I think the concern here is not the numbers themselves, as if he is thinking they are too low, but why there is 15 psi fluctuation at hot idle, if I read that correctly. If it's steady at cold idle and then gets the big swings at hot, I would be surprised if it was air in the line. It might just...

It's quite possible we are both right. You are 100% correct its moist there, I just would have expected it to leave at least some residue, unless of course its just burning off. I just know I had a pretty substantial amount build up when I uh.. forgot to teflon my bolts lol

The puddle would have formed between the edge of the manifold and cylinder head then as well rather then only spilling over. OP should put some good teflon tape on his bolts; my car did the exact same thing before I did.

Iv tuned both before with good results, just wasn't sure if the double pumper would be too much. While I do firmly recommend edelbrocks to daily drivers and people starting out, will probably go with the DP since I can get more out of it most likely

Hey guys, motor is a 73 318, valve-train redone with a XE256H, weiand stealth manifold, cope street/strip 904 with a 2500 stall, msd ignition, headers, 7 1/4 with 2.76's. Plan on swapping to any 8 3/4 with 3.91's mid summer. Looking to just go ahead and get a carb that will work for me now and...

Nothing is stuck. The inlet itself is leaking, it isn't seated correctly

No idea what it was sucking on but I did discovered it happens non-stop while in gear, at 650 rpm 14 inches of vacuum and then intermittently at the 870 rpm at 17 inches. The PCV valve is a BWD one I believe but it wasn't the part making the noise because I completely disconnected it to...

Finally got around to running through all my gaskets/vacuum lines/venturis/etc. and have determined it is the pcv circuit in the carb making the sound just in case you guys were curious

Not sure what you mean by T-port sync. Doesn't have any hesitations what-so-ever by what I can tell but I have yet to really rag her out yet.

Wasn't paying too close attention while it was warming up because I was gathering my timing light, vac gauge, etc. It was happening when it was fully warmed up though. Say if that was the issue, whats the fix for it? or is it just the way it is? Again to clarify, this occurrence has zero effect...

Got an interesting one for you guys today, completely stumped the edelbrock carb techs. So put a 1405 eddy on my 318 yesterday and was tuning it and noticed occasionally it would make a sound such as if you were sucking the last little bit of drink using a straw. Happened maybe every minute or...

Depends what the rest of your build is going to be like. You could just get an eddy 1406 (since they are very simple to tune and get accustomed to) or a holley double pumper and really let that motor scream. The carb that goes on should be directed correlated to how aggressive the rest of the...

Do a 2.25 inch exhaust, that engine is not making nearly enough power to warrant 2.5. As a general rule, more free flowing exhausts = more horsepower/top end and a more restrictive exhaust = more low end torque. Example, 2.5 in will support 400 horsepower. If you installed a 3 in, you'd get more...

Interesting perspective to hear. On most of these threads a lot of people recommend it

If you talk to me enough you will learn that hitting my head against the wall over this kind of stuff is one of my worst traits haha very much appreciate your input!

Ah, late night, must have swapped it in my head haha

Thanks for the info! Now just to determine whether that Castrol is a true synthetic haha

In reference to Marks post. Lets say that you wanted more than the 25 Psi you were getting from 20w-50; psi being a measurement of resistance, would it not go down if you switch to a lower weight oil?

Like I said on that other thread iv got going now, the oil I currently use is Castrol Edge 5w-50 synthetic, its about $10 a quart. However by what you said on my other thread, it seems as though it may not be a true synthetic and more prone to possible break down.

Yeah forgot that, sorry. 79,000 miles, low wear.

Making the transition to VR1 in my 318 and need some opinions here. Engine is moderately modified, all top end. Currently with 5w50 gets ~50 psi at start up/25 at idle when hot. Generally a cozy 90-100* outside, engine runs at 180-195 and probably would be driving about 70 miles a week with some...

Yeah I was aware of that one; partially the reason I started this thread was to work out all/if any more undesirable traits of the oil. Thanks to you all I think iv got a pretty good picture of what I am working with though

Yeah I got you. I was figuring this could quite possibly be me splitting hairs as Iv been known to do lol The Castrol Edge I use is a full synthetic and designed specifically for classic cars. The other thing I was thinking about was VR1 but that gets into 10w30 vs. 20w50

Lotta good info there, thanks! Main reason I ask is I had primarily been using Castrol Edge 5w-50 and was curious if maybe a change was in order.

Well figured there was a little more too it such as if the oil contains VI or VII modifiers or if they could be stabilized to such as degree that is was kinda a non-issue.

Hey Guys! So read something the other day that I'd never heard before and wanted to see if anyone here had any insight about it. Essentially it was saying that the greater the difference between the oil's hot and cold weights, the more quickly it would break down and the more likely it was to...

Any info and knowledge is always welcome! Thanks for the link man!

Yeah I hear you man. Might just build something out of that on the side and sell... Or put it in my jeep and have lopeist of grand Cherokees lol

Very good point about balancing the flex plate instead; would make it that much easier. That is an idea I had rattling around in my head though, stroking the 318. That's why I was curious how much you can bore them without getting a bit thin on the side walls.

Okay cool! And I believe I do. I know that if I want to use my current converter I need to get a weight kit for it; but do explain if you don't mind. Wouldn't hurt to make sure I have it correctly understood.
