    Should I buy this 440?

    According to "Chrysler Engines: 1922-1998" by Willem Weertman, the E85-code police HP engines went through 1975 and had true duals, low-restriction air cleaner, and the Magnum/Super Commando camshaft. If the HP 440 was continued through 1978 like the Hemmings article says (seen it referenced as...

    Signs you're getting old for Classic Car Owners

    Lol I wear the gold toe low-cut socks, occasionally with slip-on sandals but not really outside the house. More around the house or garage if I'm not wrenching. I just don't like how white socks look especially if I'm wearing shorts, apparently high-cut white socks are "in" with the teenagers...

    Signs you're getting old for Classic Car Owners

    I have dreams every now and then where I'm banging gears in my old 5-speed '93 Cherokee, it was my daily driver for 10 years and then got rear-ended and totaled. Even in my dream I think "hey I thought I didn't have this car anymore...?" Lol. Then I wake up and remember it got crushed 3 years...

    A body twin scoop ram air

    Also the Challenger T/A scoop and later Duster/Dart Sport single twin-snorkel scoop. That's a big reason why I went with one "incorrectly" for my '70 Duster. MP Chassis manual has a section on it, pretty enlightening. Most muscle-era hood scoops are about looks more than anything, the engine...

    Mopar engine differences

    B and RB are both commonly referred to as "big blocks", it's a colloquial term. OEMs never really officially used the terms "small" or "big" block. I've seen 2G Hemi referred to as the "big block Hemi" which it basically is, 426 RB with Hemi heads.

    Buying a car without keys

    That's what I did for my Duster after some dipshit thief destroyed the ignition lock cylinder trying to steal the car in 2013. Luckily the car was a 70 so locking steering column, I also was doing some engine work so no way he was going to start it anyway. I think I got a kit off ebag with new...

    Junk lifters

    He says in one of his videos that he's Rockwell tested a ton of lifters (and cams) and they all checked out good, it's not a metallurgy issue.

    People building cars should watch this.

    If you thrash your Mopar at road courses and autocross events (like Chris Birdsong does) with lots of hard cornering the Green bearings (ball bearings) can't hold up to the sustained high thrust loads. The vast majority of classic Mopar owners don't do that though so for most people they're...

    Best Brake related company for parts

    I had that problem with my OEM MC, realized it was coming from the cap so I bent the retainer more to hold the cap on tighter and it no longer leaks.

    Interesting video on early turbos, "hemi honker," "turbo honker"

    I think an issue of Hot Rod magazine from 5-10 years ago mentioned this but super cool to see a full video on it. 40+ psi and 140mm turbos, insane! Nowadays we know just one of those would be plenty for a 426 Hemi but they were treading new ground back then. Definitely looks like something...

    Break in cam with new Schumacher ceramic headers?

    This ^^ If they won't hold up to the engine being run at 2000-3000 RPM for 20-30 minutes then they won't hold up to cruising down the road at a steady speed. Unless maybe the short block is also fresh and hasn't been run at all yet. Basically all you need to do is make sure the headers don't...

    Sad day, but I had to put the car away.

    It hardly gets to freezing temps here so no winter storage. I was living in the same place as @Dana67Dart before I moved to GA earlier this year and did the same as him, drove it in the snow as long as there wasn't Mag Chloride (salt) on the roads. Since it's humid here and my '72 D200 gets...

    Power Wagon ( Heater core )

    Good idea on keeping the old one, can't trust anything aftermarket these days tragically. The shop that fixed mine at least did a great job on it so it was worth the cost in my mind. Their main business is repairing radiators, intercoolers, heat exchangers etc on big rigs and construction...

    Power Wagon ( Heater core )

    My D200 is the same generation truck but it came with factory A/C which uses a different heater core. Mine sprung a leak and no replacements were to be found, I think to have it recored at a shop in Denver which was the only place within 200 miles that did it was at least $300 and that was back...

    Am I just SOL?

    Now that used Mopar parts sellers have caught on to the idea of cutting down B- and C-body and truck 8-3/4" rears to A-body size there may be less of a need to use Ford units. I'm still not opposed to them but I do agree the Powr-Lok is a better LSD than the Trak-Lok.

    Honestly...how good was the 318...mpg / durability / hp

    I had a 1988 Chrysler Fifth Avenue, roller-cam 318 that was bone stock when I got it and very well maintained. I got rid of the Spark Control computer and converted to conventional electronic distributor and an old MSD box I got for free from a friend. Put on a Performer intake and Thermoquad...

    Am I just SOL?

    That unsprung weight is literally at the roll center of the car so the effect on handling is negligible. If that's really the concern get some aluminum 17-18" wheels and 35-40 series tires, way more bang for the buck in reducing unsprung weight in a useful way. Also it'll be a massive...

    Honestly...how good was the 318...mpg / durability / hp

    The original 318 that was in my '70 Duster was poorly maintained over its 115k mile existence before I got the car in 2007 but still ran smooth. Nylon teeth on the cam sprocket all sheared off (as in, every single one) and the valves kissed the pistons when I was pulling out of my high school...

    Just purchased ‘98 Jeep Grand Cherokee 5.9L

    I LOVE ZJs, reminds me of my beloved '93 XJ Cherokee. 4.0 straight-6, 5-speed manual, part-time 4x4. Bought it in 2010 with 180k miles and it was a cream puff, my guess a former gov't fleet vehicle as it had ZERO options besides the driveline setup; manual windows, manual door locks, no A/C...

    supercharged "HEMI" six cylinder

    At least the new Hemis are cross-flow with huge valves so they have the breathing ability. They got away with calling the Aussie 6 a "Hemi" because the rockers were mounted on studs like a Chevy and were ever-so-slightly canted toward each other. Still reverse-flow like any old-school inline-6...

    Duster-Tazmanian Devil Logo

    But they called a version of the Dart "Swinger"... hmm... EDIT: Spoke too soon I didn't know there was another definition lol (talking about the first one in the pic, I thought it was only the second one)

    Just a real quick question

    The original 318 in my 1970 Duster had one. That was the reason I had to pull the engine the first time, every single tooth had sheared off the cam sprocket and they were all in the oil pan and pickup. Valves hit the pistons so I put reman'd heads on it but should've just found another engine...

    Frame swaps

    Your Dart is unibody like all 60s-70s Mopars. It isn't body-on-frame like GM and Ford cars. Can't really "frame swap", more like cut out the entire floor pan of the car and graft the body onto something else.

    Methanol /Water injection

    Oh they can be built up to be nasty quick for sure but you'll be doing it with pretty much entirely aftermarket parts. Should've asked him how much it cost lol. That Mitsu engine was iron block with beefy crank and rods from factory and the Evo had AWD like the Soobs, big rivalry between the...

    Methanol /Water injection

    OP didn't specify but it may have allowed the Subie guy to safely bump up his boost to gain that 60 hp. Those engines are made of glass after all, they don't handle much boost over stock without blowing head gaskets and breaking ring lands. SuBiE lIFe brUH!

    Methanol /Water injection

    Do you currently need to run less ignition advance than optimal to avoid pinging? If not then water/meth injection won't do a whole lot. You would want it to be configured to activate based on engine vacuum/load too, not so much RPM. Engine Masters show on Motor Trend did a test with...

    More 3.6 carnage

    Hmm, maybe I'll look at doing a decarbon treatment on my mom's 300C with the 3.6 when I visit. Of course the oil would then need to be changed. Idk if the carbon buildup is really that bad on hers though, I was always good about changing the oil on time and when it gets driven it's usually far...
