This is about as far as you can go--cam/compression wise with a 318 and still have reasonable power and driveability. J.Rob P.S. Forgot to add--IMO 318 Wolf in Sheep's Clothing

Stock 318 with high rpm lifters. Gotta ask what is going on? If this 318 has been worked, then I don't know if those lifters are needed but as far ZDDP, I'd want a minimum of 800 ppm for stock cam, and maybe a bit higher, more like 1200 ppm if the valve spring pressures are high for a more...

What year, body,of magnum manifolds are you suggesting?

A 273 with any cam at the 340 Resto level or lower will be very responsive from just off idle to 5600 RPM. With the 4 speed stick, you will never be traveling at 850 RPM anytime in normal driving or you will pound the rod bearings out lugging it. Maybe 850 RPM with an Auto and 1800 RPM Stall...

if it's not making noise and no smoke, i would check compression to see how things are doing and i would 100% change the timing chain with that many miles. It all comes down to how well it was taken care of. Then normal maintenance **** like plugs/oil and all that.. That 318 might also have...

i collected a lot of money off of the unsuspecting with a 318 that just "had headers and a 4bbl" and looked to be the brother from another mother to that motor, right down to the parts store special chrome air cleaner. agree to the day two action. throw mellow little cam and intake at it, snap...

No that would be his recommended lsa, for street and or race. Say you like comps xe256h cam on 110 for your engine, to DV that choice basically you'd keep the same basic overlap and cut the cam on 105 lsa with that overlap and that would give you your new duration, probably something like a 250...

I've never seen any KB hyper pistons for a 318 bore/4" stroke. if you get an '85-up 318 or 318 magnum block you can run stock roller lifters on a hydraulic roller cam.....doing a 4" stroker, other than the "number" (392), there's no advantage to doing that over starting with an '89-up 360 or...

10 hp. 1978 NHRA specs 318, small heads, small cam, and same pistons 140 hp for 2 barrel, 150 hp for TQ.

Depending on top end, especially heads and cam. If you can get the small bore/long stroke to displace enough fuel and air over time (CFMs) the engine will rev, just a bigger bore shorter is more suited to higher rpms.

That is a good one. Too bad it's a Comp.

You can put regular 318 heads on it, just make sure the Springs are right for the cam if it's not stock. As for the stuck valve in the 360 heads if it didn't hit the Piston it should be okay but if it did it's bent. You'll want to clean that guide out and put a new valve in it and either touch...

I have an 84 black 318 here that has a roller cam with fuel pump.

I did the swap on my boat, had a Chevy 350 in it…. But gained almost 5mph in a 4500 pound boat. So it’s worth something….

Have been chancing my tail on my 318 engine not running correctly. Had a well known Mopar engine rebuilder[Wayne Hyrowick] rebuild my engine ,Keith Black #167 pistons, .30 over , Hastings Piston rings, 30 over, Comp Cam 20-223-3 and matching springs, lifters, alum. intake, 4 barrel Holley carb...

Too much cam for a low compression 318 .

complete bull piss

I would put that cam in the garbage can and make myself happy. If I went through the trouble of building a 318, it would get at least a 340 cam.

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.

Isn't this cam kinda big for a 318 with a 9.2:1 CR? 224* / 230* duration @ 0.050"? Just asking

Pa-lease!!!

wait a minute..."Bolt ons" He has an intake, a 600 cfm carb, mild cam and headers. might not make 300 hp with a 318?

If you say so. It works great for me but just like OP I am not a bracket racer or a number chaser. Make of that what you wish.

318 cams are wanting a bit. A 360 cam is likely going to perk it up a bit and still keep a smooth idle. A 340 cam may introduce a bit of lope to the idle. This is really where the tune comes into play.

Yeah, a magnum build would be cool but $200 for the short block, I got just have to put heads on it and cash flow is tight at the moment!

245 hp is net hp, when talking built hp most are talking in dyno trim, which at very least is no accessories best tune, generally headers. Most engines in dyno trim are at least 30 + hp gross above net. 25 degrees ain't a small cam upgrade, generally we consider about a 5 degree bump as the...

You really think so? I thought it was fairly responsive "for what it was".

Funny you mention that story/experience, I am getting ready to do something similar since i wiped a lobe last week. I hope it works as positive as yours did!

...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, but I could...

Your first step in 318 cam choice is probably going to be dealing with the exhaust rotators. Sometimes it’s not a problem with the valve locks being the same as the intakes and only needing to change the retainers, otherwise it is a problem. That’s a good choice on the Howard’s cam, though. Are...
