    64 barracuda 273

    Use the 273 with the 318 heads and the "67" 273 4 barrel intake. You need the 318 heads to use the 66 up intake manifold. You can always mill the 318 heads to get the compression you want. Run the Commando exhaust or clone it. Easy to get 265 hp out of a 273 with 2 barrel pistons, a small...

    Horsepower Estimate?

    Pretty spot on, however I'm not sure about stock 318 having 150 untapped. Those heads suuuuuck.

    Cheap 318 performance mods.

    off the cuff, something like a factory 340 converter would be fine so what 22~2500 (that would be for a low end converter). i mean considering a stock 318 converter is like, negative stall (i'm kidding it's probably 1800) i'd think anything 2+ would be an improvement. now if you're talking high...

    How far in the hole 318 pistons

    Does anyone know how far down a 1972 318 pistons are? In a book I have it states in 1972-1981 they are .056 down from the top of the bore but with those calculations in the Diamond racing compression calculator it gives about 8.5 to one compression but our factory manuals state 8.2 compression...

    Not sure what to do

    as above run what you have and build as you can afford a better motor. if you can't find a reasonably priced 360 in your area to add a 4" stroker kit to (for 408") then a cheap 318 with the same 4" stroke doesn't give up much at 390". add ally heads of your choice/budget along with cam, inlet...

    273 Rocker on 340

    I have a set on a 340 and they work fine. No grinding. Small cam/springs. I also have a set of Comp Cams Magnum rockers (not 5.9/5.2 Magnum) on a 318. They were $600 more than the 273’s. That’s a good looking cam. I have always liked my cams in that neighborhood. My 73 Duster has a 222 @.050...

    Does this prove David Vizard's 128 lsa formula ?

    How did you come up with a 75 HP loss?

    My cam numbers!

    How does this 270/280/108 cam compare to the Hughes one below? They never have it on their website but seemed to be a good runner in an almost stock 5.9 magnum a guy on YouTube had. Always was curious and the cam in this thread reminded of just based on some of the numbers.

    Does this prove David Vizard's 128 lsa formula ?

    318 Dyno Pull Here is a close to stock (sort of) 318 Magnum with a fresh top end and something like a 340 cam grind. .274 on 114 lobe centers. 253 Wheel Horse Power Add 75 HP for driveline loss. 253 + 75 = "328 HP" at crankshaft They are running 600 cfm Edelbrock. Pretty darn good...

    Best cam for the street both power & sound

    Yes just watch how terrible a low cr 318 with factory stall and highway gears goes. With mild cam, 272/272, Lift .454/.454 110 IC 62*, mild porting, 4bbl and duals. Look at all the time spent under 3,000 rpm, felt like forever. (Sarcasm)

    5.2/5.9 H.P build guesstimate

    How much can I bore the 318 to? I know it won’t be much but if I can get into the 330 CI range I’ll be happy

    318 4bbl upgrade. Help

    That SP2P manifold has really small runners so an excellent match to your engine. I ran that same manifold on my 70 Duster 318 back in the 80's with a 600 Holley, fresh valve job, and mild Comp 252 cam. The car had a 904 trans w/2.76 rear gearing. Was an excellent daily driver. Driving from San...

    Got a new Truck (new to me)

    For those that want to know, here is what a 1989 318 Roller Engine looks like inside: Bolt down the "Spider" and it's ready for the 318 intake of choices. Stock roller cam works well with 1406 Edelbrock 4 bbl carb. 302 factory closed chamber heads Factory 9.2:1 compression ratio Flat top...

    318 4bbl upgrade. Help

    It's probably a great match for a mild teener. Is the transmission shifting correctly?

    Not sure what to do

    How did putting trick flows and a roller cam (~size?) work on the 318? I ask, because I've got a mechanically sound 318 and a core 360 in the shop corner. What kind of rpm do you spin the stock bottom end up to?

    David Vizard - Which to prioritize - PORT FLOW or PORT VELOCITY?

    With a 2500 stall and 3.23 gears, dual plane and 650 carb? That cam is comps replacement 340 HP camshaft with only 218 @ 0.050 duration. Its got all the velocity it needs to fill the cylinders........

    Horsepower Estimate?

    That IQ52 motor was 297 hp. much smaller cam 260H (comparable to stock +/-) OP motor has significantly bigger cam, RPM intake, and probably comparable heads (IQ52 put 1.88/1.60 in 318 heads w/throat work), "650" Holley (IQ52: 1850 Holley) Sounds like Crackedback guestimate of 300-350 seems...

    Today is 3-18 of 2024. HAPPY 318 DAY!!

    I am not sure why anyone would be celebrating 318 day when you have 340 and 360 days available cheap. 318 day doesn't have enough daily compression available to be able to run a cam that makes the day torque down low, well, unless you put a 2800 day converter and run in 9n 4/10:rolleyes:

    David Vizard - Which to prioritize - PORT FLOW or PORT VELOCITY?

    If you go by these formulas for a second (say there in the ballpark) and calculate what's too big for a 318 to make peak power at 5,000 rpms the trick flows come out to be slightly lower than the lowest acceptable velocity. But if you put a set of trick flow on a 318 even with an rv cam it's...

    SBE 318 basic rebuild +CAM , INTAKE, HEADS, expectations?

    I don't know why were trying to make this 318 work you got a 440, at best get 318 running with minimum cost gather all the parts needed for the swap then swap, or just start the swap now and have it ready for spring. There's nothing wrong if you got a decent running 318 and add 4bbl cam headers...

    318 build suggestions?

    I don't see any evidence a 318 needs a lot more head, carb, cam etc. To make 400 hp. Look at those 400 hp 318 combos, it's basically headers, airgap, 750, 224-240 cam, 9.5-10.5:1 cr, heads that flow 220-230 cfms, you look at 400 hp 340/360 builds pretty much the same recipe. 400-450 hp...

    318 build suggestions?

    These guys did it with iron Magnum heads. A good set of alloy heads and a decent cam with a 4 barrel of course will get you there. I would spend the extra and run a roller. But...........................no you are adding to the budget and it's not a cheap build any more...

    318 build suggestions?

    I haven't dyno'd my 318 so i don't want to comment on parts... but i am here to watch the 318 haters go off :) BTW.. i went with trickflows on mine, the price is a little higher than other brands but i have more faith in that company to not send me garbage. Also went with Mancini roller...

    273/ 2 barrel camshaft options

    The 273's can ge a little more spendy to do. The pistons are more money that just off the shelf 318 pieces. The cam's and lifters are more because they aren't a generic off the shelf part. The rest is really the same. Pistons from Egge and Kanter (if they are still in business) and cam and...

    318 low-rpm performance ........... for the NEWBE

    I wanted to put up a post for 318 newbe's to show what happens to low-rpm torque with various cam sizes and compression ratios, so that we all don't have to keep going over the same old questions. And since almost everybody has, or has had, a 318, usually an 8/1 variant, with a stock 240* cam...

    Should I buy this 440?

    Mopar engineers thought dual exhaust was good for 20 HP on a '73 2 barrel 318. How much on a 440 that also had a hotter cam, 4 barrel, and slightly less restrictive manifolds?

    Sizing carburetor

    well, for better or worse, I have a 318 thats about to get a mild cam and probably a TQ. I do have a couple of AFBs on hand too, but at the moment one of those is Plan B. 800 cfm on a 318.. Hmmm....

    318 LA build log

    Just wanted to share the slow build of this 318. I know there are plenty of people and articles saying you can build this or that on a low budget, and we all love the idea of a cheap budget engine build. But the truth may be if you are buying a used engine that is not running, you going to find...

    Deciding on replacement intake (318, details in post)

    Dammit, for the cost of getting a stroker kit landed here I could as well find a 360 and Magnum heads are no easy find either. Looks like I may have to rethink the stubborn desire to keep it 318. Randomly stumbled across this whilst looking up the cam grind for the crane. Pokey! Old School...
