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...

. 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?

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...

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

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...

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...

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...

I would measure what you have, I bet that 318 is closer to 7.5 on compression.

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

Think the Hughes cams are ground by Howard’s which is Competition Products. Chrysler SB 273-360 '65-'95, 318 '67-'95 Cams Downloads | Howards Cams Here is the lobe list. The cost of a custom ground vs a off the shelf is 20 bucks more. Only thing may be delivery time. There is lobes they grind...

Where to start... It was a general statement why I would pick a 383 over a 360 having daily driven Factory A-Bodies with a 383 and a 340. The "seems to be a long-standing, common knowledge in a Mopar world" is actually a long standing common misconception. As for the extra weight it really...

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...

The cams are different. The 318 roller will be more lift and mag is more lift @.432+ than the stock 5.9 stock cams that were only .410-416 lift based on a 1.6 The rt magnum cams were more lift than the reg stock mag 5.9 stock cams @.434+or something like that.. but with a diff duration than the...

That would be a good test. There sure seems to be a lot if negativity about a 318 not being able to handle a 340 cam. No bottom end and at least a converter to make it work. Is it really that big of a pooch from say idle to 3500 rpm or is it just nobody knows how to tune a 2 barrel and...

Just looked it up and confirmed 318 la roller cams are 240/.391. Factory la 360s are 252/.410.

Yes from my understanding the larger 318 cams came out of the 5.2 magnum engines not roller 318s

Oh LAWD! The timing covers on all the early polys and hemis were just dreadfully HEAVY. Especially the Chrysler Firepower truck motors. I just BET by swapping over to the Hot Heads cast aluminum timing cover and the Big Chevy aluminum water pump that I got rid of 75 pounds off the front of that...
