Yes, that's what I said. The 318 roller was slightly hotter than the 360 roller, and translates into a mild upgrade when installed in a Magnum.

I'll do that. I don't mean to disturb things, it's that I like to read and research things out and sometimes I don't ask questions the correct way

You asked pretty open ended question, no mention of 318 just 108 vs 112. And for what you want do you need none of this. You trying to over science a very mild combo. When you get a car pick a half dozen of mildest cams and ask which one peeps would go with.

The 350 is making about 30 hp more at 3,000 rpm then the 318 pretty good gain, but the 350 also has better flowing heads.

Do you mean a "stock" 318 ? Or a 318 that has been set up for a large cam?

A friend of mine built a 318 with the TRW 340 repo cam. I don't know if it was the 68 manual spec, but it ran like a scalded dog. You never would guess it was 22 ci down with a set of 3.91's and a stick.

IDK anything about turbos, and IDK your answer, except that 25 years ago, I was on the same road that you are now on. I remember back in the day, a 9/1 318 was advertised at 230 hp/crank, which translates to around 195 rear wheel. And I seem to remember that 8 psi is likely to double your...

Why use 62* a comp cam xe275h is a 63* there's a lot more reasonable cams then that for a 318. Like xe250h, 51* or xe256h 54* are a more reasonable choices even the xe262h 57*, xe268h 60* are less then your eg.. I imagine you could fine similar cams to xe250h or xe256h on 108-107 for even...

Most people aren't gonna port their heads and even if they did no guarantee their gonna get great results. So your basically talking stock or pay someone else to do it. If looking for decent power 300-425 hp stock 273/318 heads aren't the way to go. Especially with mild cams and CR. I'm sure if...

Any 318 that runs will produce MORE torque than the 318 you do not have. :poke:sorry Dan, I had to ..... :D

Thinking a 318 needs a stroker kit to make 350-400 hp is a mistake. And in a race to 400 hp, at todays prices, starting from scratch, the 318 is still the better buy on the pocket book than a 340. And 318's have roller cams from about '85 to 2002. And if looking for 300 hp for a Dairy Queen...

I’m sticking in a cam in a 318 this weekend and I’m cleaning parts in preparation. Needed a set of lifters and decided on Howard’s 91711. I disassemble and clean any lifter that goes in an engine I put together, and I just finished these. Gotta say, other than some light machine oil, these were...

So quick question. There's a few "brand x" 5.3 builds up on YouTube by our beloved Richard holdener. In his usual style he gets a junkyard engine and tops it with heads cam and intake to get to a desired power level. In one of them he's getting 500+ with a pretty mild BTR hydraulic roller...

He did 3 that I know of one with magnum heads one with ported 302 heads and one with older eq's then he ported the eq's for 425 hp. Think the cams were comp 280, xe268h, xe285h on 10 ish to 1.

I may add, margin of error for flow testing should be taken into account. I flowed 2 ports on each head and took the average. Most stock 318 heads crap out and most performance cams are less than .480 lift anyway. For future reference and kids that find this later. It's not worth buying the...

No doubt! In addition…. Cam size dependent, little to no loss of low end torque worth mentioning. Address the cylinder heads for better power no matter the cam size. He never mentions header size IIRC. He would get called out instantly by you and I right quick. I have 2 sets of those. IMO, a...

Cores to build are plentiful. That is a plus. Most parts that would fit on a 340 or 360 will bolt onto the 318. As Nick's Garage showed, a stroked 318 putting out over 400HP and pound feet of torque is no slouch. Like the Chev 305 and Ford 302, the 318 emissions engines got cams with reduced...

I have done a couple magnum swaps. Probably cheaper than most. I buy a truck. Rusted rotted junk for 300 to 800 bucks. Pull the engine, flex plate, starter, and anything else worth saving. Sell any parts that you can sell of the truck quick and easy. Scrap the rest for most of your money...

A running mildly hop up magnum is the best bang for the dollar, people get too hung up on the cracked head problem. It only matters if rebuilding and generally aftermarket heads are the way to go anyways in that case.

I was thinking similar, but even still though the popular LS 706 is topping 230 cfm @ .700 getting 2 -2.4 hp per cfm with what most would consider fairly mild cams for the output. Magnums are know to respond well to cams and don't flow that much worse, seems to make like a 100 hp less with...

How about a test and tune this summer? No aftermarket cylinder heads, no custom ground cams, bowl clean up no gasket matching, 3 angle valve job allowed, back cutting the valve's allowed. Factory ignition. No headers. 318 engine

Kinda smaller than a stock 340 one. We always used them like a performer and worked from idle to what cam did. But only ran stock size 340 cams with them. Good intake on 318, 340 and very mild, and A/C

Boost? Where did he say something about boost?

The 1798 and required support hardware would be good for a stock 318 with about 7 pounds of boost and a factory high stall converter. Otherwise, it would need a pile of compresson, good heads, gearing, and a high end torque converter. If you must improve the 318 with a camshaft with minimal...

Ive never sprayed this motor i sprayed a 68 dart 270 318 340 heads hemi cam torker door stop 650 dp 3.23s Also sprayed a70 duster 340 243@50 gk cam same torker door stop same 650 dp carb same unilte 3.23s This motor came out of 68 gts i raced@80k miles ran 14.3@97 plus all stock 3.23s ended up...

Ima thinking you(A56) know this; but for newbes reading this; Without headers, the Overlap cycle is sacrificed. All cams have overlap, even the factory 318 cam. Some say that headers put an easy 35 horsepower on an early 340, and that 340 cam sported only 44* of overlap. IDK if that is true...

I have a few sets of SB 360/340/318 heads that are completely machined and ready to bolt on and go... They are 360 castings years range typically from 73 - 77, they will perform better than any stock 340 X or J head... Ported with hardened exhaust seats, new 2.02" intake valves, new 1.60"...

Wait until you start looking at 318 cams. :BangHead: :rofl: :rofl: I'll look through my bookmarks and see if I can find a thread or two. I know I saved some about manifolds.

Sounds very healthy , with all of the 318 threads here, I'm sure you will be inundated with...I wish you would have dyno tested or how much HP does it make? Good job nonetheless. J.Rob

I’ve had this thought for a while. I think it’s the ports. I bet if you analyzed one of those ports you’d find it has good speed and port energy. Plus the combustion chamber is 40 years advanced vs our old iron heads. And they respond to cam swaps well because the factory cams are tiny! On non...
