Wtf i had a 74 dart/ slant, 3 on the tree and it was not a turd. It was no 36 mpg wonder either. But it pulled like a good little workhorse down the highway with light throttle. Your being too critical. The slant has such good low rpm torque i could literally let out the clutch with my foot off the gas and it would pull the car from a dead stop off dead idle by itself and creep untill i stabbed the gas. No other machine i ever drove would do that except a f250 with a 300 six and a granny low np 435 trans and 4.11 rear. The slant has incredible low rpm tractability and cruises hiways with ease .

Its got a fine steel crank. A slant is not a piece of junk. Now a chevy six is a different story. Plenty of snapped iron chevy sixes, especially the 292. Check out the turbo slant sixes on the internet living with plenty of boost. The lower end is okee dokee, with a long stroke and minimum main caps. Chrysler has a habit of making things plenty stout. But anyways , not that i wanted to debate the merits of mopars slant. I just dont see it as junk, i love sixes in general. I dont like gm’s stovebolt cuz it is the biggest loser in the six banger catagory, i think amc has a good one, but it could be better if they overbuilt it more. Its great for cheap cast iron no doubt. A steel crank and rods would be nice but obviously overkill. These are just passenger car engines. Its all just me yakking. I got a true junk 4.0, pulled out cuz of overheating, with a blown headgasket and stuck rings and overheated pistons, and i patched it up, and it might be dumb but i’m gonna see if its a turd and dies, or lives to laugh it off. No biggy i got a spare and its pretty easy to change out. Popular opinion suggest the 4.0 is a survivor. Lets see if a badly injured one can live on.

I went to summit today, i bought a jba 1526sy performance midpipe for a jeep, then i went around back to the discount outlet to see what kind of bargain junk they had. Wow they had a ton of neat crap to waste cash on! I got a msd three step launch control for 100 $, a powermaster 100 amp delco one wire alternator for 65$, a set of 16 mopar amc hydraulic lifters for 85$, and a gale banks stainless steel tri-y header for a 4.0 for 299$ . The header retailed for 569$. The one thing i found i could really use was a new innovate motorsports wideband air fuel ratio for 110 $. Yeah i probably dont need that header now but it looks cool as hell. Anyways the plan was get the jba midpipe and cut it up to fit my javelin, so i cut it up in a couple places and reconfigured it to fit . It wasnt exactly cheap at 289$ but it had all i needed in mandrel bends and it even had an o2 bung, and it made a nice 2.25 inch exhaust pipe. I probably should have got a muffler because unfortunately i discoverd the one i had was 2.5 inch and needs a reducer segment to work. Another great thing about a six is exhaust system assembly is easy! Half the work, half the weight, half the trouble.

Some good deals there. I have the Innovate f/a on the 70 AMX and like it. I'll probably buy another one for the 74.

It is a great addition to the dash, and it tells you a lot about your tune, how the weather and temperature affect it, its a fantastic tuning aide for any carbureted car. And it gives you a precise numerical value, which is much more informativr than some other af gauges that have colors or voltages.

Well heres some fun news, in line with the roadkill theme, and the constant process of learning and unlearning and relearning. My 26 year old weber carb. Well it sucks. I put a chicom kit in it. At least it ran and didnt flood. It drove like shit and ran rich. Hell its kinda been like that for years but somehow its worse now. What to do. Hey lets buy a new one! Right on! Poof I got a new “weber”…I thought…Nope. Made in china. It sucked perfectly. Even worse than my old genuine weber. It had more flat spots than my skull. Roadkilled. What to do. This is stupid. I took the old weber apart again. I thought gee, why didnt the chicom kit come with one of theses strange bowl vent diaphram thingys? Lets look at that. Hey spud, thats not a bowl vent thingy. Thats a fucking powervalve thingy. Lets check it out. 26 year old rubber dust. The powervalve was dumping fuel continuosly. Hence the richness and poor running. What to do. Order a genuine weber carb kit with a power valve. Omg its 97 bux. Send back the brand new junk chinese fake weber abortion. Rebuild the old carb again. Do it right this time. Fix that unimportant “ bowl vent”🤣 how funny🤬

And so, the 4.0… like they say on roadkill… “ is pretty good”. It toodles around kinda like the 232, but has more horsepower! It drives well and the five speed is sporty and fun. It wont outrun my 304 javelin but i never really expected it too. I think by fall it will be good for some real roadtrips. Theres tons of little things to do yet before its a reliable road machine. Stickshifter’s stroker 4.7 for his eagle already has me pretty curious about more power for roadkill. I need a block bored for a 4.7 motor. Life is short.

You sure do. How is the supply of 4.0 junk up there? I know your busier than a one armed wallpaper hanger😆. You game for some amc sicks banger work? I have all the guts to build a 4.7… just need some farm guy technologies sprinkled on it.

Stickshifter probably has a source or look on Craigslist. I will shop locally for you. Right now it is full bore on my SC360 until done. I can get the machining done for you but you will have to assemble it yourself or, wait a while.

Not in a rush. I probably got as much arthritis as the next reb’s reject. Just another good excuse to visit.

Roadkill got a new fan, thermostatic fan control, dash mounted fan overide switch, i kept the old thermal switch as a failsafe. One of my old fans crapped out. It worked some of the time but was weak compared to the other fan. ( The old reoccuring problem of using recycled parts i guess.) I had a thermal switch and a relay rigged up, but the only place i could put the thermal switch was in the water passage in the intake manifold, and the fan came on kinda late and at different coolant temps…so i decided i needed more sophisticated fan control. I bought a davies craig adjustable control, with dual relays for the dual fans. It has switch that will fit in my thermostat housing for a more accurate coolant temp.. Maybe this will work better than the old rig. Also, a New line lock was installed in the brake system. ( it works). Adding to the interesting control array next to the master cylinder. The twin grip is not my freind. Its tight and is a hassle with cornering and the manual steering. The 3.15 gear might be a shade to strong for cruising with the six banger. However it might be great with a stroker 4.0…Not sure but a 3.31 gear might be better, and i could run taller tires…or tune it in with taller tires. Right not i got 14 inch rims with short 24 inch bfg’s. So i cant go with shorter tires to help the 3.15’s… Kind of uncertain how to go about it, i think i might be putting together another axle assembly with a 3.31 gear and maybe… an ARB air locker. For the ultimate in dual porpose tractability. Not sure i really wanna do that, but i want an open diff for drivability in all weather and a easier steering and less tense handing over the twin grip posi. Really i hardly ever need a locked rear axle. The ARB seems like a better alternative. So more tweeks ahead, to get the all important sweet spot on the overdrive gear/ rpm mpg nirvana.

I welded in the structure that goes across the top front of the radiator, it has the rubber stops for the hood on it, and is what the hood latch bracket bolts to. Whatever you call that was cut out by a previous owner. It was causing the inner fender structure to bow inward. So anyways i had to push the inner fender structure back out, and carefully fit another piece in there and restore all that to pre butchered condition. Also the lower structure that goes in front of the bottom of the radiator was ruined, maybe someone pulled it up on a trailer or tied a rope to it or something. It was all yanked out of position and i thought i could remove it and straighten it. I also needed to make some more room for the botton of the radiator, and that old structure was in the way of the new rad… So i drilled out all the spotwelds on it and removed it, and drilled out more spotwelds and dis assembled it, and hammered the pieces into shape, and they developed holes as the rust scale fell out, and developed some cracks from the stress of bendin out of shape and hamering back into shape. I welded and ground and hammered and dollied for a couple days. Then i tried to fit it back, ultimately i had some better looking shit that was a ton of work and needed a ton more. For what? This shit is flimsy as hell and what is it good for except getting bent all to hell? So i looked around for something better. I didnt have any reall good square tubing or structural steel. I looked at work, and went to the scrapyard. I didnt find anything that looked usefull. So i forgot about it for awhile. Then i stumbled across some 1.5 inch tube pieces, they were left over from my 304 header project. I pieced together a tube from them and welded it in. It came out pretty decent, and is a lot more structural than that flimsy shit that amc used. I put the hood latch structure in and tweeked it to the right posistion fot the grill support and grill to fit right, welded up this heinous hole some fool burned into the radiator support with a cutting torch, and buffed and scuffed it up for some black chassis paint. Bunch of work but it paid off in a lot of awesomeness. I got a real hood latch and dont need a bungee cord anymore, i adjusted the fenders and now my hood fits between them, i got hood stop rubbers now, my radiator isnt rubbing on tweeked and bent body structure. This car has been quite a bit of work but i guess hindsight everything is. It looks like a joe dirt javelin and it is getting there.

Well the new powermaster alternator that i got from the summit junk table didnt work. Yay. Because roadkill. The old reliable 50 year old delco is back on and working. I think something is weird with the new msd distributer. I have developed random misfires with the vacuum advance hooked up. It runs ok with it disconnected. Maybe when the mag pickup rotates, it misfires? A glitch in the wires? I dunno. Too many problems from the new junk. Not so much from the old junk.
