BULL****!! There is NO ****in' way that Hemi has the stock exhaust! I DEFFINENTLY believe the performance aspect, regarding being stock, but there is NO WAY IN HELL that the stock exhaust is on it! BTW.. what sized block is that? 426, isn't it? Or no.. I don't remember..

And when I said this..
LOL, I bet they will be ****tin their pants, just like w/ that Challenger on 2-slow 2-gay! lol.
I was regarding dropping the BB into one of your 'Marrows!

Ok guys, enough of the hijacking

For the question at hand, I also think you should go the junk-yard 350/383 route. BUT... if you persist in wanting to keep the 305, here's what you can do...

Cam: LT1 cam. Used it'll cost you $30. That's $30 for around 20 hp
Heads: See if you can find some Corvette L98 heads. They flow great, plus they're aluminum
TBI: I guess you could go Edelbrock. I don't know too much about that model, but what you COULD do that would be cheaper, is take a TB off a 454.
Intake: I believe you can get a Performer RPM intake manifold for the 305 TBI, if so, do that. As far as cool air, I don't know what you have for ducting, but you can always go open element. I noticed a SOTP difference when I put one in my old Camaro.
Exhaust: Really doesn't matter too much here, as long as you free it up. Any brand shorty headers, !Cats if you can, then a catback.

After all of this, you're gonna need a chip tune, especially after the Cam and 454 TB. But you'll be WAY over 250 hp. Probably closer to 270.

Now, you're going to have the power, so the next thing you want is to get it all to the ground. Don't forget suspension mods. Tranny mods do wonders too.

Hope all this helps.

Speaking of LT1 cam, I have my stock LT1 cam, rocker arms, springs, and push rods in my dining room sitting in a box (they dynoed 292.3 rwhp w/ just bolt ons and shorty headers, through a cat). If you're interested, email me zcarmenb28@yahoo.com

i myself am not a fan of our friend nitrous oxide, to me its cheating..lol.....only form of forced induction i like is s/c cause they run much cooler than turbo's and are simpler.......
Turbos are not that complicated, they just require management to control the boost. I personally think its cool to be able to increase boost with the turn of a ****. I dont understand why people consider nitrous cheating, is it because you can get a setup for less than 25% of the cost of a supercharger? So, if I put together a purpose-built engine with low compression, a low rpm peak, huge exhaust valves and ports, then put a 250hp nitrous setup on it, that makes me a cheater?

no, cause like you said, its purpose built, the cheatsers r the ***** with the stock engines with 125 shots, thats retarded, if your BUILDING your engine with low comp, and so on THEN u do the nitrous then its all good......what pisses me off is the lil crx's with bone stock motors with 125 shots of nitrous....THATS cheating....in the crx's case, its the *****'s way of power........and still im not a big fan of nitrous cause it only gives you top end power, i myself dont need 250 extra ponies when im doin 145 down the interstate, i dont have a drag strip so i have no need, what i DO want/need is low end torque, something nitrous will NOT give you....this is when u need a supercharger, yes it takes power to turn the rotors in the s/c, but u have little or no lag, like you do with a turbo (turbo lag), i got nothing against a turbo, sh*t id like a turbo in my 88, but its not my 1st choise.....

How do you figure its topend only?

You can tap it off the line if you like, at 30 MPH, at 60...whenever you want and for however long you want. Its inexpensive, and excellent for those that want the power of a supercharger without the constant fuel economy loss---and for those who don't want to deal with custom-fabbing a turbocharger.

inexpensive, it CAN be, it depends how much u use it, filling a bottle isnt cheap, trust me, i almost put nitrous in my s10, and u cant give it juice at low rps or *boom*...if u dont believe me, feel free to install a 700$ nitrous system in ur car and push the lil go-baby-go button at about 1100 rpms a couple times and let us know how many pieces of your engine you come back home with.....

i did alota research on nitrous oxide when i was interested in putting it in my lil truck, i know the lilitations of nitrous and the consecuiences (sp).

Cheap 305 combo:

Stock shortblock

97 305 Vortec heads (available, mostly considered boat anchors but they work well on 305's). Get the springs upgraded and the necessary machine work done to get them to fit.

ZZ3 camshaft

Edelbrock performer RPM intake

650 Holley or equivalent

1 5/8 headers

This combo should make close to 300 HP.

Just a pipe dream I had if I buy another 3rd gen that has a 305.

My friend hits nitrous at 3K in first, and holds it until the race is over. He's had no problems, and has been going through a bottle every other week (during the summer) for about two years.

Wow.. that is just SOOO ****in' awesome that BONE STOCK, a car can both give you a hard-on, and make you **** your pants, all at the same time! Even the Cuda's, etc, w/ the 440 sound that nice?
My uncle used to have a '69 Charger R/T, 440 4bbl, 4-on-the-floor.
He also put a set of Hollywood Pipes on it. (I am thinking that only the slight older than 16-year-old-crowd knows what Hollywood's are, as I have never heard them, just OF them.)

Yeah dude, this cuda came to the show with just an aggressive cam and stock 440...and that bastard had everyone's attention. It was SO menacing with the slight shudder of an idle... Angry/powerful sounding. I love true american muscle.
