Hang on fellas;
I fail to see a PCV problem here.
I suspect a T-slot problem, and a possible lack of bypass air, coupled with too much idle-timing.
And here's why;
my 367 has a 230/237/110 Hughes cam in it, .549/.571 [email protected];
and she will idle down to 550/500 pulling herself across the parking lot all afternoon, with
an old PCV pulled from the all-Mopar junkbox. And
with the T-slots slightly taller than wide, and
5* of idle-advance.
This is with a Commando manual trans (3.09low), and 3.55s, so the starter is 10.97 and there is NO fluid coupling.
My throttle blades have one hole drilled in each primary, to supply additional bypass air (about 3/32 each), in addition to what the PCV is supplying.
My idle-timing was determined by the T-slot setting to be 750 in Neutral@ 14*; or 700@12*.
The 5* I quoted above is done by electronic retard thru a dash-mounted, dial-back, timing-retard box. This is how you know when your T-slot exposure is set right; by the fact that it will do the above trick.
If you have an automatic you can get away with a lotta lotta errors, because the engine never sees much of a load until it gets to the stall-rpm. But with a manual trans, the tires are married to the engine, so your low-rpm tune has to be pretty dang close. And it all starts with the Transfer-slots and idle timing relationship.
I could be wrong,
it wouldn't be the first time, but I have seen it over and over and over;too much idle timing, has closed up the transfers, so the engine will not idle well even with the idle-mixture screws cranked way out. I learned this with the Mopar 292/292/108 cam, years ago.
I hope I'm wrong,
cuz I hate coming off like a know it all, way more than being wrong.
Just as a comparison;
My engine has been running the same ancient plastic
junk-box PCV since 1999. It has seen three different cams; beginning with
that 292/108 Mopar ([email protected] I believe), then
a Hughes HE 2430AL,([email protected]), and finally,
a Hughes HE3037AL, ([email protected])
The only difference was the size of the bypass holes and minor idle-timing changes, all;
same engine/same induction/same exhaust.
Yes the 223 was my favorite.
Yes the 292 was the least favorite, until it woke up at ~5000/42mph; then it screamed to 7200/60 mph, still in first gear,lol. Yeah, no,not the best idea I ever had. I ditched it before the end of the first summer.
I ran that 223* Hughes equipped iteration with several different carbs and intakes, and many different rear gears and at least one of every different Mopar 4-speeds 1x23 spline transmissions; hyup every one of them. Why? Because that 223* was a killer street cam, And I was searching for the killer gearing, to make a killer street combo..and I did,finally.
