Nope, it's truly dual plane, which you can just make out if you look closely at the photo.

How about... ... we work out a low-production licensing agreement, and I get us a low cost prototyping quote? I have a friend with a idle waterjet machine. If the design lends itself to being cut this way, or even rough cut, it could cut costs significantly for an initial prototype or...

Heh... No rush... just wondering if your brand maybe does a better job than most.

Yeah but... Good to know... but I have to make a decision on a new water pump for this motor very soon, and I'm trying to decide which way to go. If I upgrade to the reverse rotation serp stuff, I might as well use the best pieces I can, right? (HO pump, Dmax or 20" fan) Esp since I tend to...

He does. See my earlier reply. ... 2100 pop, all within 50 psi. Thing is, if you buy a new set and pop testing shows them to be inadequately balanced, you then have to spend even more to have them balanced. Hence my preference for a high-quality reman set from a reliable vendor.

More infoz plz... Hey, so as soon as you get outta the penalty box or whatever ):h , could you supply some specifics on exactly which Teflon paste you're using here? Big thanks.

ARP makes this point very clear in their literature also. I'm not sure how long the various grades of loctite take to set up, but this approach sounds problematic to me. Seems like a soft or semi soft slow-setting sealant on the threads would be best. I wonder how to test exactly what the...

I believe that the other potential benefits of using a dual plane have to do with lengthening the runners overall, and equalizing the lengths between them somewhat. Isn't there some buffering acheived between adjacent cylinders drawing from a common plenum as well ? Does anyone know which...

Right you are. Indeed. Here are the answers direct from Tim: Availability depends on cores returned, 90% are Bosch. Others may be avail by request. Replacement nozzles are US Diesel. Pop pressure is set to 2100 PSI, within 50 PSI across the set. Thanks Tim! Well sure, but...

Yep. My thinking exactly. Yet, these both came off 6.2NA motors. And while I understand the general thinking behind each type, I have NO idea what the general may have had in mind when deciding to use one or the other at different times. Did any 6.5TD's ever use a dual plane?

Okay, are these the inj's in question? http://www.accuratediesel.com/shop/19.html If so, does anyone know what they actually are, how closely they're balanced, and what the pop pressure is? I'd love to give them my business, but frankly, it really bugs me when the information needed to...

$127 ?? Damn, that's a great price. I think Mahle/Clevite "owns" Perfect Circle now, or at least the name. Or in some way, they're all rolled up in bed together.

Two manifolds, both from non-egr 6.2 motors. This open plenum unit is from a 1990 J code: This dual plane unit came off of a 1985 J code Sub with a 1999 GM crate motor: When and why were each type used on which motors? Any idea? Thoughts on which might be...

Hoo boy... That must've taken some time. When you say "washed", do mean with a spray bottle? And then wiping everything down by hand? I have to do something similar this week, and really, REALLY not looking forward to it.

Well, THAT's great news... ! Whoa... I'm so glad I asked. And THANK YOU SO MUCH for the breakdown, MissyGW. I'd be overjoyed to be able to use a hi-flow water pump let alone the Dmax fan. Sooo... if I get all the brackets and peripherals from a '97 thru... 2001? then the alt is on...

Okay, after reading everyone's posts about installing the 21" Dmax fan, and how it yields TOO MUCH cooling... I have to admit I'm a little green. Wondering what the best setup would be for an older body style truck. I'm assuming it's waaaay too much work to adapt the later-model serpentine...

That one crossed my mind too... but then I thought, how does a mid-90's 141 block ever leave Flint with a bore smaller than 4.055? I'd already have taken a much closer measurement of the block, but it's at the machine shop, headed for the scrap pile. I think I found the problem though... I'd...

Thanks VERY much for the tip. Northern Auto Parts lists theirs as Clevite, not Mahle. Any idea how to distinguish between the Mahle and Silvolite units visually? Can you elaborate on what you've found lacking in the Silvolites? (Just curious.) Personally, I've had poor experiences with...

Not sure I get this. So some 83 model year trucks might have gotten the higher nickel blocks also? First time I've heard that. Sure would love to see some definitive sources on changes to the castings in the 80's. TDP has a fairly detailed history of the later block castings, but I've seen...

Thanks for the correction. I've been puzzling over that a bit. The Goodwrench motor (506 6.5 block) that was dealer-installed in the '85 Sub has pistons that measure 4.020 in dia, INCLUDING the carbon buildup at the top edge. Bores measured about 4.030 with dial calipers, probably a little...
