I have a single J head laying on my bench taking up space. It was ran on my 340 for about 10 miles until the other head dropped a valve and got beat beyond repair. It has new guides, 2.02/160 seats, and some minor gasket matching port work done. I am asking $150 plus shipping, or make me an...

I just need to rant for a moment. I posted a question a long time ago (see "lights flicker and gauge jumps around???"). So now I have some dumbass telling me that it is my fault because I chose to upgrade something on my car. First of all I never asked for criticism about what I did. Second...

Yesterday I drove my 67 D200 truck to my shop in the morning and it was running great. I fired it up to go home and noticed it was running rough. It sounds like it is not firing on all cylinders. It is a fresh rebuild to stock specs. The motor has about 100 miles on it now. It is a 67 383...

My wood hauling/ snow plowing truck has a 1965 383 motor with the points ignition. I was driving it today and it was starting and running good until I got home this afternoon. I backed into the wood shed and unloaded it and when I went to start it again it fired up for about 3 seconds and died...

Motor is a 340 with cast iron J heads. I have a set of adjustable rockers from a 273 that I was going to use. The rocker shafts that were originally with the 273 rockers were worn noticeability so I swapped them with a set of shafts that had the stamped rockers. I put everything together and...

My wood hauling truck has a 1965 383 engine with 727 Tranny in it now but the motor is getting weak. I have a 440 from a motor home that is either a 1975 or 76 that I want to swap out. Will the torque converter from the 383 work with the 440 or are they balanced different? I just had the Tranny...

I am putting my 340 back together finally. When I disassembled the engine there wasn't an oiling tab for the timing chain and the bolt with the oil hole was missing and a regular bolt was in its place. I have heard mixed opinions about the oiling bolt and the tab. How important are they? Should...

Today is my Dad's birthday. Sadly he passed away 2 years 10 months ago as a result of an ATV accident. I am sitting in the chair at the tattoo shop as I type this getting a new tattoo in memory of him. I will post a pic when done. He is the reason I love Mopar. I remember riding around in his 71...

Why is it so hard for some people to dim their headlights? There always seems to be some people that can't remember to dim their lights when they get passed on a 4 lane highway. Then after they are behind me for a few miles they finally figure it out. Once I get passed them and I turn my brights...

My car is a 74 Duster with a 360. I am having issues with the voltage gauge bouncing and the lights flickering. The engine bay has been completely rewired with all new wiring, all of the lights have been wired with relays, headlights are converted to H4 halogen, msd 6al box with blaster coil...

I know there are threads discussing the main bolts already but I can't find the one that said where to buy new main bolts that work with a windage tray. I purchased ARP main studs only to find out after the fact that I should line hone the mains with studs. I already have the cam bearings, oil...

Can someone help me decode this 340? I know the block is a 69 but I am curious what it would have came out of. The casting date is 7-14-69. The numbers on the oil pan rail are 0B183694 I believe, they are hard to make out. The numbers on the pad by the head are FW340P30100285. The casting...

I am in the process of gathering parts for my 340 to put it back together again. It dropped a valve shortly after the breakin because of a stupid mistake on my part. Since it has minimal run time on it would it be ok to use the piston rings again? I am planning on honing the cylinders. The...

I am starting to gather parts to build my 340. The block is a 69 bored .030. I have my eye on some TRW 2316 pistons from another member here. I will either be using a set of X heads or some worked over J heads with 2.02/1.60 valves. I have an Edelbrock RPM Airgap intake and Holley 750 carb...

Does anyone have a set of .030 flattop 340 pistons they would want to sell? I am looking for something in the 9.5:1-10.5:1 compression ratio. I know I can buy new pistons but I figured I would see if anyone had a set laying around that they would want to get rid of. I have a 70 340 and I will...

It's not an A body but I was hoping you guys could help. I am having troubles with my truck. The running gear is from a 1977 W250 and the body is a 1986 D150. The brakes have not been right since I bought it this summer. I replaced both front calipers because they were sticking. I bled them...

I have a Edelbrock 1406 600cfm carb. I was wondering if it will be ok for my motor. The motor is a 67 383 out of my 67 D200 camper special with auto tranny. I honed the cylinders, reringed the pistons, put new bearings in, and put a cast iron 4bbl intake on it, the heads are 516 castings, the...

I am having issues with my Duster. When driving at night the lights constantly flicker lightly and the voltage gauge bounces from 14-16volts constantly. I rewired the entire engine bay with all new wiring. I have a ground from the motor to the body, from the body to the battery, and a wire from...

I pulled the 383 out of my 67 D200 to freshen it up. I am planning on leaving the bottom end stock and putting new bearings and rings in it. The heads are the 516 castings. I plan on swapping the 2bbl intake for a 4bbl, maybe a cast iron intake. I am thinking of going with the xe268H cam...

Living in Minnesota my vehicles are parked for several months out of the year. I was wondering what kind of insurance coverage everyone has on their collector vehicles and what it covers during storage months? I need to get coverage on my duster and my 67 D200 but I want to make sure they are...

I have decided to rebuild my 340 for the 2nd time. It dropped a valve after the first rebuild.... don't ask.:banghead: The block is fine but the head is shot and so is the piston. I was wondering what everyone was running for pistons in their 340? I was considering Keith Black KB243 pistons...

After working on the 1967 Dodge D200 I bought recently I have to wonder what the engineers now days are thinking when they design vehicles. I had to remove the heater core on the 67 this weekend, remove 3 bolts from the firewall and the whole heater box comes out of the truck. How about...

Hey 4spdragtop the vin on that 340 is OB183694 and the casting number is 2780930-340-6 it was cast on 7/14/69.

Hello all. I have a 1969 340 and I was wondering what it is worth. All the machine work is done on the block. It is bored .030 over, crank is polished, block is zero decked and was cooked out. I built the motor but I made a rookie mistake and forgot to check valve to piston clearance. It...

I just bought a 1967 W200 camper special 2wd. It has a 383 with a 727 tranny in it now. It is all original with 46600 miles on it. I have a 1974 440 out of a motorhome that I was thinking of rebuilding to put in it. What would everyone else do? Rebuild the 383 and keep it numbers matching or...

I bought a 360 that was rebuilt about 5000 miles ago. I pulled the heads off to do some porting and a cam change and found 2 different casting numbers. One is 3418915-A and the other is 4343475-A. Are these heads the same as far as flow numbers? Are they the same cc? They both have 1.88 and 1.60...

I am looking at buying a Mallory electric fuel pump. Part #4070M model 70 30 gph, 180lbs/hr. Anyone ever run this pump or have any issues with any other Mallory pump?

Ok, I am sick of the annoying Holley fuelpump on my Duster. Anyone have any suggestions on a good gerotor fuelpump? How many gph freeflow should I have for a 400+hp 340?

I need to buy new rooof rail seals and window seals for my 74 Duster. Just wondering what company to order from? Anyone have bad luck with any certain brand? Thanks for your time and info.

Does anyone know of a company that makes a 1-1/2" fuel level gauge? I am customizing the dash in my 74 Duster and I can't seem to find one.
