I got around to installing the new oil pan when I did my cam swap. I ran into the same issue as Fast340Cuda, even with swapping to the new 73+ style centerlink. I had to dent the pan about the same as he did to get it to clear the idler arm. I also had to dent a driverside header tube to...

I finally got my new cam installed. It took a bit longer than expected, the valve spring removal tool I had ended up failing and launching some springs. I had to go find another one to use. My new intake didn't fit, which is why I made the other thread asking about calculating head milling...

It sure is, at least in the pic of the combustion chamber. You can even see the carbon buildup on the sides of the cylinder showing the piston doesn't go up any higher. Like I said, I feel like they built this motor with whatever parts they had laying around.

If it's really 7.5:1, I guess it's time for a turbo!! I was told they were TRW 10:1 flat tops. I'm kind of thinking they just tossed whatever parts they had together. It's a 69 block from a Newport with LY rods, the trans was a 73 727 from a Charger with a 3600 stall converter, the heads...

I can't find it now, but I believe I read so.ething that said stock pistons on the base 440 were .090 in the hole and the HP 440s were closer to .020 in the hole. It's hard to tell from a borescope picture, but mine do look more than 90 thou down.

Was 8 to 1 even an option in 69? When I was looking before, I thought 80 thou was the furthest down they would be with a stock piston. I have no idea on the bottom end details other than it's a 69 block, forged crank and LY rods. It runs great and pulls hard so I never worried about it...

I don't think so, but hard to tell. That carbon is soft too, my borescope camera was leaving trails in it. Lol

Actually, looking at that pic, either the piston isn't sitting parallel to the deck, or I have a ton of carbon on that one side! Might run some Seafoam through this once its back together and running!

Thanks. I wasn't sure if there was a certain feature X distance from the deck surface that could be used as reference. I can check the head at least. The pistons are a good bit further in the hole than they should be for a stock bottom end, so I have no idea what the bottom end is...

Your way is probably more accurate, but I really didn't want to pull the heads. My headers are a nightmare to deal with on this thing.

I picked up a new Performer RPM intake and when I tried to install it, the bolts holes were all off 1/2 a hole in height. The M1 that came with the engine ended up going back on, which was also a challenge to get the bolts started, but eventually they all fit. I am assuming since the new...

I have a 440 in my Duster, it was an automatic and I just converted it to a 4 speed. Everything is a tight fit, headers make everything a tighter fit. For mine I had to go with a hydraulic clutch, I couldn't package the linkage for a manual clutch, my headers were in the way. I...

I just picked up the Hemi pan from 440source to replace my Moroso deep pan. I smacked the Moroso one on the ground enough times to rattle my nerves about cracking the pan. Here's a comparison pic. Moroso pan has exactly 3" of ground clearance on my car, the Hemi pan gives me 4.25". I...

I have ordered a new one with 230/236 @ 50, with an operating range of 1800-6000. I probably could have went 1 smaller even, but I think this one will work well. COMP Cams K21-224-4 COMP Cams Xtreme Energy Cam and Lifter Kits | Summit Racing

I'm more concerned with low end driveability that most amount of power, or high end power. Like I said, I still have a set of stock iron heads on it. I'm super happy with the power level it has now, just trying to bring it down into the 2-4k rpm range.

I do not, my distributor does not have it. I was running it with the timing locked out for years, now I let my EFI control the timing, but no vacuum advance.

Good Questions, no idea. Motor was in car when I got it, haven't touched it for 14 years until just now.

Good point, maybe I want to get the bigger Comp one that is still low rpm / street friendly. I will say, I do love the choppy rough idle I have now, it'll be a bummer to lose it.

I do not know my current cylinder pressure, but could check it. My compression ratio is 10-10.5:1 with a set of flat tops in it.

72 Duster, 10.5:1 440, 915 heads, 833, 3.91, 26" tire. It was built when it was an auto with a 28" tire and 3500 stall and was a bracket racer. Runs and drives great now, but lugs a bit and loads up under 2500 rpm. Trying to drop my highway cruise RPMs a bit, but not sure the current setup...

It was 108, I measured before and after to ensure it was the same, as it runs amazing as is. I am looking at one of these setups now, to make it more of a street pounder. 1969 DODGE COMP Cams K21-224-4 COMP Cams Xtreme Energy Cam and Lifter Kits | Summit Racing or the kit that comes with...

Thanks, it's should be 112 then, the grind number on the cam was 312-2. I'll hold off on the regear for now. I have no driveability complaints with it with a 4 speed and a 26" tire as long as I keep the revs above 2500 or so while cruising, below that it struggles. I used to have a 28...

Nope. They are as cast factory 915s. It pulls great to about 5800 or so.

I agree, I had some trouble finding this one, I called Crane's number, but they are apparently out of business and the number went to Edelbrock, which were useless. What do you have that shows it as a 108? Maybe I should have advanced it more then to bring the power band in sooner?

It's 108? The 3 bolt version they have is a 112. I degreed it in on a 108 when I put it back in.

I finally pulled my cam out to see what it is, it's an old Crane CCH-312-2-NC. It's a single bolt cam that I can't find any specs on it, but I have found the specs for the 3 bolt version, which I will guess are the same, since I measure the duration and lift and it matched. My question is...

Any chance you have a picture of the finished product?

Thanks. I have the DC K member as well, so it should be the same setup as yours. Was there a lot to clearance, or just a few swings with the hammer?

I have the old Mazzolini / Pro Parts semi fenderwell headers. They were massaged to clear my current steering, maybe the 73+ style will actually fit better. I'll have to get underneath and see. Based on pictures, it appears the 73+ center link is a little lower than the 72 style.

I saw that kit as well, thier oil pan by itself was a little cheaper than 440 Source as well. With how low my car sits, I like the idea of the thicker pan that 440 Source has. Glad to hear it fit!! I'm hoping to swap it out with the engine in the car. Not sure if it's doable because of...
