I put that same cam and springs in a magnum 360. It's got long tube headers, edelbrock air gap, 650 brawler. It runs good! Great response right off the crack of the throttle and good pull all the way up into the rpms a bit. I look forward to seeing how it does in your 318.

Really!!! Your going to make us wait the whole winter!! I wait to see how it turns out so bad. Sorry but I think headers are going to be a big deal in this. They help so much with the flow on these motor. I think your going to kill the 20 mpg with this cam.
Interesting, you just made me realize this is something I had not considered with my magnum build I have coming up. Will you have to go back to an LA style timing chain cover than to run a mechanical pump or is there a better solution?
Another great video sir. I'm impressed with the way you do things, and how you try to go fast, yet get good fuel mileage at the same time. It can be done, and you have proven that with your van. Thank you for sharing sir.
Recently I have been watching some of the other channels and comp cams with flat tappet lifters has turned into horror stories, after just trying to break in cam and lifters completely warn-out on break in. Causing all that metal to go threw the motor, gotta be disappointing not to mention the cost. I think the only way to go is roller lifters, I just would not chance it with comp cams. I do run a comp cam, extreme energy with flat tappets but it was purchased over 15 years ago and running. Thanks for that video and just trying to get your point of view on that subject.
The operative word is 'Comp'. They have a problem with their lifter suppliers. Not made in the US. People have been running and breaking in FT cams for decades, 70-80 years at least with no problems. Don't be afraid of FT cams. All these people use Comp and then are surprised when they have a problem when there is plenty of info out there. Using Comp your chance of failure goes up by 50%. I wouldn't use anything from them on general principle if they produce this kind of trash and refuse to correct it.
Like u said if it's there suppliers for flat tappet, why don't they correct this issue, because they are the one who is getting the bad name. Because as it stands I would not spend money on there product.
@@markszczepaniak5888 I've 'heard' that they get their lifters from Federal Mogul/Sealed Power which in turn makes them in Mexico. The only US based flat tappet lifter Mfr is Johnson Lifters in Taylor, Mi. You could just buy a bare cam and your own lifters but I don't think they would warranty it in that case. I think they don't care about the quality because it's cheap for them to send out another cam. But what about all the trash in your engine? There's a long story about why Johnson won't sell lifters to Comp (and Comp doesn't buy them). Some more, 'reputable' companies like Crower, Lunati, Howards, the smaller grinders, have better quality. You can ask them where they get them from. Not positive but I think Comp has standardized to the HT-2011 small block lifter for everything (Chrysler SB/BB).
Good thing ! Thx for the part #s , shooting for a similar set up for my 69 valiant , pretty sure it would be around 320+hp and 380+ torque ( easy 13s with your duster)
I enjoy the fact that you like to experiment! It's obvious that you have fun with your projects. I can't wait to see how this turns out. I'm looking to see what combination makes the most mpg with a daily driver 318. Good luck!
Since you aren't using headers, are you using the stock LA manifolds or the magnum style? You probably already know that the magnum exhaust manifolds are comparable to the "block hugger" shorty headers, (not quite the same, but a big improvement over the LA manifolds.) 👍
Great question! We'll be sticking with the LA 360 manifolds. I don't care for the bulk and weight of the magnums in a Duster, even though they do flow a little better. Thanks for watching!
@@318willrun Me too! Started out to do a cheap home rering. Ended up with a .030 over bore, decking, line hone, bigger valves and a bunch of other expensive crap. 😂
That cam in a 318 is giving away torque with the 114 lobe separation angle and extra exhaust duration. Unless you have a cork for an exhaust system, the Magnum heads are quite good on the exhaust side, they don't need the extra exhaust duration for a typical street engine. A Magnum headed 318 shouldn't need more than a 110 to 112 degree lobe separation angle for a naturally aspirated engine. I understand you already had it on hand. But you can do much better.
The cam I put in my 1982 dodge D150 318 with 30 over pistions is Erson E420121 TQ20H Dur @ .050 : 214/214 Gross lift : .449/.449 Lobe Sep : 112 rpm range : 1800 - 4800 it does alright for a daily driver . wish it had some lope to it
That Sig Erson grind is a great torque cam. I think the advertised dur is something like 292. Pretty high. Long opening and closing ramps. The TQ20 was recommended in a Car Craft 440 build in the '80's. Another nice mild Erson cam is the M/P2. It's a near copy of the Magnum cam. It has the TQ20 intake lobe and the TQ30 exhaust lobe. It's a BB grind but you could get it ground on a SB core. (214/226 @ .050)
Is a magnum engine like an LA engine were you just put the rockers on and tighten them down or do you have to rotate the motor and go through the firing order and tighten them ?
Very fair question. Our reasoning is we have the 318, maximum performance isn't the goal, and mpg are a target as well. So we believe we can obtain the goals (or close to it) with the 318 we own.

Is a magnum engine like an LA engine were you just put the rockers on and tighten them down or do you have to rotate the motor and go through the firing order and tighten them ?
no rocker shaft, but just tighten (torqued) down.
@@318willrun so I don’t have to rotate the engine and go through the firing order ? Just torque down to 21 ft/lb
@@brianwil89 Just tighten them down like a LA. They are hydraulic lifter, even though they are rollers.
Were you ever able to resolve whether the oil pump drive gear needs to be replaced to use an aftermarket cam in an already roller Magnum?
Thanks for the question. If it's not billet, which this cam isn't, I'll use the factory oil pump drive gear.
Do you ever get vapor lock running a mechanical fuel pump and a carb?
Thanks for the great question. The answer is no, we do not deal with vapor lock on any of our vehicles.
I seen a 318 with 340x heads with little better than stock cam with a ton of street races in the 1/4 mile for years
That is a proven combination! Thanks for watching!
Updates?
Yes, my last 4 videos. We're giving the low dollar 318 a chance to run with a few more things in it's favor before pulling it.
