Hey everyone i am new here
I recently bought a 71 plymouth duster roller no engine or trans
I plan on building a mild 318 la that is choppy and has good torque and pep for the street and maybe some strip along with a 46rh trans and 3.23 or 3.55 gears
Plan on adding
Long tube headers
Edelbrock Dual plane intake
Holley 650 carb
Keeping the bottom end stock
The cams I've looked at
Edelbrock #7177 RPM
Comp cams xe268
Summit 6901
Ive heard of the hughes whiplash but i plan on putting that in my 81 d150 would like to have a different cam in my duster
I want a good lope and a little more power is the eddy cam good? Really like the sound but power wise is it good for a daily driver?
Any help is much appreciated!
Yeah and we all built those low compression overcammed engines too. Thing is, they sounded great, ran pretty good and were dead reliable. Probably just what a 19 year old needs.In a more serious note,, We have all been there. 19 years old,You will make plenty mistakes in this hobby.
God knows I have. It's good to see some young blood 'round here. Better than most kids these days.Keep us updated on your progress with all aspects of the car and build.
As to the cam;Best cam for the street........
Any help is much appreciated!
Yes just watch how terrible a low cr 318 with factory stall and highway gears goes.
With mild cam, 272/272, Lift .454/.454 110 IC 62*, mild porting, 4bbl and duals.
Look at all the time spent under 3,000 rpm, felt like forever.
I was being sarcastic towards AJ book 318willrun's car is exactly what AJ says not to do or it will be a slug compared to stock, which obviously it isn't.You really think so? I thought it was fairly responsive "for what it was".
Normally I’d razz ya a bit here calling you a 318 hater, but yea, with an inexpensive 5.9, instead, miles ahead.an 8/1 318, with a headgasket change from 020 to 039, which is typical, brings the Scr down to 7.7.
At 800ft elevation, with the stock cam at Ica of 48*, this is predicted to make 129psi CCP.
Put a rowdy cam in there with an Ica of 64*, and this falls to 112psi, and just like that your 318 feels like a slanty, until it gets up on the pipe, which may not be until 4000 rpm, and just after that the 318 hits the wall created by the heads.
So then yur looking at a powerband of from say 3800 to say 4800.
this is a bad idea right out of the gate.
Such an engine would need at least 10.0 to be fun. But that cam is way too big for the heads anyway.
Roll it back to say an ICA of 56* and a Compression ratio of say 9.5, and now you got a low-rpm torque machine.
Anything more is gonna need lotsa dollars to make those heads work, or just get some better heads.
To get to 9.5, the chambers gotta loose 20cc, so first up, the factory slugs gotta go. Second up, open chambers gotta go.
And Thirdly, it's not likely yur gonna be able to run the 039 gaskets.
To get to 9.5Scr, the total chamber volume has to shrink from around 97cc in stock form, down to ~77cc. with special attention paid to the Quench.
Or you can just start with more swept volume in the first place, seeing as it seems your roller has not yet got an engine.....
In about 1975, I installed a 318 cam into a 340, and bolted the 318 top end onto that, stuffed it into a 65 Valiant wagon and had a killer street machine. I was 22 years old.
340s are getting harder to find, but I can see a 5.9 in your Duster, in a heartbeat.
Somebody had to say it.
You can install a whiplash into that, install a dual exhaust, and just drive it. The 5.9M is big enough that even if the pressure drops to 140psi, that is not gonna hurt real bad.
First intelligent thing you said in months.I was being sarcastic towards AJ book 318willrun's car is exactly what AJ says not to do or will be a slug compared to stock.
Most aren't running standard transmission.> If you want power at sub-3000 rpm, yur gonna need pressure at those rpms. If you don't have pressure/power at those rpms, then don't drive at those rpms; either get a high-stall, or sit back and wait for the power to arrive.
As for me, with a manual trans, almost all of my street driving is at under 3000 rpm, cuz my engine is directly connected to the rear tires with no slipper device in between. So my engine has to make gobs of power at those sub-3000 rpms.
Your advice is tailored to your driving style, wants, needs. (which is fine but doesn't mean it's universal)>For a normally aspirated engine;
Compression is heat, and heat is power. So my engine thrives on pressure.
>For a streeter, 99% or more of it's life, will not be spent at WOT blasting down the track.
> The vast majority of the time it will idling down the road at under 3000 rpm.
> Most streeters with automatics will be running 3.23s or less, and stupid-low stalls.
>Most of the time will be spent in "drive".
> Most streeters are somewhat concerned about fuel economy and the cost of fuel almost never goes down, so in this situation, Cylinder pressure is paramount.
> My advice is for this type of guy, and this type of car.
Betting most hopping up a 318, are more in this end of the world.318Willrun is in a different world.
Typical for the 318 hater who thinks his **** is the best and only way to build a streetee engine.ah, i see we're right on track for page 2
>ditch the 318 and get a 5.9
>AJ telling us all that we don't know **** and that anything but his combo won't make enough power to pull a sick ***** off a piss pot.
>low key sideways remarks
i expect the discourse to be at least double this by sundown or i shall thrash you all about the head and shoulders with a well used fan belt.
carry on!
Hehehe. I’m younger than your damn tires!IDK, maybe you geriatrics just need to get your meds changed.
it's when "perfect" becomes the enemy of "good enough" and honestly, most all of these engines are just fine and dandy at "good enough" and most owners will be more than happy with that outcome.Typical for the 318 hater who thinks his **** is the best and only way to build a streetee engine.
After all being 71 means you know everything.
What ? 2 pages and no one said...
Turbo Charger !!!
Pssshhh… I’m thinking eBay turbo, megasquirt port injection and a 175 shot to take that teener out of boat anchor status.
