This old bruiser has a lot of sentimental value. It's a 1973 AMC Jeepster Commando with a 304V8, TH400 trans, Dana 20 front, Dana 34 rear, and Dana 20 Transfer case. My old man bought this thing in 1985 and it served us well as a family vehicle and weekend dune climber. It was originally pumpkin orange with a hard top(still removable). As we moved on in years and cars, he always kept it around. By the time I was in high school in the mid 90's it had mostly been relegated to yard mule duty. Rusted to hell and back, beat to hell and back, just pitiful. Dad, being a residential contractor, was making beaukoup money from the late 90's all the way up to 2008 and had all the body work done and painted DuPont hunter green with some blue pearl-coat. 2008 happened and it slipped back into disrepair. I talked him into selling it to me( supposed to be inheritance but poo poo happens ) and got it hauled down here last weekend. Upon arrival it had jumped time and was worn the hell out on several fronts.  I dug into it almost immediately found some pretty gnarly stuff  In addition to the timing bits, the dist gear was ate to hell and back. The dist gear also drives the oil pump on an AMC 304. Once I got the chain and cam gear done, I dropped in a Summit HEI, ran a new fuel line and added an electric fuel pump. She fired right up. https://www.youtube.com/watch?v=_Js1E1VB5EM There may have been bourbon involved in the recording of that video. The list as it currently stands: Replace timing chain and cam gear - Done Re-time and upgrade to HEI - Done New fuel line and electric pump - Done Replace Brake booster and MC - Done Adjust vacuum advance - Done Replace rockers - done Replace Cam - done Replace lifters - done Replace Pushrods - Done Fabricate and install transmission lines(dad literally put rubber hose over the leaky parts and zip tied them)  *possibly* replace tires - They're oh so slightly dry rotted but it wasn't stored outdoors and they hold air, might be ok. repair/replace steering column sensor switch(to keep it from turning over in reverse) Replace every bushing I can get my grubby little hands on. Replace Pittman Arm Replace Tie Rod ends Replace Power steering cylinder Farking Bastage fucked around with this message at 02:24 on Mar 11, 2016 |

That HEI is a blueprinted application from summit racing made for AMC v8. Had an internal module and the oil pump slot,literally a drop in replacement. I haven't done a leak down test but the complete absence of blue smoke and good oil pressure would seem to indicate the engine still has life. If it goes I'll get it built. Lifters are noisy and have been since about 1990. There was minimal oil on the plugs after sitting 2 years so that's probably valve guides. I have a 600 Webber 4bbl sitting on a shelf that would be a good application for it but the intake for that engine is like 300 bucks. That transmission will probably out live me.

I got the proper Brake booster/MC/Spacer combo installed, bled out all 4 wheels and it stops like it did in the 80's. Dad trusted some Autozone dick to source him the right part and the brake pedal has been like kicking a cinder block for at least 15 years. The first cue that I had the right part was the fact is was 1.5X the size of the old one. Astonishing Wang: As soon as it is finished uploading, i'll post a walkthrough. <3

I think a carb rebuild is in order sooner rather than later. Having some issues under load. The timing is pegged on 5 deg BTDC ( the factory spec) and even with the Vacuum advance plugged, it bogs down under load and backfires through the carb. Does that sound like not enough fuel to you guys as well?

I'm done with that tired rear end ford carb. Timings dead on and after a rebuild the accelerator pump is still fail. Got a 600 Webber 4BBL sitting here off a 4.3. Manifold, throttle adapter gaskets for manifold and coolant neck here Monday.

I got it in a trade for a lovely pellet gun. Came off a marine 4.3. Coworker was eager to get rid of it. Has the fuel regulator and all. The main difference between the two is the electric choke, which I will wire off the solenoid on start.

I got it out by hammering a 13mm 6 point onto it. Once inside, I figured out pretty fast why is sounds like a skeleton jacking off in a wash pan full of metal spoons. Rockers are loose as gently caress. These engines use little aluminum pivots and they wear. Several pushrods were plugged which explains the wear. May as well do the lifters while I am an there. I really don't want to have to pull the Camshaft. I've had people tell me rather emphatically that you can use a zinc based break in lube on new listers and they will wear to the cam just fine. Thoughts?

I suffered a bit of a setback attributed to alcohol, black RTV, and a torn intake gasket. Regrouped this week's evenings and got the valve covers back on and took some time( like i loving should have to begin with ) to mock up the intake and see where stuff interacts.  I figure that electric blue engine paint on the VC's will match the equally electric blue plugwires

I can't get that intake to line up  After some research i've found out that the recommended gasket from Edelbrock is wrong, so I went back to the original valley pan and that won't mate up either. Ordered a new valley pan and bolts after galling a few of them.

^^ You're right about the RTV. Problem here is something on the mating surface of the heads( hopefully the old valley pan) wasn't letting it sit down far enough to line the bolts up.

Mother fucker is on there. If you have been reading, I sourced that carb from a 4.3 marine application( basically free but in great condition and beats the poo poo out of $450). Stamped Weber 8867 which is an Edelbrock 1403 600 CFM 4BBL. . It has front and rear PCV openings, which is fine, but I need a timed vacuum port for the Advance on the distributor for an AMC V8. The automotive ones have nipples installed to holes on each side of those adjustment screws. From what I can see this one has the ports, but they are plugged, so I'm going to get the little caps out, press a fitting in and see if it works.  This one has an electric choke as opposed to the original Heat actuated choke, so I should be able to use the switched electrical lead running the HEI and the fuel pump to run it. There's still a million things that can go wrong with this stunt, but I'm feeling a hell of a lot better now.

I got that 4BBL adjusted out( the last video was with a massive vacuum leak) and it's kind of sweet https://www.youtube.com/watch?v=X6Jx2DSLjEQ The last time I put a vacuum gauge on it with old carb and valve train, it fluttered 5-10" It's Dead rear end on now.

I took it out today!!!!!!!!!! The engine performs like I had hoped. A light throttle tap spins both back wheels on dirt, a generous nudge on pavement makes tire smoke. All the power is way down low. Decent higher up but it is a low end grunter for sure. Quite the opposite from my DD which is a 4cyl turbo. Now for the bad news. She runs and she cools, but she doesn't charge. I took it to the gas station about 5 miles away to fill up and I thought I saw the slightest flicker of an AMP light. By the time I got home it on fully on. Being that I replaced all the spark, choke, and fuel delivery with electric versions, that's not good. Going to pull the alternator and have it tested. Normally, I would just order one since they're dirt cheap but, I can't find data on what that AMC V8 alternator puts out and I'm concerned that the electric choke could be drawing too much.

SNiPER_Magnum posted:I didn't see it in any of your pictures, but it's mostly likely a standard Remy 10SI alternator. They usually put out ~40 amps in base trim, and ~60 amps if you are optioned out with stuff like A/C and defrosters. I'm guessing you are on the low end if it was never upgraded. I looked it up and it's 35-ish. Between HEI, Mr Gasket Fuel pump, and Electric choke, probably not enough, or just hosed for that matter. Going to pull it and at least have it tested.

Something I'm curious about. I think the secondaries on that carb are putting in a bit too much fuel. Everything ive googled says the secondary is manual. The primary is spot on but if you really step into it it seems like it's just bogging some and drowning in fuel. Is this the part where you change the springs out to lean it up some? It's an Edelbrock 1405
