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...

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...

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...

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, 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...

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...

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...

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...

Hello all, on a mild performance street engine, how important is it for the retainer to fit over the whole spring? Please see the photos i have posted. I am fitting some single/damper springs i pulled off a 340 to a 318. They are 95 seat and 275 pound open pressure. The retainers they had when i...

I know this has been discussed before, but the more i read, the more conflicting information i see and the more confused i get. All i want to know is cup and ball p/rod lengths (for stock, unmachined engines) for 1. Correct p/rod length for solid cam and adjustable rockers (eg Crane). 2...

HI - i have what i bought as a solid (mechanical) cam. In good useable condition but no specs other than what i can measure from the lobe. ( but it looks only to have a gross lift of about 0.465. The seller didn't seem to know much, so is there any way of telling that a cam is hyd or solid? I...

I pulled the 318 a few weeks ago. It was a replacement engine (factory assembled 1993) but the cats date on the block is 84. No cast date on the heads. The engine is black in colour. Anyway, it has closed chamber heads -someone told me they were called "swirl chamber" heads. Normal cast flat...

hi, does anyone familiar with SB rod Part #s know what i should have here? I have just pulled down a 318, it was a late model replacement engine (cast 1984 and assembled 1993) and the rods are part # 3418645 (pressed pin and cast crank) The 1971 340 i have just pulled apart has the same...
