360 heads only serve to make an already low compression ratio even worse.

I don't think the 318 heads are necessarily bad, it seems they flow better than a lot of Fords 302 heads but 5.9l/360 heads are just gonna give you a big jump in power, other than throwing a cam 4bbl exhaust on a running 318, I don't know why people insist on running 318 heads when looking for...

Actually in the beginning I said a stock 340 cam then just to kick them in the pants I said the 318 cam. I owned a couple of 1979 Chrysler 300's. They came with the 340 cams dual exhaust ect. They sounded great, had a little power but overall they were dogs. One of them I rebuilt and the final...

318 LA block (budget friendly), 920 closed chamber heads (from a 273) RV type cam, 600 cfm carb, w/Edelbrock Performer intake, cheap long tube headers. 65'

Less with a overbore.

What do you think you could get that 318 short block for ? If pretty cheap, could do Speedmaster top end with something like a xe268h cam specs on that 328 short block might be a little shy of 400 hp but still give you decent performance especially with a stall. If not could do a zero deck 360...

It has the 67' 273 valve covers, so someone tried to make it look like a 273. First thing I would do before driving it is, change the thermostat housing. Those chrome ones always leak.

Let the machinist decide if it needs it or not. The conditions of the cylinder will be determined then. The machinist will probably opt for a .030. I like the cam. Increasing duration moves the power band upwards. If you like how it performs now, keep the cam. No. You can if you want but it’s...

When you hit the reply or quote button, type outside the quote tags. They will have a bracket “[ ]” I have run the LD modified as per the book and have done so without issues on a low compression 318, mild Hyd. cam,, 4spd manual & 4.10’s. The carb was the 440 TQ. It has the same size primaries...

If you have Commando pistons already and they match up bore wise to 273 block you have access to, it's a no brainer. Rering, rebearing and cam upgrade if you so choose. I wanted to add more hp and looked at building a 318. From my memory 318 pistons to achieve decent compression werent cheap.

...melling cam is spd25. I think the 340 cam is spd22. I've used a couple of those 25s before in 318s, noticeable win power, idles like stock 318 cam. Exactly the same thing as the comp 252 minus 0.015" lift. Duration and overlap are dead nuts the same as the comp at a cheaper price. Good for a...

Somewhere about 86 didn't the 318 get a roller cam?

if you're starting from square one, the most economical way to make more power is with more cubes. a 360 is cheap, abundant and has an absolute massive amount of less expensive go fast parts. THAT IS WHY EVERYBODY SAYS BUILD A 360 it takes more compression, more cam, more RPM and better heads...

Hey all, this might be a question with a really elementary answer, but I just want to make sure. I have a 1974 la318 with a set of 587 360 heads. I’m not sure the build on the engine, I believe .030 over and possibly a very mild cam. I have a stuck intake valve on cylinder 3. If it’s not just a...

Other than displacement with the 5.9l which would help with lack of gear. It's mainly the heads cause there capable to reach 400 hp. Nothing stopping you using the 318 bottom end (but I would run less cam so less power but up to you) and could grab a set from a scrap yard and hope there just...

318 had 300k on it and was getting tired! And yes, I had a decent 6 laying around, and had just acquired an AT that I could rebuild and use. Selling the V8 and AT out of the car supplied enough $$ to cover related switch costs, plus some extra for whatever. Basically I just like the simplicity...

Here some info on mild 273/318/360 273 https://www.motortrend.com/how-to/testing-mopar-273-power-pak-dyno/ 318 https://www.motortrend.com/how-to/mopp-0312-318-long-block-bolt-ons/#:~:text=Our 318 now produced 282 hp at 5,000,hp by an intake, carb, and cam change 360...

Right! Another way to get there (390 cubes) is the 4.00 arm in a bored out 318. Add a good head and a cam! Hummmm, a 360 crank @ 3.58 into a 340 block bored to 4.100 for a 378.12 or a 6.2. Add a good head & cam! Right! 3.58 (360 crank) into a bored out 318. Might as well go .030 over...

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.

that's just greedy :poke: :rofl:

What the heck? How many did they make like that?

Exactly! They do not give advertised numbers anywhere on there site. Never did. No one knows the advertised numbers unless they figured it out themselves on there engine or had it “Cam Doctored.” Freakin funny ****. He still finds a place to cry about and bash a 318. The only place it’s...

Where are Where are your 340's?

I know you were just messing around :) And i have 4.57's.. it should go ok.. it's a temp motor to get the car mobile is all for now

K. Thanks. I was just wondering. I know that comp cams and lunati show the advertised duration, it's no big deal I was just curious

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

ask and ye shall receive. people out here acting like mid 12's from a 318 is witchcraft or you gotta make a deal with the devil. converter and gears will easily push a 318 into the 12's i have a 69 barracuda, full curb weight. 318/727 stock stall w/ 3.23's the motor is an honest 9.5:1 with a...

I can't answer your questions, but that combo, if my numbers are right, is gonna come in around 9.7 Scr which is not nearly enough for that cam, even down at sealevel. Installed at 104*, the Wallace Calculator predicts just 145 psi, with a Dynamic compression ratio of just 7.3.. Under those...

We are trying to get 1959 Plymouth Fury mobile for the first time in 40 years. We picked up a low mileage 1972 318 from an RV. We disassembled it for inspection, pistons were clean, can still see cross hatching in the cylinders and all the bearings looked good. I understand these industrial...

I’d call that an idle to 6,000 intake. But of course, like said above, a larger camshaft and ported head and etc….. you get the idea… I really don’t see a problem to 6500. I do wonder what the old catalogs listed it as. Hummmm I had one on a 318, small cam, 216@050. I’d run it to 5500. That’s...
