Right now there are two issues I am facing: stumble right off idle and major bog when secondaries open. Idle mixture screws set for highest vacuum (21" Hg). Accelerator pump in either position did not affect situation. Metering rods adjusted 2 rotations from bottomed out. Air valve wound up...

Used 318 roller cam and hyd roller lifters out of '85 or '86 Chrysler. $175 shipping included to US contiguous. Perhaps a good candidate for an Oregon Cam performance regrind? Since no one was interested in the complete 318 I've been offering I decided maybe someone some of semi-desirable...

I have a 65 dart GT with a .030 over bore '68 318 with wiseco 10:1 pistons, comp xe274 H cam, dual exhaust (stock exhaust manifolds), dual plane weiand with 600 cfm edelbrock, '73 stock electronic ignition, balanced, high perf valve job, ported heads, carefully timed etc. and it is very fast...

Nothing will convince people to change their minds, if they aren't open to receiving, evaluating, and acknowledging new information. Some people are just stuck in their ways and perceive everything that doesn't 100% agree with them as some kind of personal attack. They just go into fight mode...

Friend of mine raced dirt track, ran a 318 with 340 heads. Fastest car on the track.

j heads on a 318 doze one fine job! have had 2 and both were screamers!!

What power level you trying to get? Sounds like streetaability is important to you so probably 0.8 to 0.9+ hp per cid about 256-290 hp. Not really that hard there's slightly different ways to get there, mainly different head and cam combos, less flow more cam, more under .450/.500" flow less...

Ill just say the 70s 318 is cheap or free for a reason...:)

Power loss due to switch to aluminum heads and higher thermal conductivity rate has been debunked. Above about 2200 RPM the combustion cycles too quickly for any appreciable heat transfer to occur into the cylinder head; vast majority of heat going into the head comes from the exhaust valves...

Correct. But how far does he want to go and how much money does he want to spend on a 318? Unless he's going to add a roller cam, some exotic heads, turbo or blower, he's not going to make a huge difference from what he has now. That's why I recommended sticking with what he has.

That's more believeable than the Motor Trend 318 already and I don't even know the rest of the details.

...wrote it; In the same sentence, the piston is at the top, then it is coming up. So, wth stroke is it on at what time? Looking at the factory 318 cam specs, with the cam installed 4* advanced, the intake should be opening at about 12* before TDC and closing 48* After Bottom dead center...

I put one in a 7.5 to 1 compression 440. Ported 452 heads. CH4B intake, 3310, Made 415hp and 465 torque on the dyno.

Well my point is/was ( with regard to the OP) use the stock 318 cam because installing a performance cam into an otherwise stock early 70s smogger 318 doesnt gan you much in the top end... I beleive its mainly because of the small port heads and small valves,

All that's true. What's also true is, not everyone wants a 360 in every application. THe 318 can get some really good mileage that's tough to get from a 360.

So you want a lopey idle? >If you have a goodly amount of cylinder pressure, You may actually be able to install a real cam, and do what everybody else does, namely, install a higher stall convertor, to eliminate any soft bottom that may come with the cam. But a real cam, will need real...

I know it's not cheap but I hope you get a chance to dyno it. Sounds like a fun combo.

idk, the crossword? research 318 cam specs? go out to the garden and pick veggies? call around town looking for a set of magnum rings that apparently nobody has sitting on a shelf... i mean, lots of things... woah. wait. what was i saying? man i am hungry all of a sudden. anybody else want a sub?

Haha.... we said the same thing at almost the same time ;)
