tunnel ram

That's the beauty of these cars, they're so simple. I'll cyber spend $1.63 of your money. I went to the office depot had them Google (in my case) "1973 duster wiring harness" and asked for a large color 18in by 2foot copy and a standard size b&w. Yup $1.63. Funny it's only like 27 wires? POoooFF ! You are an electrical Wiz !

You know I wrote something to that effect and erased it but I do like the Edelbrock for the hobbyist and the obvious is it's easy to work on and once set seems to stay that way. I feel that Holleys are better to aek out max horsepower but a little bit more finicky has been my experience witch is very limited with them.
 
100% J Par. The Edelbrock gives up a little bit of top end & the ability to be super dialed in. That’s it. Jet it, set it, forget it. Your done.

I like holy's just fine that's all I used as a kid. Just trying to get 400 hp from the engine. I'm planing on a long trip to washington state next summer with the scamp my cousin has a 71 charger 440 6 pack were going to car shows and the track

can I ask why "400 horse"? The reason I ask is that seems to be the most common number in the world thrown out ... "400 horse". Everybody built a 400 horse 350 for their Camaro.... Or their pick up has a "400 horse" 305 in it. Not 375 hp, not 425 hp, but 400 horse. Even when I was in high school, my stock 318 with 2.76's was beating "400" horse motors... LOL. So I was just curious where the number came from..???
 
@318willrun

LMAO, that was the number everyone threw out there! Even when I was making more than 450hp, it was always 400hp. Then (LMAO) everyone wants to know what is in it. (Enter tall tales and lies... LMAO!)
It is also said that 400hp will get you going presto fast, if the rest of the package is right.
 
"10 second car" is the one that I always hear. 10 times out of 10 they've never been in one let alone own one. And without question don't have a clue at what it takes to get a car to be able to take one 10 second pass let alone doing it consistently.
Ever since the first "fast and furious" I like that one but..... it gave the millennials the idea that a consistent ten second 4 cylinder car is easy common place LOL.

LMAO! No doubt!
Hint to a 10 second street car... build a 9 second track car and make sure it hooks as well as possible on the street.
LMAO
 
"11's" seems to be the common statement I hear. 302 2bbl in a Granada..... them: "She runs 11's" LOL me: "should have no problem with my 15 second 318, want to run em' "?? them: "Naw, I floored it out of town and the ring and pinion let loose, wait till I get 'er fixed".... :D

because I have a led foot and I haven't been in a fast car in 40 years. ok lets say 450 hp I'll just put my seat belt on.
 
Are you opposed to making upgrades in stages? Maybe try just swapping the cam for now, see how you like the power; if you want more then start looking at other upgrades. Like others said, based on what I see from pics of your engine it should top 400 HP at the crank with just a cam swap... 175 psi is pretty high cranking compression too.

fishmens67's meant by detonation, does the engine ping/knock at all under heavy throttle?

not at all when I went from a 600cfm carb to a 750 cfm carb no problem it Idols a little more lopy but likes the bigger carb when off idol. pistons are flat top even with the block on tdc. and I think I'll do a cam change first. Iv'e got time to play with her just don't want to go to far and blow the bottom end. I'm gonna sell the nitrous set up I have only used 2 fills on the 10 lb bottle with small jets. and yes I did a good search on using nitrous before I used it. just to much pain trying to get race fuel and wait for the tank to heat.

Hey just because these ladies don't have the cojones to put a dual quad tunnel ram on their car doesn't mean you shouldn't too?! I did it, with a low compression 318 and dropped a half second at the drag strip right in everybody's face, when they said I couldn't! just like they're doing to you now. No I've had a dual quad setup since I've started this motor and haven't regretted sense and love it just like what's his name there said it's badass and always will be and always was! I say do it! And why the heck are you letting these guys call your 340 low-powered?

I don't think the internet is going to help you build a reliable 450 horse 340.
it can give you a recipe, but there is more than just putting in a big cam and lining up the dots.
good luck I hope you don't poke a hole in the piston or rattle it to death.

yea me to. I'd be not happy
 
400/430 is a lot more streetable with a 360.
400/430 with a 340 is gonna burn a lotta gas on the hiway, and an overdrive is not thaaat much help.
400/430 with a stroker is probably what you need
And then there's supercharging.

But if you lower your expectations just a little, to say 330/360, that's a whole new world.

But if you knew how heavy you were gonna be on the start line, and how fast (not quick),you wanted to go, then it's just a bit of math and like magic, there's your target hp number. Then after that it's just money. And a lotta money goes to making the car ET according to its mph.
If you start with an ET goal, to run with a street suspension, then it's cubic dollars: or could be.

Here's a fer instance;
Suppose you scale at 3600 pounds, and you have a 400 hp engine, the math indicates 3600/400=9pounds per hp. and the chart says this will do about 111mph with an automatic. The same chart says this should go (not will go), 11.9 ish, with SuperStock suspension. Your street suspension could drop that from 1/2 to 1 second slower, or even more.
Now, it's gonna cost a lotta money to go 111 in that tank, and it's gonna cost a lot more to whittle the time down into the 11s. So there's no sense of talking about 11s with a 340 unless you got a lotta money.
Now, my wife says I come off sounding condescending all the time, and that is not my intent.I'm just laying it out there.
And we haven't even talked about the maintenance on an 11 second 340 car. This is really not the car you want to jump into and drive a thousand miles.
And , then there's this;
Put a BB in there and 11s get easier, and that car could be the one to go touring with, cuz it's much less stressed. You can run less TC, and less rear gear, and it WILL respond to an overdrive.
And the best news is that it costs about the same money to build 400 horsepower with either engine, ignoring the cost of procuring it. The 440 might actually be less, cuz you could do it with factory iron heads, whereas the 340 is gonna need some more serious heads
>But now look here, suppose you just want to break into the 12s, like 12.9 with street suspension cuz you don't want to spend the $2000/$3000 or more on the SS suspension. So the chart says a 12.9 street car needs to at least, at least, be a 12.4 race car so that, at 3600 pounds is 360 hp, see now that's doable fairly cheap.
What else is doable is to remove the P/S and P/B and take a total of 200 pounds out of that car. That's doable, and you won't need those on a tour, anyway. So now you're down to 3400 pounds and 340 hp, even easier. Now you've got a reasonably streetable 340 car.
>Now you go and put the bare minimum traction controls on there, like SS springs, sticky tires a traction aider and some lightweight wheels,and the right rear gear, and so your 60ft comes down, and maybe your ET comes down .3 seconds.Well the flipside of that is; if 12.9 is fast enough, then you can take another 20 hp outta that 340 and have a 3400 pound/320 hp, very streetable pkg. This is just a basic hi-comp340 with headers and a hi-flow exhaust with maybe a one size bigger cam.
Maybe you already have this engine, so you could be in the 12s with just the diet and the rear suspension mods.And best of all, this level of performance, after the tune is in, will run forever on nothing but normal routine maintenance.

I can do 400 HP with a 340 falling off a log. You'd have to try to make less.

A proper valve job and porting, 11.:1 compression, the correct cam and intake with a GOOD header and 400 is stone easy.
