This is the 1970 318 in my Dart. As a kid, I set it up with a competition cams 268H, single plane intake and Holley 750, and 360 J heads. Not the optimal combination for power, but it was still fun. Hopefully I get it running again!

Aren't you using a Isky E4 ? Short on lift but not too different on other specs Solid Valve Lift Int/Ext. 0.425 Valve Lash Hot Int/Ext. 0.015 ADV Duration Int/Ext. 260 0.050 Duration Int/Ext. 216 Lobe Center 108

Very cool!

That's been done numerous times over the years

Yes and no. It’s a lot of boost. Double the sea level psi into the engine and you now have twice the engine size. 5.3 turns into a 10.6. Now how hard is it to make power with an engine size that large? The OEM cylinder head for the early engines even ported is behind a modern LS. Sub it out for...

The LS heads are far better than most heads for a SBM.

My guess it's mainly down to the heads, I'm think probably due to velocity and maybe the exhaust port is playing a role. I've been trying to figure it out also, lately.

Some of those LS heads are just that good. They really are.

Hi AJ, I think I've seen you write that you've ran the 318 cam in a 340 engine. What is the theory behind that? Thanks in advance.

I don’t bother recommending cams. For a long time now. It’s not the pissing matches that idk me but it’s ether splitting of hairs on similar cam specs or its wildly different and sometimes absurd cam recommendations. Now, if asked, directly or via a thread, it’s just a general recommendation...

A stoker kit for a 318 is going to run you about $2K. If it was me, I'd keep the stock stroke and use the KB167's, put 1.88/1.60 valves in the heads and have them pocket ported/bowl blended and a Comp Cams 268H or something similar from Howard's Cams. If you know for sure you want a stroker, a...

Because some topics (sarcasm!!!) turn into racing threads even though you want a very small upgrade on your cam. Congratulations Dan! You now have a Pro Stock cam for your stock 318!!!! Enjoy!!!

The extra exhaust duration helps get more exhaust gases out and will add a few more rpm to a single patterned camshaft. Headers or not. I running this one in my 5.9 with the trick Hughes springs and retainers. (727/2500 stall, 3.55 gears.) Mellings makes OEM repops. Patents expire after...

But it sounds like the op doesn't care about "more power' or "most gains" or "maximum" anything. He just wants a cam that works with his combo that has a "noticeable idle." Here's a 318 with a Whiplash cam. (I don't know which one) Sounds nice at idle. It probably smoothes right out at about...

I get your point and not totally disagreeing or saying the OP should go with a big cam. Yes bigger cams extend the upper rpm powerband and make most gains on top but they also generally add decently in the 3000-5000 rpm range also making a lot more power then stock and decently over a smaller...

Okay I crashed the dart into a telephone pole after I lost all braking. So I took the entire car apart and I have the engine pulled looking to make more power. I recently bought a COMP CAMS KIT I’ll post a picture below of the specs. Im just wondering what 390 stroker kit is best for my 318 with...

Yeah no worries it is definitely either a 1990 or 91 block that I pulled out of a 1981 D300! I have the roller lifters and spider hold down that came with it. When I first discovered the cracked heads were magnum heads I initially thought I had a complete magnum motor. A few years later I...

Sounds like ya got it whipped. Excellent. I never had to deal with that kind of heat you have. I have to agree that the aluminum does run cooler. This was in lower New York. What kind of fan are you running?

9.5:1 on the Aluminum head cars. Had 8:5:1 on my stock steel head 318. All run plates to allow 18 degrees idle and 30 all in. Cams are all low duration hitting around 7.5 dynamic and 185 PSI cranking (the cast head build was lower) My car with the stock cast heads and low compression pinged...

What are the current specs on your cam? Go to answer is: get a custom cam. Racer Brown and others. You may be able to regrind the one you have since you are going smaller. I used to get 25 mpg+ steady cruising with a 340 cam and a TQ in a 273. Using a vacuum gage helps to teach you how to...

There have been novels written here about 318 cams. Use the search function and study. I see 17 pages of threads. Search results for query: 318 cam

12 second bracket, not a good choice with your running gear. What car? That or one step larger at max. The manual can handle the next size up depending on what it is & the compression ratio of the engine now.

Look at Hughes Whiplash cams

...maybe 318 manifolds... So to recap, I'm building a fun 71 Demon. Dropping in a nice warm magnum 318, with a 4bbl and nice '340' cam, and an A-833od 4-speed, and 3.23 gears - just a nice clean-running hot street machine that cruises perfectly on the highway and idles with a bit of lope -...

That is NOT "installing" a performance cam. Performance cams (or really, even stock ones) need to be checked. Google up "degreeing a cam" There are lots of websites and videos, some by the am manufacturers on doing so. I helped a guy REALLY wake up a 318 that was nearly 12* off...

Depends on what year your Stock 318 is? '68 & '69 are the stock 230 hp 9.2:1 compression engines. Same with the '89 - '91 318 roller engines 9.2:1 cr and these come from the factory with the 302 closed chamber heads. Both of these engine years perform well and run very nice with the stock...

I was at the mercy of the cam supplier. As I said, not a cam guy. Got tired of reading comments on cams so did the best I could. Still at a loss and don't know what to do. If I were to purchase another cam would be the same story. Thanks for your comments.

Thought I explained the cam was degreed. Why am I getting blasted on doing so?

I’d look at something similar to the Eddy Performer RPM or just plain Performer cam kits. Both are relatively mild cams designed for stock heads. At least in small block fashion.

First, you need a car. You should tailor some mods with a car in mind, like 66 down or 67 up. Any 318 will make a really nice street car. What do you want. All around, drive anywhere, pump gas, decent mpg? Think a 340 Duster? NO special parts needed. 318 short block, 360 heads, cast 340...
