318 build #2 "cost minded" for the '74 Duster

-
Speaking of tires, there is a lot to gain in terms of mileage with the right ones.

Since you are doing a regrind, maybe talk with Oregon about a dual pattern cam to help crutch the exhaust with your stock manifolds. Are the manifolds 318 or 360?

Whoops never mind about the regrind comment I see you have a comp cam already.

If you do nothing else to help compression at least run the Mr. Gasket .028 head gaskets.

Also another question- is your converter lock up or no? Obv 904 l/u would help mileage.
it's non-lockup
 
how much does the dooster weigh?
It was 3160, no driver, no spare, 1/4 tank of gas. But since I've swapped the 7.25 rear for 8.75, 14" steel wheels to 15" steel wheels in the back, plus I went to a heavier duty drive shaft. I would think we are easily 3200+ in the same conditions.

rear tire size i forget
 
All Im gonna chime in with is 13.9s with a budget 318 with no headers, stock converter and 2.94 gears out back? Good luck Im calling a 19 second 1/4

Well, the 318 that's in there went high 14's.... hoping this engine is more efficient :)
 
My 10year ago 318 in my duster had Hughes 214/216 regrind, 302 heads, 600 eddy, headers, & 3.55s ran 14.2 and almost 17 mpg driving 180 miles back from the track.

Will you be using an AFR gauge for carb tuning?
You can cruise pretty lean w th right metering rods in it.

I do not have a AFR gage. Nice run with your 318 you had in your Duster!

well for context. My hot mild 360 with a 4 barrel, headers, very tame ported heads, a wide ratio transmission and 3.23 gears went 18 seconds in the 1/4 on good tires so there's my proof/reasoning it wont go 13.9s in a 1/4. I had more cubes, a good carb, better exhaust system, ported heads, and steeper road gears than yours and it did that time. A 318 of lesser value will not be faster under any circumstances UNLESS you are spraying/boosting it.

in what vehicle? Not being sarcastic at all, but that's really slow for your combo.
 
my engine in a buddies pickup that was even on a diet. 95 dodge dakota swiss cheesed and gutted down to 3,100 pounds
ok, thanks. Again, the current 318 (the original low dollar 318) in the car has gone high 14's at almost 95 mph. We are hoping this 318 will be more efficient and out perform what's currently in the car and .... at least on paper... it should.

1968 dart 225 slant six 145 gross hp 2930 lbs without driver goes 18 flat stock
at 3100 a 360 4spd 3.23 with traction should run 14.5 backwards
did he tun it off at a 1000 feet?

no he buried that pedal. I'd like to see your time slip though
 
you woudnt
stock 318 2 barrel weighing more then that run high 15s
do some research
quit while you are behind
hey im not going to be offended. But I doubt a budget 318 with those gears gets a 13.9s. Should I mention that Ronnie Sox tested a 340 Duster with 3.91 gears in 1970 and ran the 1/4 in 14 seconds? Is that good enough research for ya sweetheart? :thumbsup:

the op has posted his time slips and videos just because you have the slowest v8 mopar at 3100 lbs on the planet doesnt mean much
not really you should know 18 seconds is so slow for 3100 lbs you shoudnt even mention it unless 4 plug wires are crossed
@3300 lbs 18 flat is 129hp or 110 rwhp
74 360 duster 15.2 stock 3400 lbs
68 318 2 barrel 16.0
enough of this foolishness
carry on

you're talking about a basically bone stock 360 with a gasket kit, headers that i found in a barn, an old 4 barrel intake, an old but good edelbrock carb and heads that i spent about 3 minutes cleaning up casting flaws on with a wide ratio 4 speed and 3.23 gears. Why in the hell do you think we swiss cheese and cut as much weight as possible. It was the equivalent of David Freiburgers Cheap Thrills Dart. You are really really really reallyyyyyyyyy arguing that 2.94 gears on a budget 318 will put it in the high 13s lol
 
@318willrun, I like what you're doing here, I'd like to build a similar engine, I have a nice 318 Magnum short block. Since I don't have a cam like you did, I was thinking of getting the stock cam reground at Oregon Cam. They suggested the #1312 with 206/210 @ .050”, 262/264 adv, .475”/.507” lift(1.6:1 rocker), 112 sep as a mild street performance upgrade. With stock heads (assuming 58cc), flat tops and MRG11216 gaskets, I calculated 9.8:1 with no deck machining. I think that sounds like a reasonably fun combination topped with an Edelbrock air gap and nice double pumper. I'll be curious to see what you're results are.

he already did it with a 360 or cant you read ? or watch a video
4 plus seconds quicker then the same combo you just listed with a single track rear end
some can do and some cant
freburger runs 12s with his junk stuff not 18s
ronnie sox ran 100 mph trap speed when he ran 14.0 thats a 13.5 et@ 3400 3500 lbs with traction

until the day comes I wont be a believer in it. Im fine to be proved wrong, it happens to everyone. But Im not gonna buy it until I see it

Oregon Cams won't steer you wrong! I think you have a nice build

And I'm fine with that. I may come up short, and I've stated that already. I did go 13.9's consistently with my 360 Duster, no headers, stock converter, stock heads, 2.45 gears, and a real small cam (smaller than a factory 340 cam). But that was a different project and test and that car has had some changes since, now runs 12.9's. By the way, I appreciate your honesty in stating what you actually ran with your 360.
 
My 73 Duster full street car with buckets and other weight adds like rear window louvers, speakers with heavy magnets, Demon scoop, and DC trunk spoiler went low 9's in the 8th mile.

Fresh LA 360, stock 904 with 270-ish DC cam, 360 manifolds with 2.5" duals and 3.23 SG 8 3/4.

IIRC that's a low to mid 14 sec 1/4 mile.

EDIT- also had iron 4 barrel intake, and working AC.

I want to say 89 MPH.
