cadillac at a salvage yard.

@@thisisyourcaptainspeaking2259Nope, 4.1 BUICK only came with a 4-barrel. This top end came from a 1985 3.8 GN. Block is a 1982 from a Riviera.
looks decent cleaner than my 64 Special V-6😝
Be a cool swap into a 64 Special. Definitely give it some pep.
This engine been sitting over 25yrs.
My daily driver is a 231 g-body with the 4.1 intake manifold.
Those stock Q-jet intakes are pretty rare. Good piece too.
I sold the 4-barrel intake that came on this one. Wish I would have kept it.
@@thereluctantgearhead4544 Really woke up the 231, maybe you've run a 4bbl intake on one.

So you're talking what the NASCAR v8 heads flow, around 400+ intake CFM to get that out of a 6 banger NA.😯😎👍
