What's the difference, if any, from the 1972 and earlier and the 1973 and later strut rods. I need one for my kid's '74 Duster. Want to make sure I get the right one if seller is unsure.

Thanks Chief, I'm not positive about the 167's, but with the open chamber 675 heads I probably wont hit over 8.5. I'm trying to get by with minimal machining to cut cost. The KB 399's might do it, but I'm not sure of chamber volume on the heads to determine approximate CR.

I have a '73 318 laying around that I want to build on the cheap for my kid's Duster. I want to run a Hughes Whiplash cam in it to give him that sound we all love. I will be using the stock 675 heads, Edelbrock Performer, Carter Comp AFB 625, Heddman headers, 904 w/ Trans Go kit and 3.21's...

Well the kid finally did it, he lost it and smacked the curb so hard he folded the front left wheel. While I'll be in possession of the Moose Mobile (74 Duster w/ 273 Commando) for a while fixing it, I thought of doing up a spare 1973 318 I have laying around. The 1965 273 Commando that's in the...

3forty's right. The "OLD" DC Hemi grind from the 70's was speced out like he said. It got superseded with the one MP has which is a straight 280/.480 configuration.

I want to buy a shift kit as a Christmas present for my son's 74 Duster. It has a slightly overstock Commando 273 with a 904 and 3.21 8.25 differential. What's the consensus of these two brands and what's the popular product to use/buy? Thanks. I need to order soon, so fast advice is appreciated.

I bought an NOS sure-grip differential on eBay for my kid's Duster. These are from a lot of old stock and loose and unboxed, therefore no part number. However,they are marked on the case with the number 18-05-039-903. Please tell me this is the correct size case for 3.21 and lower gear ratios...

Timing is set at 12 deg. static and totals around 36 deg. mechanical. Add about 12 more deg. for vacuum advance. I fished around for a short slot advance cam for the distributor specifically to run a lot of initial timing for low end. The kickdown is set for WOT and it opens all the way, however...

I like the gear idea. What about 302 heads? I've been reading the site since I posted the thread. I really don't feel like building another engine. If a head swap and gears will wake up this thing, that suits me fine. Oh, the cam specs are 270 deg. advertised, 224 @ .050 and .468 lift in and...

I have a FREE 318, and the Schumacher mounts I have are 273/318 only. the 340/360 one's are different. Trying to go cheap. Maybe advice on more power in the 273 would be better, since it's only got about 3000 on the rebuild.

The heads are original 64-65 castings, same as the block. The compression in the 273 is 10:1, putting out about 160 psi. I know that due to the tiny bore of the 273, that heads are a very limited choice due to clearance issues. Any other ideas perhaps?

Hey guys, it's advice time for me and my son, Moose. That 273 we did early this year is a slug. He wants more GO. so we're thinking of up sizing to a mid 70's 318 my buddy will give us. The 273 has a new Comp Cams 270 Magnum solid lifter cam, Eddy Performer 318, Hedman headers,in a 74 Duster...

Ok guys, I'm glad some of you know what I'm talking about. And for those of you who don't, here's the deal. Prior to 1971 Chrysler had no part throttle kick down on V8's. The sixes had it to help putt them along at lower street and cruising speeds. The linkage regulated pressure and kick down at...

Thanks Larry, You're right, I did a bracket change on the original pump from the car. I'll try that and see if it works, Thanks again. Ted

Just what I needed after 2 months of trying to get my kid's Duster on the road. I finally got the engine swap done and the P/S pump leaks like a stuck pig. It seems to be coming from the front section of the body, not the shaft or lines. My buddy thinks the res O ring is bad, but it didn't leak...

Hey guys, I finally got the Duster (273 & 904) on the road and I'd like to install part-throttle kickdown in the valve body to help it along. Can I simply pull the housing and plug off of a slant six tranny and slap it on? or is there some other tips I need to know? I haven't cracked open a...

Very nice close up photos. Thanks a bunch. I pretty much had it like that, but the alignment was off a bit, so I gave up wondering what was incorrect. I'll try again tonight.

I got the 273 all nestled in the '74 Duster and I need to hook up the Saginaw pump that was from the slant six that came in the Duster. I bought a complete bracket set for this application, but I dont know how this crazy bracket arangement works or where it attatches. There's a great pic on ebay...

I just went through a 273 for my kid's 74 Duster and I picked the Comp Cams 270S Magnum, P/N 20-264-4. The specs on this one is 270 advertised ( 224 @ .050 ) and .468 lift. It's a single pattern profile. We just got the car fired and I'm still working all the bugs out of this Slant Six swap, but...

Yes Steve, you are right on. When the dots face each other, my engine is at #6 TDC. Is that normal? I always assumed that dot to dot meant #1 TDC. Well this why one asks and learns I suppose. Thanks.

Am I a dumbass or don't I get it? Ok, here's the deal. I set my 273 at TDC and insert the new bump stick ( on engine stand ), I go to install the timing chain with the timing marks set to "dot to dot" per instructions and the cam is 180 degrees out of time according to the Mopar valve lash...

Ok, I wanted him to ask that, but he forgot to mention that it's the power steering brackets we're working with. We pulled the /6 and dropped in the 273, but the donor car had no P/S hooked up, so can the brackets from the existing Saginaw pump from the /6 be adapted to fit a small block or are...

Ok guys, I scrubbed the motor and tore off the heads. I'm not sure what factory domed pistons actually look like but these pistons are definitely aftermarket slugs. They're flat top with 4 valve notches in 'em and stamped 060 on the piston face. Any ideas? I may as well pull the cam and have it...

If I used timing tape and set the 90 degree mark at the zero line on the balancer, that should work too, I think.

Thank you, Tony. I really appreciate it. Ted

Ok, dumb question but I need to know. The 273 I have is missing the timing tab, so I considered replacing the timing cover to a post '69 type since I'm running the newer type water pump anyway. Will the existing balancer work as far as the timing mark lining up with the newer cover, or is the...

Wow, lot's of good info and advice here. This answers alot of questions I had requested in my post. For Mooser, I think freshening up the 273 would be the most cost effective and prudent thing to do for now. Hey, at least he'll have a V8 instead of a Slant Six. Before I get bombarded by all you...

I don't know the gear ratio yet. I tried doing the spin test on this peg leg, but still I couldn't get an accurate reading. I'm planning on 3.55's for the Moose Mobile. As far as the heads go, my buddy has a Performer he'll give me and machine the bolt holes to the early 273 configuration, and I...

Hi John, I need that same info, however I did come across a great info site that may help. Ted http://users.erols.com/dmapes/THIRD.HTM

Thanks for all the input guys! It does have the '65 273 heads on it and the block is dated Dec. 65. I know that Edelbrock is a low rpm intake, it's runners are real small. If I remember right, the SP-2P was a 70's 318 upgrade for mild street use and to gain 4 bbl power over stock 2 bbl and the...
