Almost all poly 318's and '60-7? slants have solid cams from the factory too.

I used the roller version of that in a 360 mag with 11.1 compression measured. It was an absolute torque monster in a 78 power wagon, pulling an open car trailer, the first time my cousin rode with me, I opened it up. He said holy ****, this thing revs like a dirt stock car. Idle until the...

Ok, been looking for a 318/5.2L .432 roller cam to put into a 5.9 ever since I read about them to get a little extra something out of an otherwise stock setup. As I understood it, these were PRE magnum cams. So, I pulled one from a 85 5th ave and it measures 0.390 (.260 x 1.5).... ?? Are the...

There's tons of 318 cam threads here. There's info on a few cams that are specifically ground for a 318 with a 4 barrel and dual exhaust. I just looked through my bookmarks and couldn't find the thread. Sorry.

The alloy heads when combined with a tight quench, will support very high cylinder pressure on pumpgas . Good luck getting there with flat-tops and a 340 cam. It will never happen. See Note-1 If you ignore the pressure possibility, the guy in the next lane with an identical set up but pushing...

That's Melling. Not Chrysler. Specs could very well be different and they usually were in the aftermarket.

Thats a decent cam. But for stock long block 318 I would chose a cam with a faster ramp. The difference between the duration @50 and the advertised duration. The larger that number the lower the cylinder pressure will be. With a stock 318 your compression is already low. Any of the new cams like...

In my book, the windage trays, distributors, and camshafts are not the "same". Will they bolt on? Sure, but, they're not identical. The windage tray needs to be tweaked a bit to keep it from rubbing the crank if you put a 318/340 tray on a 360. Cams and distributor specs are different.

This may not help the OP, but the SUM-6900 cam and lifters is what I ended up using in my 74 318. Bone-stock low-compression bottom end with the cam, duals, and an 1406 Edelbrock on a Performer intake. I currently still have 2.76 gears and a stock convertor. I noticed no loss of low-end and...

What exactly do you mean by "how big a cam?" You can put a long duration cam in, but you will loose bottom end torque and gain high RPM power. For that the rest needs to be up to the forces the RPM generate. Rod bolts and valve springs come to mind just off the top. A high lift lobe also...

. The EH1 was not an E58. It was a modified E58. The EH1 only came out in the LRE. It had a bigger carb than the E58 engines. Where is it written that the 79 LRE used a differant cam? What about the 1980 LRE's that went to Canada?

Gearing and your torque converter are your holdup. You already know this. Address that second! Have you addressed your suspension, tires and brakes first? If you can't control or stop your car, you better not go fast. Hydraulic rollers will never rev as high as solid flat tappet. What heads do...

I have a 1987 318. The heads I had rebuilt are from an earlier 318. I'm curious if I need to use the stock valvesprings from the roller cam engines. My machinist thought that the factory roller cams are really tame and that the flat tappet spec springs would be fine. What do you all think ?

Need to watch the David Vizard Powertec 10 Youtube video discussing cam selection and how cam companies get it wrong. His method is the LSA is the input based on cylinder volume divided by intake valve diameter multiplied by 0.91. This is subtracted from 128 for SBC and 127 for SBF. Most...

That is why I specified LA engines. Big blocks and Hemi's also came with solid lifters.

Here below is an example of someone thinking his way through a combination, not saying anything directly applies to your build, Not meant as a recipe to follow but a piece of someone redesign a engine driveline combo, just an eg.. to give you kind of an idea what I meant by come up with a gameplan.

Because you’re talking about a stock stroke 318, I would go with this one if it were available. Hydraulic Roller Rattler Camshaft; 1964 - 2003 Chrysler 273, 340, 360 1800 to 5500 Howards Cams 718005-09 | Howards Cams But if you can’t find one, Oregon hydraulic roller grind 1386. 224/[email protected]...

For a streeter, those two boxes are so close, it's hardly worth thinking about. 2.66-1.92-1.40-1.00/ splits of .722-.729-.714 versus 2.47-1.77-1.34-1.00/ splits of .717-.757-.746. This is because, Second gear will get you into speeding territory after about 5.5 seconds, and before you hit...

I agree the ramps are over well before .050 but it would probably would also be useful to check the duration @ .050 to see if the cam would be effective for his application. It appears that he does not know much about it at all.

So I recently bought a bone stock '73 318 2 barrel. Since it is going to need to beat up on some stock mustangs from my high school, I am going to do a cam swap and put on a '71 340 4 barrel intake I got with the engine. My question is; since I am only changing the cam and intake, what cam...

Can the cams be interchanged?

I agree, those cams are too big for a stock 318 2 bbl... If anything install a stock 340 automatic cam... 268-276 .429/.444 lift.... Here's a few good choices: DODGE COMP Cams 20-222-3 COMP Cams Xtreme Energy Camshafts | Summit Racing DODGE COMP Cams 20-309-4 COMP Cams Magnum Muscle...

Yup. You're right. I compared pictures of both and the lifter bores on the LA are a good bit shorter. It's funny though, Comp Cams offers a kit for the Cleveland engines that utilizes the Ford small block spider and dog bones. The lifter bores in those engines are the same as the windsor roller...

Yeah, I was really posting for those who don't know about all the poly motors. Lotta confusion about fifties Chrysler Corp motors. When I replaced my timing chain, I found out that 56 Plymouth poly motors had a one year only cast iron timing cover, with the water pump sitting higher than later...

I am having my 318 rebuilt with new rings, bearings, rods, pistons etc.... The engine will have a roller cam installed and I am wondering if a high zinc oil is still required? The engine will be torque plate honed. From what I have read it should be run in on dino oil but can't see where zinc...

To be fair, I'd either run all 3 stock or all 3 fully worked over. Unfortunately, while it would be interesting, the time it would consume, and financing will not allow me to do this kind of test. I'm overloaded with projects...lol

My theory, assuming its a well used and aged 318 and you probably have to replace or repair these items anyways is as follows: 1. exhaust. 340 hp manifolds or more affordable 360 magnum manifolds, 2.5" dual exhaust, good sounding muffler and depending on your budget H, X pipe . As a near stock...

I used to do it all the time. But, I also added milled 360 heads, TQ, intake, dual exhaust, changed the curve in the distributor, added a windage tray, high pressure oil pump spring, and upped the pressure in the trans. For some reason they'd run like a 72-73 340... There are better cams...

A big port intake on a small port head is a mismatch in my book. The first factory LA 318 4bbl's started in 1978. By then you had lots of smog equipment, different castings, but still, ports that matched. Mild cams, lean burn, thermoquads, mild compression ratios and cams, restrictive exhausts...

Dale, I did not say 302 but did say 5.0. Maybe I should of added 90's Mustangs that had 5.0 badges, dual exhausts, manual transmissions and romping cams. Would also add, I never pushed a run on the streets, so if someone wanted to "HOT DOG" it and it was a safe street I would take them on. Don't...
