    90 degree oil filter adapter or not?

    I have a 360 that is going into a 1970 Duster with Hooker Competition headers. The Oil filter clears the header as shown in the picture. I plan to go with a shorter filter than the one in the picture. Do I by some other reason need to use a 90 degree oil filter adapter? I would rather not use it...

    360 timing cover, which bolts go into water?

    I cant seem to find it here on FABO or by googling. I did find info on the water pump bolts. But are there any of the lower timing cover bolts that go into water or oil and need to be sealed?

    Engine balance after new pistons

    After talking to some friends I'm a bit confused about what I need to do to get my engine balanced and correct. I am putting together a 360. My plan is to use the stock crank, rods and damper. The flexplate I will be using is the B&M Flexplates 10236. I have bought Speed Pro Hypereutectic...

    DIY cam bearing install

    Putting together my 360 I would like to do as much as possible myself. Why? I would learn from it and also maybe get some satisfaction out from knowing that I did it myself. I have never installed cam bearings, but I think I could do it. Most of my friends have had the shop do this for them. No...

    Cam choice for low comp 360?

    I have been reading a lot, and doing a lot of searching on this forum. But I still am not able to fully grasp the science behind this So I thought it be best to ask. I followed 19 questions on Hughes website so I could provide you with the right info for helping me pick a cam. Car - 1970...

    Finally, my first 360 and goals for it! I'll be asking a lot of questions.

    I'm picking up a complete 360 this weekend. It runs great and everything is there except the carb. I won't know what cam is in it before I have it apart. It's a hydraulic though. The heads are the 3769974 casting and it comes with a LD340 intake. I have a 1970 Duster. It was a /6 car when I...

    273 and 360 interchangeability?

    Well, it looks like I might finally get my hands on a 360 over here in Sweden. I have a really nice running 273 (1965) commando in my Duster today. The 360 is a rebuilt long block. Will my 273 timing chain cover and waterpump fit the 360? I'm spending pretty much all I have right now on the long...

    Match intake to heads?

    I have the intake off and as you might or might not see in the picture there has been some porting done to my heads by a previous owner. I have the D4B intake. Would it be a good idea to port it to match the heads or should I leave it as it is? I have time to do it, but I never done it before...

    Two port breather - Alternatives?

    1970 Plymouth Duster. Originally /6 but now have a 273. This breather came of my slant 6. The small hose, is that for gas tank ventilation? I was thinking of blasting and painting my valve covers with black wrinkle paint and I thought it would look nice with a chrome breather (i have the pcv...

    Leak: fuel pooling on the intake manifold

    Take a look at the picture. After a good day of driving today I found fuel where the arrows are pointing (I had wiped most of it away before taking the picture). While idling I could also see some, what I believe is fuel, bubbling/sizzling between the intake and head (closest to the area of the...

    Lost power all of a sudden. 273 commando.

    So let me explain. One week ago my car ran really really good. I have a souped up 273 commando. I'll give you the specs at the end of this. It still runs very good when I cruise around. No bogs, no nothing. But, when I stomp it it's like I have lost 30% of its power. It will hardly spin the...

    Can you see if there has been any work done to my heads?

    Hello! I'm home with the flue, bored to death. Can you see by these pictures if there been any porting done to my 1965, 273 heads? I myself have never been deeper into the engine then when I did this cam swap without removing the heads. Remember thinking it looked like someone took a grinder to...

    Driveway Cam Swap 273 Commando, pics and video

    With help from this forum I prepared to swap out the hydraulic cam the previous owner had put in my 1965 273 commando. I thought I might share some photos from installing and a video from breaking it in. I wanted to go back to mechanical and put something wilder in there at the same time. This...

    A modern mechanical cam and springs requires what work on the heads?

    Have a 1965, 273 commando. Previous owner swapped the mechanical cam, lifters and rockers to hydralic and put a 340 cam in it. He did not change the springs, though. I'm plying with the thought of swapping it back to mechanical since my friend have mechanical rockers, rockershafts and pushrods...

    273, could it be a commando and CAM question?

    I have a couple of questions but first a little info. My 70 Duster was originally a /6 car but I have swapped out the slant for a 273. The motor runs great and seems really healthy so I have not really done anything to it besides plugs, oil changes, filters and tuning. Instead I have made...

    Struggles after 4900 rpm

    My Duster usually shifts from first to second gear at around 5500 rpm, and chirp the tires. Now it shifts at around 4900-5100 and wont chirp the tires. It feels like it it struggles when it reaches 4900 rpm and don't want to rev more. There is no pinging or destructive sounds, it just feels...

    Need help tuning a 273.

    This winter i switched out the slant 6 to a 273 in my Duster. The 273 was previously owned by a friend of mine and ran really good in his Dart, strong and quick little engine. I haven’t really done anything to the engine besides cleaning and panting it, changed filters, oil etc. I had to...

    Starter problem.

    The starter worked fine earlier today. I was tuning the engine and stopped and started a couple of times when it gave in. First it would sound like it would not engage fully and make that rattling noise against the cogs, then it only clicked. I turned the engine by hand and tried again, the...
