Search results for query: 318 cams

Searching for information on what would make the best interchange for these two blocks. Prefer to keep the Blue 72 and sell a bare black 86 block and heads. Would like to get adjustable rockers. Wonder if cams can swap/interchange over. Will be mated with a 72 904, 8.75 or ¾ 3.23 489 Thanks in...

Plan on getting some late 60's closed chamber 318 heads, Edelbrock rpm intake, 3.23 or 3.55's 2000 stall So I would need a CR higher than 9.1?

I bet if the factory made a performance version of the 318 during the muscle car era we wouldn't be having these discussions. For some reason people have a problem not seeing an engine as a performance engine if there was not a factory one.

318 wasn't "made" to turn rpms because it didn't get the "good parts" like a 340. I've seen 318's turn 7200 rpms for years with stock bottom end. 340's havent' been made for over 50 years, folks are working with what they have or what they can get. It's ridiculous that we can't get past that...

Factory cams are so ridiculously small, you can make a decent upgrade and add good power from the very bottom and gain a few hundred usable RPM up top. cam specs from my 97 5.9 magnum were 250/264 duration w/ 398/401 lift - similar to early LA 318 cams.

What is the biggest cam you can put in a LA 318? I saw something about you can’t put high lift cams in them without grinding down the valve stem guides. Also, what mods other than springs will need to be done?

Think the point is there a way to build a 318 to similar specs as the LS 5.3l and get similar hp and torque, Mainly with similar 217 or 221 cams they used with the 5.3l to get 500 + hp.

Got it. My take was simply to make 500 horse. Frankly, I could give two pops about anything Chevy.

He done at least 3 different 400 hp 318 builds basically 225-245 cams, 9.7-10.5:1 cr, airgap headers, one with magnum heads one with ported 302 heads with 2.02 and one with older EQ then ported them out for 425 hp and and one just added xe262h cam and 4bbl and headers on stock low cr 318 for 282 hp.

I think I am going to go with Oregon cams, we discussed a few different options including re-grinding my vintage 318 cam that is good shape and made of better material. I like the idea of something not mass produced from who knows where.

They're balancing a ton of factors. Drivability, emissions, fuel consumption, 300k miles durability expectations, on and on. These are actual inputs to design.

New 340 blocks and crate engines are available aftermarket. Don't know of they're worth it but....

I don't have a car at this time. I'm researching ways to improve both the torque and throttle response of a 318. I've always liked learning about ways to improve a engines performance. I've read that short duration cams are one way, but what about cylinder heads, what runner size, valve sizes to...

Just curious, what exactly were they doing? I'm interested in your guy's experience and thoughts on this. I got one of their cams recently for a relatively mild 318 build, and in reading up on it, it was very strongly recommended on their site to use only their springs and lifters.

Here we go again, another 318 cam thread and the guys that know a lot are giving their opinions. All good until their ego's get in the way and the thread takes a turn. To the op, read through the dozens of threads already written on the subject and compile your information. Contact some cam...

If rebuilding you can make measurements to find out and make any necessary mods to fit whatever cam you want. What you should be finding out what cams are gonna suit your build and if they require you to do mods to run them piston to valve and or retainer clearance etc.. Then you could decide...

I have 3 318's, 2 from -89 roller cams in cars & 1 solid from -77 sitting & while I was cleaning the roller lifters in one a guy said roller cam engines are Magnum engines... That pussled me as I never though so, what's the correct answer?

The specs on the cam indicate improving low end torque and overall performance, win win for a low compression 318. I now several guys using the Whiplash, one with a 360 and another with a 400, both said the cam made the low compression engines into a different beast.

Almost felt like a personal attack.. my 318 has P295/65-15s :)

True. My 273 Valiant was a nice highway car with 2.76 with a 26'' tire. But getting to 65 MPH seemed to take forever.Avatar photo. The 318 Belvedere I have now also has 2.76 with a 29'' tire has more grunt down lower. Both engines were stock bottom end and stock heads. Edelbrock Performer...

i like their products, but sometimes their customer service puts me off to the point of if i'm able to find it elsewhere i'll go that route. that being said, i like the fact that they offer a supporting cast for the star of the show and it is specifically designed to work together rather than...

factory stock, low-compression LA360-2V short block, with your 318/273 top end, your 904 trans(rebuilt), your convertor(rebalanced) any rear gears with a limited slip, and 318/273 cam With the closed chamber heads, you compression ratio will skim 9/1. The extra cubes will pump up the bottom-end...

hang on... a 318 that ran as good as a 360? This can't be soo..... i am told they are boat anchors :)

Oh, the sound is the mufflers job. The camshaft will produce the rhythm.

Hey everyone i am new here I recently bought a 71 plymouth duster roller no engine or trans I plan on building a mild 318 la that is choppy and has good torque and pep for the street and maybe some strip along with a 46rh trans and 3.23 or 3.55 gears Plan on adding Long tube headers Edelbrock...

I guess that depends on your definition of "smog motor". They had both with and without C.A.P. which is an early stab at smog control. Granted, the engines are built the same, but, are tuned slightly different. The carbs are jetted and adjusted slightly different too.

had bullet cams Bullet Cams Master List regrind an LA 318 cam for me, LA roller shortblock with original lifters, magnum heads, I think Hughes 1110 springs, and RPM air gap. 600CFM edelbrock AFB, hedman headers. intake lobe was their HR259/316, I think the exhaust was HR265/320 on the factory...

Hi team lets me start with thanking all of you for the patience and the knowledge you provide. great stuff. so i had a couple other posts where i mentioned the 74 Duster 318/904 car i got and the different possible routes that i considered to go. i checked on the OEM engine and its a runner...

honestly, if you're going to build a stroked 318, I'd start with an '85-91 block. they have factory roller cams, 302 heads. the roller cam is the biggie. you can get it reground, or get a roller cam and reuse the stock roller lifters at a much lower cost than the retrofit roller lifters...
