I see you are from the UK so your selection may be a bit limited. There's a lot of talk about issues with Comp cams and lifters.

Here is the perfect up and running stock 1970 318 with the factory 2 bbl carb and single plane intake. Great engine for stock 318 power peformace testing, to see what power an untouched stock 318 will make. As a baseline to the other engines people are building as they are adding ported heads...

This is an interesting question of 360 vs 383. With the intro of affordable speed parts that began about 25 years ago for mopars its really a wash. Today and relatively speaking the affordable stroker kits, aluminum heads and assortment of Hyd and solid roller cams is the determining factor...

Unfortunately for you, 318 and cams, opinions vary on here, aka highly debated.

Shooooooooot, I always go one or two bigger lol.

Looking at cam specs only serves to make my head spin..... All they do is confuse the hell out of me. I put what was supposed to be an erson "340 spec" cam in a 318 in a Cordoba back in the 80s, and it made a lotta noise but was the biggest disappointment/ dawg I ever had. Since, usually once I...

How much more power did you gain with light rods and floating pins?

I had a 66 Barracuda, 318 w/302 heads, KB-167's, Comp Cams 268H hft, Weiand Action Plus intake, Edelbrock 1406 carb and headers. Heads had bigger valves (1.88/1.60) installed and a little bowl blending. Never had it on a dyno but it ran really nice, "fast according to my butt-meter".

My main goal is to have a car that has good throttle response and low to midrange torque, have the ability to get out of its own way and to have some stop light to stop light fun once in awhile. Idle quality is not a issue but to have a good torque cam means a smooth Idle, I wouldn't mind a...

One of the things I question myself is .... when I did the cam swap only, it was back in the day. Cams are "smarter" so to speak? Maybe now, the cam would produce more of a result ?? But heads have come along way also.

If leaving the 302 heads stock, I wouldn't bother, time and money for no real gain. You a least want to gain head flow if doing a swap, A magnum head or milled 360 swap keep/gain cr while giving more flow, if willing do some porting can add 273/318 heads back in the mix but you can also port the...

Depends who you ask :) it looks about right to me, think about milling a bit of the heads and or deck to bump cr closer to 9:1 ?

A stock '69 340 pre- low compression, smaller valves debacle, had according to NHRA 300+ hp. That car new would run low 14s' all day easily without headers. Remember, Ronnie Sox drove one with fender well exit headers, Holley carb, Edelbrock intake, 4 speed, 3:91 SG to 13.3 106 mph with street...

if you're talking straight up easy and cheap-- 5.2 or 5.9 magnum, snap on a 4bbl intake send the cam to oregon and have it reground, thin headgaskets to bring the compression up and roll. if you're even thinking of going roller cam on an LA, start with a roller block. or, again a magnum...

i i have promaxx heads on my 318/390 stroker.....ported them a little...widened pushrod pinch....blended chamber/seat area...unshrouded inlet valve ... has a lunati hyd roller......232/[email protected] lift....port matched airgap...750 mech secondary....11-1 comp....excellent street combo....pulls...

Man, I've tossed Bunches of cams... who would have seen this coming?

Do not burden yourself with all those whose first response is to build a 360. Nothing wrong with 318 engines. Yes it is easier to get 400HP out of a 360, but sometimes you go with what you have or have available. What heads are you thinking about, and valve sizes? Aluminium are lighter and not...

A Manifold thread turns to Cams. I love it. Still have not installed my Isky but I know it will be monster. Was told this should not be annoying with 904 and 3:23s. Will benefit with more stall. The car is just so pleasant to drive as Chrysler intended I am waiting to swap when I can massage...

May as well, just go for a generic brown box Hydraulic flat tappet cam.

Heads are basically the number 1 component for NA hp especially streetable hp, look to the LS 5.3l same basic displacement, smaller bore not overly high stock cr. In dyno trim (headers, tune, no accessories) stock cam makes 350 hp and with a 218 @ fifty cam well into the 400 hp range and most...

Probably so. 73 340's ran pretty good but they were pretty anemic compared to the 68 and newer ones. 73 was the last year for the 340 and everything got a 318 or 360 from there. The 360's were built like the 340's of that era. Heads, cams, manifolds, etc were interchangeable. The 360 would...

i think you've got a lot of the bits and bobs there to make something pretty rock and roll, but it really comes down to budget and pain in the *** factor. as somebody that's always built my own junk on a beer budget, and currently going thru a "dedicated cheapskate" 318 build i can certainly...

I know the Voodoo line is more aggressive, but I was unaware they actually used Mopar lobes.

@Dan the man Here are some theoretical cams, to show you what happens to LSA/etcetera, whilst adjusting the overlap period. this is just an exercise. all are in at split overlap. I set the Ica to 62* for a compression period of 118, which is typical street I set the intake/exhaust split to 4*...

Well, they were when I bought the 60404 that’s in the 340 in my Duster and the 60403 that’s in the 318 for my Dart. The Lunati’s have faster ramps than the purple cams did, higher lift on similar durations. That would be really tough on a narrower lobe.

IMO, again, don’t worry about the cam, use the 340 block, stroke it with an all forged rotating assembly. Can you port your own heads?

KB 167's are a popular option. Near 0 deck height. They are around 10:1 with a .039 gasket.

Stick with cams like 340 cam or 268 Comp Cams. Note. The performer has smaller ports than the 1973 340 TQ intake has. I know you say you have the Performer but you will be running 318 small ports on a larger 340-360 port head. It will ne fine low end mid range but will reduce power on upper...

keep in mind, the cam in the 360 was going to have a stock torque converter and highway gears... started as 2.45's and now 3.23's. Better converter and gears, the engine would come to life with a better cam. It's why I say, if you do not plan to go to the drag way or race the car ever, just...

To the OP… what cams did summit suggest for it? Also, what head gaskets were used in the changeover? If it’s not something close to the factory steel shim head gaskets with the usual stock 68cc or more actual open chamber 318 head volume, a cam larger than a stock 318 hydraulic flat tappet is...
