Yeah - hope he hooks up those hoses to the filter or it's gonna get really messy really fast.
Extra capacity pan, remote filter setup, ready to rock n roll.
 
I've often wondered if it would be worth the $65 to get my car on the chassis dyno.
Not expecting great things, but for that money, you get a baseline, and I think they said "3 passes" simulating a quarter mile run. Could also figure out just HOW too rich the thing is at the same time.
 
Let us know how this turns out - photos of the actual run or a short clip would be fun.

I was talking about the thick billet peice at the bottom of the pump. An extention of the pump cavity for longer gears?

That's the remote oil filter setup with two AN fittings for lines to the remote filter gizmo.  One fitting is for the out flow line and the other is for an inflow line.  It allows you to place the oil filter off the hot engine and install an oil cooler if you want one in addition to the remote oil filter adapter plate.  I also got one from Bulltear but opted not to use it.  It can also accomodate an external oil line from the oil pan if I recall correctly.

Yes - thus my comment on remote filter setup. Like he said above..........

Bill,
 
For $65 it would be worth it. Just bring some stuff for your carb, some distributor weights and springs and tweak it. You will probably end up with a noticeable difference.

Something to keep in mid re: dyno's- I was going to run my X on a local dyno in the fall, but there was 1 problem ...it was not a treadmill style, it was the type that bolts right to the rear hubs, and the AMX axle/hub assembly was too deep for the adapters the dyno place had. Basically, the axle shaft and nut sticks out too far from the face of the drum. Something to ask about before you drive all the way to the dyno guy.

Rollers in the floor and the car is anchored to the floor. I've seen it as I drove back to their machine shop in the rear. They had a 57 Chebbie on it a couple weeks back.

Thanks for all the comments, I do realize that the engine dyno gives a particular set of results, and that the numbers will not be directly comparable to a chassis dyno results, or to AMC's factory ratings, be they SAE gross or net, etc. In the fullness of time, I plan to exercise this engine in the car on a chassis dyno, and to run it down the dragstrip a few times, then I'll have some % loss factors. It should be an informative journey, and I'll share what I learn. I have future plans to build an even hotter motor for a pure trackday Jav-AMX, hopefully we can all continue to share information to our mutual benefit. I learned a lot in researching the plan and parts for this motor, and a good percentage of that info came from this forum.

Check my post below for today's update on the dyno runs.

Today's update is that we solved various minor problems caused by 1) wrong parts and chasing replacements, 2) the need to fabricate something to generate belt tension on the two-pulley dyno setup, and 3) clearing initial flooding due to a stuck float. We got the engine running in the afternoon, and it has been broken in a bit, but the power pulls will have to wait until Friday or Saturday when I can get back over to watch. We also have a couple of minor oil leaks to chase, typical stuff for an initial startup. I attached some pictures of the setup from today, hopefully the oiling setup should be a lot clearer to folks from looking at the pictures. There is a restrictor in the drivers side oil galley, the plate at the bottom of the oil pump is the Bulltear 534 plate as others have noted, and the pump output is fed into the side of the block after going through the external filters (and a cooler when it gets into the car). Notice also that we have beaten Mr Bubblefender to market on a serpintine belt system, but it won't work if you need an alternator or power steering!!Wink (Look carefully between the pulleys on the passenger side).

I must say the engine sounds "the business", to borrow a British expression. Being in a dyno room with a 409 cubic inch V8 engine, even one just being broken in at light load is a very visceral experience.Angry Very cool and satisfying to see the beast come to life! Running it up a bit on the dyno, you can hear it flatten it's ears at about 4000 RPM....dang it sounds mean. For such a monster cam, it actually idles fairly smoothly at about 1000 RPM. My last AMX motor, with a somewhat milder hydraulic lifter cam, was much nastier at idle.

I'd hazard a guess based on what I saw today that more than 500 ft-lbs of torque is gonna be easy, we'll see about the 600 HP. More to follow.
