Hey everyone, I have not been here in FABO for a long time. Anyway I purchased and installed a new MSD 6AL 2 programmable box in my Duster. I'm having a problem with writing programs with the MSD software that came with the new box. The software loaded into my laptop, no problem and its easy to...

I'm driving my 440 Duster there and hoping to get it into the 10s. Hopefully I'll see plenty of Mopars there! Zmax rarely runs events like this.

I'm selling two bare cylinder blocks. One is a 400, casting date is 2-16-72, casting number is 36142304. The other block is a 440, casting date appears to be...

OK, I know its probably been discussed but I did a search and could not find the info. Anyway with that said I'd like to know if all 340 blocks are the same or if there's a particular casting number or year that's better or is there any years to avoid. I'm planning a small block build and I'm...

I've been trying to link YouTube videos and can't do it. Can anyone explain how to do it? Thanks in advance!

Its time to swap out the roller lifters in my 440. I have COMP lifters in it now and they have over two years on them now. The car gets driven about 1000 street miles a year and has about 30 drag passes on it so I don't want to push my luck. I don't want to use another set of COMP lifters so I'm...

I'm looking for two Weld Draglite wheels (also know as 90 series) 15x8 with 4.5 B.S. and 4.5 bolt circle. They don't have to be in perfect condition, some patina minor pitting or minor scratches are fine as long as they are not bent or have any other serious damage. Thanks in advance.

Just checking something. I have two people telling me their A bodies came out of the factory with 9 1/4 axles in them. I've never heard of or seen this. Does anyone know about this? Did Mopar ever equip A bodies with this axle?

I know its well known that the little Scumacher headers cost power, but I have not seen too many actual tests so I'm posting my results to give some insight. My car is a 70 Gold Duster street strip car. It weighs exactly 3500# with me in it and a full fuel cell. The engine is an 11.5 to 1, stock...

I have a 440 with about 11.5 to 1 compression. The cranking pressure is 210 psi. I've been running it for over a year with Champion RC12YC plugs with no problems at all. I run 93 pump gas with Klotz KL628 octane booster and I'm not getting any pinging or dieseling when I shut it off and have not...

I have a 70 duster with a 440. Running Wilwood discs front and rear with a Wilwood 7/8" bore MC. I'm now installing Proparts headers and the Wilwwod MC is much too large to clear them. I'm thinking about going to an original non power/four wheel drum style MC but don't know the bore size. Does...

I'm considering building a 360. I don't want a stroker, I want to stick with a stock 360 block and crank. All I want to know is what are the power and RPM limits of the stock 360 block and crank, both LA and Magnum.

I have a 440/A-518 in my Duster. My trans rebuilder was unable to get a manual valvebody for it. I have searched in vain also. Does anyone know where I can get one? I'm looking for a reputable source not a shade tree rebuilder.

Now that I've jumped into the pool and learned a little about the world of Mopar performance, I'm in the very early planning stages of the next motor for my Duster. I am sticking by my chiselled in stone rules and two of the biggest ones is the car keeps a flat hood an air cleaner and no power...

I keep seeing people on the internet giving advice about building big block A bodies. One thing I see a lot is people saying you have to swap out the six cylinder torsion bars if you're swapping the big block for a slant six. I just want to let anyone doing the swap to know that it's not...

I have a complete Wilwwod brake system on my Duster. It's a Wilwood tandem master cylinder with wildwood discs with Wilwood four piston calipers on all four corners. I had a lot of issues with faulty brake line flairing when doing the install, and wet through quite a bit of Wilwood 570 brake...

I'm driving my 1970 440 Gold Duster up to Lebanon Valley on Wed Sep 3rd to race. If anyone else is going let me know. I took th car up in July and the best time was 11.68@114. I trailered it up and a buddy called it a trailer queen. It's a street car so I'm going to make him eat his words. To...

Well it was a long time coming but I finally got my 70 440 Gold Duster up and running and to Lebanon Valley. It's a street car, registered and insured with full exhaust, interior, power steering and all. It has a flat hood, runs on 93 octane pump gas, and is fully streetable. I made 7 passes and...

I need a RF (passenger side) fender for my 70 Duster. I did a quick internet search and it looks like they're not available new. I checked ebay and they are available used. I have two questions. 1) Does anyone know if they can be bought new? 2)If I have to buy a used one, what years are...

I finally got my 440 running. It's a street strip motor with about 11 to 1 comp. solid roller, 440 Source Stealth heads and a single plane intake. It seems to run well but I was only able to drive it very little because the transmission has an issue. My concern is the oil pressure. IDK what the...

Well its taken a long time but I'm finally getting close to getting my 440 Duster running. I have not tuned or raced any cars since the 90s and I have never even driven a big block Mopar, let alone tune one, so I'm hoping to get some input on where to start off. The engine is a .030 over stock...

I'm finally getting ready to purchase a one wire alternator. Powermaster has Mopar units that are converted to one wire units with a built in regulator. They have 100 and also 60 amp units. I'm tempted to go with the 100 amp one mainly to quicken up the battery charging at the track and also to...

I'm using Stealth heads on my 440. It has Speed pro flat tops and the block has been decked for a zero deck height. I want to mill the heads but do not want to cut them to the point where milling the intake becomes necessary. Can anyone tell me how to determine how much I can safely mill them?

I'm building a 440 Duster. Its a street strip car and the battery has been relocated to the trunk. I'm redoing the under hood wiring harness also and would like to clean things up. I'm looking at possibly buying a Tuff Stuff one wire 100 amp alternator from Summit and losing the factory voltage...

I'm setting up the valvetrain on my 440 and I have Crane alum. rockers. I don't have any instructions or diagrams. The Crane setup uses springs on the shafts to hold the rockers against the shaft hold down clamps. There are 8 thin steel thrust washers for each shaft and what I dont know is; Do...

What oil pump would you recommend for my engine. Its a 440 with stock stroke steel crank, Eagle rods, speed pro forged flat tops, a Milodon 7" pan that looks like it holds about 7 quarts. I'm using CNC Stealth heads, a Comp extreme energy 292 solid roller which Comp says works good from 3500 to...

I'm building a big block Duster. I removed the original slant 6/904 from the car. No one wanted the engine so I scrapped it. My question is; Is the 904 from the slant 6 a suitable core for a full race trans to go behind a big block? I know that no 904s will bolt to the big block without a...

I'm going to use an A-518 behind a 440 in my Duster. I know I have to modify the floorpan and fab a trans crossmember. My question is with bolting the small block trans to the big block. The only adapter kit I've seen so far is from SMR trans and its over 500 bucks which is too expensive as far...

I'm putting a 440/727 into a 70 Duster. The car has the original slant six K frame and I'm usung Schumacher mounts and headers. I have two 727 transmissions. One is from a 74 Imperial 440 and the other is from a 72 Newport 400. My questions are; Is either of these trans cores better than the...

I'm new to Mopars so I have lots to learn. I have a 70 Gold Duster. I'm not moving the springs inboard. I want to know what are the largest tires that will fit into the stock wheelwells without any mods or sicking out at all. I'd like to go with 275-60-15 drag radials. Also would like to fit...
