I am running a FiTech EFI dual 4 setup and control the fuel with it. At idle my afr is 14 to 1. At cruise not under boost I go to 13 to 1. When under boost it is 11 to 1. This is a pretty rich setup that helps to cool everything down. I also run my temps at 156 degrees. The only time it goes...

I started out at 28 degrees. I slowly upped 1 degree at a time to the 31 degrees. I even drove it trying to get a ping out of it and never did. The engine just seems happiest at 31 degrees. I even upped the boost to 12 lbs once and got on it for a couple of short bursts. The only thing that did...

The retorquing is something I was thinking of doing not what I have done in the past. A straight edge goes on it tomorrow, I didn't get a chance to look at it today. Life got in the way. I did put 5 gallons of fresh gas in before I started it in April. I did start it a couple of times during...

None of the plugs were damaged. One was fouled a little. I run my fuel mixture a little on the rich side to start with and that is what 7 of the plugs showed. It was just #6 that was fouled and that was the one that the gasket showed as the worst. Jack

After lots of thought I have decided what I am going to do. I decide to go with the Fel Pro 1008 gaskets again. Reasons for this. I can get them locally, they lasted 11 years the first time, I do not have to remove the engine to have it resurfaced. That's a big one. Don't have to have the heads...

There is something else that I failed to mention for some reason. I think it is important in this discussion. When I was loosening the head bolts on both sides I could not believe how easy it was to turn some of them. I am used to really having to reef on the strongbar to loosen head bolts. Some...

I don't pull any timing. I have my timing locked at 31 degrees. It seems to work well for this engine. Remember it has been together for 11 years and about 1500 miles per year. And I drive it, not baby it, just ask the wife. lol Jack

Most of the time I am right at 9 lbs of boost when I get on it. Jack

I just came back in from taking the drivers side head off. It was pretty much the same story as the passenger side, just not as bad. It looks like I am going to get out of this with just some gaskets. I did check into what my pressures should be and it looks like with an 8.2 to 1 engine like I...

Strange, I go to Summit and they all say special order. Mancini and Jegs have them as well though. Jack

I was just checking out the cometics. There is a 4 week wait at minimum. That's nuts. I wonder what other options there are? Jack

Yes they were. Jack

It's going to take somebody that knows more than me to answer that question. lol Jack

I'm guessing a little bit of oil was getting in from the lifter valley. There was light blue in the exhaust but not a lot like you would get with rings being worn out. I don't know what the cylinder pressure should be in an 8 to 1 compression engine, but what I am thinking might be a...

Number 8 has me scratching my head as well. Jack

Here are my thoughts. It appears that #6 has just completely pushed the head gasket out. Number #4 is not far behind. Looking at the pressures again I would say that #7 is headed that way as well. The cylinder walls still have crosshatch on them and I didn't see any scratches. There are no...

I got it taken apart today. Here are the photos. Jack I didn't see anything obvious damage wise. The one thing I really noticed was how much cleaner #6 was compared to the other pistons. There was no scoring of the cylinder walls and no ring ridge. The cam lobes looked great. #6 here is...

That was 11 years ago, (I just looked it up), Rob. My memory does not recall the type of rings, only that they were a softer metal than what a n/a engine would use, but that only applied to the compression rings. Jack

My first thought when this started was possibly a bad valve seal somewhere. Jack

I am going to find out tomorrow. I am going to pull the top off the engine. That will tell me a lot as to what is going on. Jack

I'm an old retired guy. I got nothing else to do. lol Jack

If I'm going to replace a head gasket I might as well do it all. It is still a job I can do in 2 or 3 days. Jack

I can't remember what the initial compressions were, that was 11 years ago. #8 had me scratching my head as well. Did it again and was the same. Jack

I started my 340 up this spring and noticed a **** load of blow by. I finally got around to doing some tests on it today. Compression is all over the map. There is light blue smoke coming out of the tail pipes. And you can see the amount of blow by in the video. The plug check showed all...

Finally got the old girl out after a long winters nap. Took it to get a little fresh gas and all seemed well. Now just want a little warmer and sunny weather. Jack

I had covid around Christmas. I didn't take anything for it. I found it was nothing special except for the extremely sore throat and it was gone as far as symptoms in a week but I tested positive for 17 days total. I had the first 2 vaccine shots and the wife had 3. Neither of us will ever have...

I did check that and what I found was, the belt got tighter for sure, but I still had lots of play in the belt. Maybe a 1/2 inch from side to side. It starts out cold at about 3/4 to an inch of play. When I looked closely at the broken shaft I noticed what looked like air bubbles in the shaft...

With that much snow Aaron, I think the pain is going to be a little higher than your ***. Jack

I just had this photo sent to me. It is from Cape Breton, Nova Scotia. This is the same storm that @jimjimjimmy is getting. I am told all the snow in this photo is from this one storm that is expected to continue for at least another day. Jack

To my knowledge mine has never been in a mag but I know a couple of people that have A-bodies that should be in mags. One is a member here, @jimjimjimmy has a 70 Duster that is a real head turner and neck breaker. Another friend has a 65 Dart that is very nice and has won many trophy's at...
