Hehehehe...1970 Firebird Formula with a very built 455 with a .540 lift cam going into headers, X pipe, and Flowmaster Force II exhaust kit.

Anybody else got that sound on a ThirdGen? Hehehe

 

hell yes i do. I wish i had a car but anyways, last night a corvette stingray passed me and it sounded something like that. I felt the vibration in my chest. it was awesome!

 

mine kinda sounded like that with open headers..

 

Sort of like that....... A bit distorted, but you get the idea.....

Sound clip of my GTA

 

I just heard a car today at the shop and holy crap it was mean sounding. Front of the car was shaking at idle hehe nice solid lifter cam in for that crisp exhaust note. 454 that runs mid to low 11's on the motor and low 10's on the jug in a 70's nova

 

Pretty good. I have heard better though.

 

Your exhaust clip is one of only 3 i have saved and listen to religously LOL. I was looking for your name early just to tell you: you have the most bad *** sounding car on this board.

 

Mucho thanks for the compliment ! I get many compliments and questions on what all it is composed of from people that hear it in person as well. I have to say that I am extremely happy with my setup ( aside from wanting to go with some Hooker LTs in the future...).

FYI for anyone wondering, that is the Edelbrock TES flowing into a 'Test Pipe' and out through the Flowmaster American Thunder 3" cat-back with dual polished stainless 3" outlets. See my site for more details on the engine and whatnot if you would like....

 

there is a 427 chevelle around here that sounds like that. You get much props!!!!:hail: :hail:

 

mine sounds kinda like that. hedman headers into 3" straight pipe cat and 40 series flowmaster race muffler. its pretty damn loud.

 

Ah soso, It sounds fairly mean because of the big tube headers but at wot dosent sound any meaner then my setup on the bird. That car sure does take a long time to wind out, my truck makes that car sound weak but I do admit its got the truck beat at an idle.

 

Matt87GTA...where did you get the 3'' american thunder catback??? ive been looking for one but can only find the force II for 3rd gens,.

nevermind i found it at summit.

 

riiiiiiiiiiiiiiggggggggggggggghhhhhhhhhhhhtttttttttt

 

that gta is bad *** :hail:

 

it ALMOST sounds as radical as my car but not quite....mine has more of a stutter to it. sounds good though. nothing sounds as good as a "Potent Pontiac" hehe

 

Sounds like it was recorded in a tunnel and it doesn't idle very well. I enjoy having my car sound stock at idle. The lift numbers on a cam are the least important, doesn't have anything to do with why it sounds how it does. 1970 is not third gen.

 

Last I checked, I never said 1970 was a ThirdGen...The last thing this board needs is stuck-up, too-good-for-you jackasses. ****, since when did I ask for a smart *** comment? Everybody else seemed to say something worth a damn...why can't you?

 

amen brother

 

Here! Here!

 

What RPM are you idling that Hot cam at? 650?

http://home.attbi.com/~markolc/xe230-236.mp3 That's my cam at 900 RPM. it sounds better not that I have a test pipe but it used to sound like that.

 

OHHHHHHHHH How I wish that was my car LOL. That's Scott Schering's car...he's the webmaster at Pontiacs.org, and is a super cool guy with one BAD *** Firebird. He just bought a 73 TA that he is now in the process of restoring like the 70.

Not sure what he's idling at bro. I LOVE the way your car sounds...LOVE it.:hail: :hail: Im all for the big pipe, big cam hollow sound that sounds like it could jump up and punch you in the chest. What kind of engine setup are you running?

Im thinking about just keeping my 79 Trans Am the way it is, and saving up for a First Gen Firebird to build up as a street rod(built 455, of course) since I can't afford my favorite car, the First Gen Camaro.

 

LT1 350, Hooker longtubes into a custom dual muffler exhaust, CCXE 230/236 cam, ported stock heads.

 

OMG!Metkiss that is like music to my ears.I liked it sooooo much that I saved it to listen to over and over and over.....you get the idea:hail:

 

Listen to Markolc's soundbyte too...Now I have 3 soundfiles saved that I listen to alot LOL.

 

.

 

I can't remember exactly, as I am always playin around with the PROM settings, but I think that is about a 650rpm idle - maybe a bit lower like 625rpm. That clip is a bit distorted as the mic on my laptop is a complete POS, but that is about what it sounds like.

Yours sounds very nice as well! I gotta get me some LTs.........

Thanks guys, I really appreciate the kind words .

 

Sounds just like my dad's 67 GTO.

 

Whooa there buddy, little discontent? You have absolutely no reason to say that to me, unless some sad personal issues make you feel the need to. If that's the case I'm sorry. I don't mind, but grow up. Attacking someone on the internet is worthless. Sorry if you take what I said the wrong way, but you needn't assume so much or lash out at me.

I'll forget that last sentence you wrote for now, but if you'd like an explanation I'd be happy to give it if I stumble over this post again.

 

I big phat cam (230+) along with an aftermarket exhaust with headers and no cat will produce a very similar sound. The key to that sound is the cam. My car sounds very similar and I have the Flowmaster Force II catback (FMFII). The thing here that you guys have to remember is that it's the whole car that produces this sound. I had the FMFII on my car stock. I wasn't impressed. I gutted my cats. Wow. That sounded a LOT better. I put headers on. Holy crap - sounds even better. Put a cam in Geezus. Way cool. Put a huge cam in. HOLY CRAP! Muzak to my ears. Now I'm putting long tubes on. It's going to be heaven on earth.

Sounds awesome.

 

Love the idle.
