I know, but meant mores as comparing the tq curves of one another, 318 would be lower overall tq numbers and probably at a slightly higher rpm, but still useful see how those cams effect the tq curve and wouldn't be to hard to imagine how they would compare to the xe262h tq curve in the 318...

Problem is there's very little consensus when it comes to 273/318 performance, most think you shouldn't touch them ever 360/408 only way to go, then there's the cr and velocity doomsayers.

good used lifters for 273, 318, 340 and 360 for use with solid flat-tappet cams. i believe they came from a 273, unsure. very lightweight. if you plan on using a mechanical cam and want to avoid lifter failure, you need these. they were produced back when lifter damage was almost unheard of...

@MOPAROFFICIAL Hi, i have read this thread but not quite sure if I understand everything correctly. I want to buy these Speedmaster heads: Mopar Chrysler SB 318 360 170cc 65cc Hydraulic Roller Assembled Cylinder Heads My cam is Comp cams 20-746-9. Are these heads p&p for Mag engine with...

100%, to me the only reasons not build a 318 is if rpms/gear/stall is too much for you for hp/performance level you want. Not just for the 318 that basically goes for any engine.

Yeah I figured as much. He lamented the fact that no one here ever wanted to talk about doing up 318's. I'd imagine those cams are well into the 300+ duration figures.

I'm not disagreeing. I live both styles of cams. I collect cams and off the shelf definitely have potential that's for sure. However I just feel more comfortable knowing that it doesn't cost a penny more to have a cam company take time and find something that is best suited for me. Hell Jim at...

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...

The “no matter what certain to make a performance improvement in a high geared low compression 318.” Works well with any of the 318 port intakes. Mile-A-Mor Cam [3901M] - $246.00 : ISKY Racing Cams, Do It Right

Thats what I am thinking

For anyone else who may be seeking 318 exhaust valves to replace the rotator keeper valves in 302 heads, here's some info that should help: The following three part numbers are all the same valve. They are easily found with an online search. Qualcast 10-1329 SBI 01329 Melling V1329 Their...

I was under the impression the 5.2 and 5.9 Magnum roller cams were a bit hotter than the LA roller cam, which did, in fact look pretty near identical to the FT pre- LA roller cam. I've asked in a few places if the LA roller version at least had faster ramps to take advantage of the rollers, but...

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.

I think you’d like this cam if you have 2.94 or 3.23 gears. From what I’ve seen lately, Isky still has a high success rate for cam and lifter break in if you get their lifters, although I hear Rhoades non leak down lifters are good, too. It’d work really well with a Holley Street Dominator...

I agree on all your points. Considering this van engine is a stockish 318 that would be pressed to spin to 5k rpm, a dyno of this engine would give more usable info if started at a lower rpm. Even then we don't get much info about part throttle driveability from dyno testing.

I run it long enough to where it can idle without stalling, then drive it easy until it is up to temperature. I don't have a choke so it is all foot and feather until it runs steady. These flat tappet cams need varying rpms for proper oiling. No flat tappet engine will like long idling periods...

He may be retired by now but the guy that runs Oregon Cam gives great advice. His name slips my mind right now. He’s a wealth of information. Oregon Cam is still in business.

2000 rpm at 75? Don't use a cam with any performance designed into it. With the OD and those gears most any cam but a stock spec one will be too much. (generally speaking)

On my 73 318 block I have cast iron heads 2843675. These were used on 67 318s and 68-69 273s with 2-bbl carbs. 1.78 intake/1.50 exhaust. Small chambers 62-64cc, small ports. I had Basko Engines in Gilbert AZ open valves to 1.94/1.60, polish bowls, used lightweight valves, 320 springs. They did...

Agree. I like to compare a 318 to a 327 chevy. There were two barrel, low compression 327s, usually in a full size impala with no gear, and a powerglide. They couldn't pull a fat girl off a tricycle. The 318 is very similar to that 327, a low-po workhorse, with no pretense of performance, so no...

Not saying cr has nothing to do with but additional airflow is also help making low end tq, plus the low cr 318 with xe262h cam is making 45 tq over stock cam at 3000 rpm to with zero cr help and obviously the 4bbl vs 2bbl helps too. That 10.5:1 ported EQ 247/247 477 hp has the strongest curve...

I would personally take second look at Summit, specifically the 6900/6901 cams. A .480 lift is pretty big for an otherwise stock, low compression 318. Those two I mentioned above have been proven to "wake up" a 318 without going overboard and also without requiring lots of other performance...

What I was trying to show with all the dyno is that even with various cams in 318/340/360 from stock to fairly wild all made decent torque at 3000 rpm for sure, decent evidence that at 2500 rpm most if not all still doing ok, less evidence but even at 2000 rpm all seems good especially is...

You can edit. Nice blower motor but nothing to do with 318 port mismatch. :poke: :lol:

For sale is a set of small block ball / cup pushrods. These allow you to use the 273 style of ductile iron adjustable rocker with a hydraulic flat tappet cam. They can be used in any Dodge, Plymouth, Chrysler small block 273, 318, 340, 360 with adjustable rockers. I believe these were from...

Not having studied the 300 series cars that much what engines did they have in them that had adjustable rockers? 273 or 318 poly, 413?

The engine did have a solid cam in it when I bought it. I like the idea of a quiet maintenance free cam, if I can have it. The cam That was in it had the following stamps on it. I actually considered putting hydraulics on it. I have not determined the profile of it yet. I can only assume its a...

I don't care if this build will/has moved goal post, the flow numbers they gotten out of the 318 parts can easily reach the 318 HP goal, I'd rather them do a zero deck 318 build, and get as many cams and top end parts they can a dyno every combo under the sun.

Any cam you install (unless it is real close to stock specs) should be checked for clearances.
