For sure good thoughts and you are correct! But, for this project in particular, we'll be using the factory intake and exhaust manifolds. Thanks for watching!!
Up into the 13s around home and in the 14s to 15s on highway trips depending on wind, in an 81 W250, 318 4sp 4.10 gears. Probably could've done it with a two barrel but it's just easier to get jets and metering rods for a 625 Carter Competition, exact same carb as an Edelbrock Preformer. Intake is a 68 340. Best mileage it ever got with a two barrel was 11, normally wouldn't hit 10. Motor is a 1974 that still had steel intake gaskets, think I was the first one inside.
Great video! I'll follow along closely. I will be looking to squeeze as much as possible out of the 318 in my Duster. I'll watch what you do then maybe share what I do to mine. Thanks for sharing!
Are you porting for fuel efficiency as well then? 8 kept my 1.78 valve heads when I ported mine. I think you would be surprised how well. Some well thought out/heavily ported 1.78 valve heads will do. Especially with the amount of velocity you can get going through those heads. My 318 is incredibly snappy after porting the heads, and four barrel intake
Nice video....congrats! Here in Brazil is really hard to find information about the 318 mopar! I hope someday I'll buy one of them and use your videos to help me get more hp! Thank you God bless you 🇧🇷🇺🇲
I know you guys ×ont like it. But try going backroads at 55 and getting up to speed like a grandma. You can really increase your furl economy that way on long trips.
For sure driving habits make a huge difference ! We like the backroads because of the scenery, and I won't push it in todays speeds. 65 on the interstates and 55-60 single highways. We had to take off like a grandma no matter if we wanted to or not !!! Ha ! Thanks for watching!
This was great to watch when you decided to pull the dizzy ! Yes!😁.... Have you ever used Hughes engines valve stems seals they are postive seal type I'm using HUG3820. 3\8" x .625 guide they help in keeping oil dilution down in the fuel charge which helps gas mileage they are on my 318 roller cam rockauto also has a version look for a 90 ramcharger to look them up if you choose to try them
Advance your cam 4*. Back cut the intake valves. Remove large advance spring from distributor. I am also experiment with a slant 6 carb. I run a 73 step side . My best is 19mpg. The lockup tranny out of a diplomat is the reason.
Nice one! This is why I like your channel! It’s like you mentioned that you wanted to reuse the stock parts, and get 10 comments about changing them out. It’s gotta be more fun to do the things they say can’t be done! I guess it’s more that people don’t want to try it and see. Thanks for sharing! Don’t forget your NGK plugs 😜
I have an old buddy that's a Ford man and he has a great collection of cars/trucks and he's a good time. Im a Mopar guy and I reckon if he lived on one side of me and you lived on the other Id have some fantastic neighbors.
There's something beautiful about working on an engine from the inside. I miss that view of having the dog House off and having everything right there.
You might be surprised about those stock push rods & their length. While they’re out measure them & just see if any are shorter. Put a straight edge across the valve stems tip even if you have the valves machined. Proper preload on the lifter & correct lift at the rocker makes some cheap reliable power. And better cruising
Thank you! I understand for sure !! In general, this van doesn't see any more than a 1/2 inch of gas.... usually racing is the farthest things from my mind when we are out in it. But on Sept 30, it will do battle with the H.G. van, we'll most likely lose 😁
Life of spark plugs will suffer but you can sidegap & index your plugs and point the open gap to the intake valve. Did this to a 361 big block and noticed an MPG boost and better responsiveness.
@@318willrun No problem at all. I also forgot, you may need to tweak the spark plug gap to be a bit bigger from factory spec, 35 thousands for stock spec, I made the gap bigger by 3 thousands, 38 plug gap is what I have. The above modifications will be more noticable if you have a high voltage coil. I set my distributor point gap to 20. Factory was 30? 32? With the point gap at that setting, you may notice the exhaust note is louder, more booming? Sorry for the long post, I didn't want to leave you hanging without getting the whole picture of the modifications. Initial timing is 20* The 361 I have is fairly low compression so I didn't bother with the total timing, doesn't detonate or anything which is interesting.
Well. That's a good start. A quick valve lapping wouldn't hurt, as well as cleaning and tuning the carb (throw the intake and carb from dragtruck and put on it!). Too bad you didn't have time to put a .260° @ .5" lift cam it it to breath better from mid to top end. Good luck with the tuning!
Heck yeah this is going to help you gain performance and fuel mileage alot. Are you planning to "clean up the ports, bowls, and resurface them 050 to even things up . All of those goodies will definitely help you out with fuel mileage and power because the heads will be so much more efficient and while saving fuel you'll be making more powah which of course you already know because this isn't your first rodeo and you have probably forgotten more than most people will ever know . You forgot more in one day than I've learned in a lifetime 🤪🤣😂 I can't wait to see how it works out for ya 💪🏼😁🚙💨💨💨💨💨
Would a electric fan help? Even with factory manifolds still go double exhaust. Never had luck with the bb2 Carter any tips would be great. My 70 d200 318 auto 4:10 gears. Got 13 mpg. I still want a wide band o2. Great videos.
If you really want MPG, stop messing with the marginal gains you will get in that engine. Simplest most reliable change that will help is a A518/A500 automatic. You need to drop the engine RPM at highway speeds. Another option maybe to go to 2.73 ish geared rear axle, but IDK what you are running now. Finally ditch the carb. for a TBI. Those will move the MPG much further then swapping engine parts.
Why does your black van have an Arizona plate on the front when Arizona only requires rear plates and as far as I know only issues one plate? Is it because they are personal plates?
Hey! if you were to change camshaft, with power and economy in mind on a van like these (hills and cruising and such), do you have any recommendations? Im abouyt to rebuild my 318 on my 83 camper. Any help would be greatly appreciated!
I would probably call a cam company, like hughes, and tell them what you have and what you want. I also would consider advancing the factory cam 4 degrees.
Have you thought about going EFI? I'm not sure if that'll help or not. I think it could be pretty cheap, maybe gain some HPs too? Like the progress so far. I just stumbled across your channel! Neat little project you got going
@@318willrun Ah gotcha! Well I'm excited to see where this heads! I'm not too familiar with working on vehicles. I got the EFI idea from Vicegripegarage, he sometimes does that and stuff. Will getting a 4 barrel carb help too? I'm not really sure, just pitching ideas :D
@@318willrun that is the smartest thing to do, simple and trouble free, i would even stay with the 2 bbl. if the cam remains the same it will be pretty much the same engine
My truck has the aerodynamics of a cigarette machine ..lol definitely not good for fuel efficiency 😁 Great video 318WR 👍
Thanks 👍
Add headers. Always the best return for hp and mileage. Also, how about a old sp2p intake with a 2bbl adapter. Food for thought
