1981 Pontiac Firebird 454 Big Block V8 SWAP w/ FLOWMASTER SUPER 10s!

[@Bobthebuilder.69]

The old 454 sounds good now. The Pontiac guys are gonna be wondering why he didnt put a Pontiac 455 in it. I know 454s are everywhere so i get it.

[@SantanKGhey1234]

the 454 made 165hp the 455 made 166hp pick your poison 😂

[@Bobthebuilder.69]

@@SantanKGhey1234 lol! I have a 454 and th400 from a 70 ls6 chevelle. They were rated at 450 hp. The early 455s made alot more than 166 hp also. Maybe in the late 70s when every engine sucked because of emissions and the gas shortage. All American v8s from that era were turds

[@devynvehue5880]

@@Bobthebuilder.69that’s what they were referring to lol the cucka ones. The true original 454’s like you’re referring to are MONSTERS and tough as nails

[@Itsarealone]

It could be also that they may be a bit easier and cheaper to buy aftermarket parts for to build that power up. I would have loved a big block over my 350 in my nova

[@FirstnameLastname-pe5ib]

That torque. Bro is practically at idle, barely touching the gas and already down the street 🔥

[@CorvZ061]

Very Impressive! It's gotta be making at least 235 hp!

[@77zrod46]

Lol

[@StockTurboN20]

It can make more it’s choked up by emissions unfortunately

[@CorvZ061]

@@StockTurboN20 he’s headers, cam and intake swap away from 400hp. Big blocks can make good power pretty easily.

[@CB12345]

That is still weak for a car like this. But I'm glad be is rebuilding it to be a better machine to drive.

[@StockTurboN20]

@@CorvZ061 yes they can I knew that already I was stating this particular model year for any muscle car is choked for emissions which is dumb but hey

[@coolhanddruid]

0:21 You smashed the pipe that bad for an E brake cable, that still rubs?

[@hemihead4269]

My 77 trans am had crate 502 installed and i had Flowmaster 10 installed. Topped it off with 750double pumper on a eldebrock hi-rise. Iskidiman mid range cam and she was a beast.loved the lope especially when she was cold.

[@The_Cyber_Nomad]

Sounds good, but the crushed pipes look horrible.

[@Itsarealone]

It's the damn speed bumps and low hanging long tubes, my 74 Nova had the same issue. I had to snail crawl over most speed bumps to avoid hitting my long tube headers.

[@ShelbyCorGT500]

Smashing the pipe for the EBRAKE is such $H1T work. Seriously 4SS !!!!!

[@SantanKGhey1234]

454 cubes and 165hp - The best of GM right here

[@BaileyHolt-f7m]

yeah that was after the dern epa made them detune it.

[@Mr.Hemi345]

I had one just like that in high school but mine had a 350 Chevy in it

[@monikhushalpuri]

As soon as I saw it had no h pipe or x pipe and was just true dual, I knew it would sound good despite having flowmasters, great job

[@R_86s]

Wow this thing is LOUD 😮‍💨

[@msh6865]

I'm a Dynomax fan so, Ultraflow's are my choice. And those 2.25" tailpipes are restrictive. Go 2.5" at least! Having said all that, I do love a big ole 454 in a Firebird or Trans Am. Nothing against the Pontiac mills, they're good. But, making reliable power and torque with a big Chevy is sooo easy!

[@GS-jk4cs]

It sounds bad azz but the overall exhaust is subpar. Crushed tubes? Come on!

[@MidwestMotor]

My mom bought a brand new 1979 Firebird V6 when I was in elementary school - even then I was SO MAD she got the V6 but it was my frikin dad who thought he could make a difference during the oil crisis to get a 6-banger. I went with my mom when she test-drove a V8 Firebird. Still mad to this day - because I got her Firebird when I was in high school - I was going to do a V8 swap just like this! But I ended up getting a 1989 triple black Trans Am with the 5.7!!! NEVER should've sold the '89!!!!

[@jessiehardin8275]

That's my friend Jr car and he has had it for a long time

[@CB12345]

That is a good thing. I'm honestly glad there are still some people holding on to their older muscle cars and trying to rebuild them up.

[@Akron2PDX]

That sounds amazing

[@oscardeneergaard2132]

Sounds really great with flowmaster super 10 👍

[@johnwyatt27]

Ol Formula had one of these had a 403 Olds wasn't the best but was a fun car to drive

[@KsKaylor]

Beautiful sound, just get that engine tuned up and you’ll be good to go.

[@HoldPublicPigsResponsible]

Needs a tune big time. Wow

[@ynb3a9y4life]

God bless BIG BLOCKS !!

[@joe.olivet]

Nice work! 🤘🏻😎🔨 Sounds pretty good.

[@billknight5578]

That sir, sounds badass. I've ever heard a Super 10 on a big block. It sounds so much deeper and just all around loud. It's awesome, great job, fellas 👏👏👏👏

[@exhaustaddicts]

Right on!

[@funieman1]

Nice sounds real healthy 🔥🔥

[@Dave-captain]

nice sound

needs more 455 HO

[@frankvitullo4925]

I’m sorry but the quality of this job is just horrendous. Almost like a blind man did it. Exhaust to me is like the finishing touch of any build that I do. If I saw a job like that done under one of my cars I would go nuts. I feel sorry for the customer. He seems like a nice guy but I would have never paid for a job like that. I live in Toronto Ontario Canada and everybody here knows Hot Rod Scott’s exhaust. I’ve been going to these guys for 20 years plus. Best exhaust shop in Ontario. The Nasty Cartel!!!!

[@chrisb-br5nx]

As an actual blind man, I almost take offense to this ha ha

[@hutchinson54]

454? Must be a Chevy motor since Pontiacs/Buicks/Olds had 455s.

[@Unhinged88]

Sucked out 😂😂😂😂

[@77zrod46]

Won't be buying thise mufflers. I hate it when a big V8 sounds like an overly loud raspy V6. Guy at work put a catback on his Camaro w/a 6.2 and sounds like crap, or like this.😢

[@matthewandphee3649]

That sounded like total crap.

[@StockTurboN20]

He needs to retard the timing that’s why it runs like crap and also it’s too raspy

[@CB12345]

​@@StockTurboN20Thank you for this information. I am thinking about getting a retard system myself.
