It is a CLoydes Hex A Just chain .They said a double chain on the hexajust will not fit on the Gen 6 block. I did some research on them with some other engine builders and they haven't had any problems ..Most of them told me they used the cheaper ones anyway ? Theres not much spring pressure on the motors anyway. The Hexajust makes it easy to degree in the cam.Just personal preference I guess?On my Scarab with the blown motor The chain had 170 hours on it and its still running in another motor I built and sold in the Scarab .I have had good luck with the single chain Hexajust on the big blocks.



When Linster made his post on the Rollmaster someone came up with a old notice about them having a problem . He called and also did some research on them and found it was with a blown small block crank . Only one!! So they withdrew the notice and said it was not the chain[crank gear].You are in good hands with Linnie

Funny... my engines came back from Charlotte, NC with TWO oil galley plugs drilled out as well. Not really sure if it was good or bad either, but we figured that using one plug with a hole in it was enough for oiling. We also used a Cloyes Hex Adjust as well, but I think it was a double roller.

Yes, that was me on the timing chain gear, but I still think Linster sounds like he's a good man, and a good engine builder.

Sounds to me like these two need to get a new thread and maybe a woman or two. Even though they both sound like they know a hella lot more than me.

Kamma my plugs looked like they were pre drilled . I dont think they drilled them up there.It had 3 different kinds in them. I asked a few people and they said they have seen it come in the higher HP stuff and also in the marine motors from the factory, But it was 50/50.On my small block drag stuff I would drill the hole in the block face. I thinking was with a high voulume pump that one hole should lube it enough.

Does Anybody else have any experance with this?






SpeedJunkie you have any rusted threadless head bolts laying around

The two plugs behind the cam gear that feed the lifters have the small holes in them from GM. The main galley does not. In the GM high performance catalog, a few years back it stated the were installed to keep an air lock from occuring in these runners. All old Gen 4 engines never had them. I keep them in since it does not seem to hurt. I think it helps oiling if you have a roller bearing behind the cam sprocket.

I found this out on my first Gen 5 rebuild. I did not notice the holes and reinstalled all the plugs after the block got out of the shop. When priming the engine in the boat I noticed a bunch of oil in the bildge. One of these with the holes was installed in the rear cam passage. After pulling the engine and correcting the problem, that is what I found out.

Messy mistake.

Yea I know I spent too much time on the oil pump

The intake does look funny doesn't it. I bet a few people would not notice whats wrong.

Bob 300 hp where your at now on HP?


Thanks linnie on the Info.Let me know how your dynoing goes .Good Luck

Ck this out I was cleaning the drive hubs up and found this on thats Bad You might want to ck yalls when ya tear it down . The splines are all mashed to a sharp point . Looks like it was fixing to strip out .Ill have to ck the shaft on the drive when I get them back from BMax.I did not know I had a problem


The last picture is the bad one .

[Strip Poker 388]

I have one short block together. The crank had .0075 end play and the main bearings had .0025-0027 and the rear had .0035..

The rods came up between .0025 and .003.

I also have the ballance cards I will post also.



Also on the Keith Eichert oil pan the Fel pro one piece gasket had a lip on the rear that had to be trimmed for the pan to sit down on the gasket . The old gasket was done the same way.I will get a pick on the next motor .

Here are some more picks of my heads before the Valve jobs. Like I said I did not do a lot to the runners .Here is some of the combustion chambers . They came up to 122 cc's after the new valves ,valve job and cutting just .We cut them 007 of all 4 heads just to get them flat .The
