I just received my ARP Main stud set for Windage tray (ARP # 240-5501). And see that they have got their numbers wrong and have 5 studs for windage tray and 5 normal, when it should be 4 and 6. I looked through this forum and I see that there is a lot of info on this and has been an ongoing...

Hi all - can someone tell me what the -cc value refers to in the specs for the D.S.S Racing forged pistons? I am building a 1971 340 and wanting around 9.8 to 10.2:1 CR (any more than that, even with 98 octane, our fuel is sh** apparently in this country I've been told by foreigners). The two...

Hi all from Perth W.A., I have not posted a question for a while although I have spent many hours sifting through posts about 340 builds and pistons and rings and more... I am collecting parts for the build of a 1971 340 - it's all machined up ready for assembly (although the cast 1.88" int...

Hello, can anybody suggest some better springs, as an alternative to the Comp 995-16 (dual) I have bought? These were the recommended springs for the CC XE275HL-XE cam that I have installed in a 68 340 X head engine. Cam is a high lift hydraulic, 0.525/0.525. The springs are, on paper, ideal...

Hi there, Did a search for this and plenty of info on the 1969 Dart side markers but none about my dilemma. See the pictures of the two different bezel shapes for the REAR side markers on a 69 Dart. Now, I am in Australia and our 70 and 71 Valiant Hardtops are basically the same bodies as your...

Hi, I have bought a Mopar M1 inlet for my Valiant Dodge ute (pickup) 273 and it is the later style that uses the smaller thermostat housing, I think you call them water neck. We didn't get these later 318 intakes on our cars, Chrysler Australia stopped in 1982. These intakes are for 1990 on, I...

I did a search and found a post from someone who recommended Loctite 567. However this is absolutely not the ideal sealant. I am talking about the end exh manifold studs that go into the water jackets. Loctite 567 is not a thread locker and is classed as a low temp (max 150 degrees C) and low...

We say crown wheel, Americans say drive gear (or ring gear) and the service manual says to discard the old bolts when it is removed/replaced for service or ratio change or rebuild etc. Also I see there are many kits online with the new set of bolts. So I am wondering how much stress do these...

Hi all, I had the opportunity to be able to use a near new Rimac valve spring tester for a few days (the digital version). The Top Alcohol dragster paid A$1200 for it and it is a marvelous piece of equipment. After reading someone's complaint about Comp Cam valve springs not being true to...

Hi, I am sure this has been talked about before, can anyone guide me to where on this forum if possible? I can't seem to locate the information. The question is about how much to mill the head surfaces and inlet (intake) manifold for, say, one point extra CR. Is there a rule for LA engines...

I was wondering if anyone has had any experience with Cometic rear main crank seals? I just bought one from US ebay (I live in Australia), it was a good price I thought at US$27.50 and only $14.25 shipping. I bought it only because of the name, as I have seen and heard that Cometic make really...

Hi, I constantly get this problem when reading discussion threads where a poster has attached images: a large symbol from Photobucket saying something about enabling third party hosting. Can anyone explain why I often get this when obviously there would have been an image there originally? thanks

Hi all, I need to get the pinion preload reset on my 741 (it is too tight from a previous rebuild many years ago) and want to buy a set of shims to give to the diff shop. (BTW , I'm in Australia so not much info around on these 8.75's, and differential shops usually are not familiar with old...

Hi all, this post is similar to the one from Dodgedartconv however I need to know if anyone has experience in getting the stainless strip (which holds the fuzzy weather strip) onto the glass. Mine is very tight and just won't stay there, keeps popping out. The glass setting tape or whatever is...

What is the consensus from experienced engine builders on replacing the retainers of the piston gudgeon pins (wrist pins I think you call them ?). I am doing a budget rebuild on a 1967 273 with full floating rods. It will be a mild performance rebuild with mild solid cam, Weiand intake, headers...

Hi, I am trying to fit a Hemi pan (bought from 440Source) to a 440 that has ARP main studs fitted. But the back of the pan (the shallow end) is hitting on the rear main studs. This is my first B/RB engine build so not sure if this is a common problem? The engine was previously running a...

Hi, does anyone know for sure if this spring will work, please see pictures Does anyone know what tolerance value constitutes coil bind on a valve spring? Shown in picture is the spring I have installed and the valve is shown fully open - at max lift at the lobe (using a solid lifter for...

HI, I'm building my first Mopar engine, a 340. I'm not sure about a couple of things, hope someone has more knowledge. First the specs: it is a CC (Comp cams), high lift hydraulic cam. Grind/Part # XE275HL -10. The Gross valve lift (both intake and Exh) is 0.525, Lobe Separation 110...

Hi, I just bought an M1 Dual Plane inlet manifold. The thermostat hole and housing required is much smaller than all others I have seen. It is an LA, not a Magnum. Does anyone know where i can buy the correct vertical water neck (thermo housing) and the smaller thermostat? Maybe Rock Auto...

Hi, I have searched through many of the windage tray posts but can't see this info... I'm buttoning up the bottom end of my 340. Using stock pan and pickup and stock windage tray. However I have used Miloden main studs and their windage tray installation kit. But I can't remember if the tray...

I just put a 3.23 SureGrip (741 case) centre into my 340 Hardtop. This centre had previously had new carrier bearings fitted and the unit bench checked for normal operation. With the car on stands and no drive shaft fitted, I noticed some things, can anybody who knows these 8.75 centres tell me...

Hello, i am assembling an LA eng. There are two small core plugs at the front that go into the ends of the lifter oil gallery, they sit behind the cam thrust plate. The engine had previously been rebuilt, but i noticed that the previous mechanic had not put them in. I asked another mechanic, he...

Hello, i have a 69 Dart Hardtop (pillarless). All the interior is out. The rear parcel shelf looks like it has provision for retractable seat belts. There is a slot either side and what looks like a mounting point. Does anyone know if this was an option back in 68-69? Or have any pictures of...

Hi all, does anybody know if any of the luxury models of the Hardtop Darts (2door), with the 67-70 year body, had the interior rear courtesy lights on the C pillar? I am putting together my 70 Hardtop, its an Australian Valiant Hardtop but uses your 69 Dart Hardtop body. I am doing some mild...

Hello, i want to put a kit through my single piston calipers. All i can see on the internet is exchange calipers (remanufactered -need to give them your old ones or "core"). Being in Australia it is hard to find things like this for US vehicles. And sending heavy parcels to the US is very...

Hi, i'm installing a Miloden windage tray stud kit in my LA engine. On Caps #2 and #4. ARP main bolts on the other ones. When installing these 4 studs -should i use Loctite on the threads or not? Two people have told me yes, two others say no. Some say all the way down by hand until it bottoms...

Hello, i have a question for Chrysler die-hards - an administrator from another Mopar forum said that the terms "big block" and "small block" were originally Chev terms, coined by GM or Chev people. And that 'Chrysler correct' is actually what Chrysler use themselves, which is A engine (poly)...

Every SB mopar engine i have seen has had solid pushrods. Well, what i mean is, solid ends fitted to hollow tubes (non-oiling). The oil, as we know is pumped up through the head to ingeniously pressurise the rocker shaft and feed the rockers and top end, with the pool of oil in the rocker arm...

Hello, i am reassembling a 318 and using the book, "How To Rebuild Your Small Block Mopar" (by Larry Hofer and Dan____(?). They say when checking for wear on the rocker assembly, that there should be no more than 0.003" between rocker arm and shaft....(and rockers need replacing if...

Hello all, please see the pictures, are these Chrysler Solids? Someone told me they might be Slant 6 ones, but i found 16 of them from a purchase years ago, so i am wondering if they also used these in the 273 mechanical cam engines? If so, were they good lifters or did they have a weak spot in...
