I used to pull the top two bolts first, from the top side with a gear wrench before putting the car up in the air. I was carbureted and had plenty of access though.

So jrad came over and we believe the sound was actually coming from the upper intake. Swapped gasket, started car, noise still there and won't change in different gears or with revving. He went home. I went to crawl underneath to verify bottom-up that the noise gets louder as I move toward the engine. Start car, no noise. No amount of running will make the noise return. I don't get it.

Transmission line pressure seems fine as I shift through gears: https://www.youtube.com/watch?v=uNP8c8i5xbY

I will measure the other pressures tomorrow to verify. I'm not worried about the trans as much now that I know it has adequate pressure.

Main Line Pressure

In P/N, OD, D/2, 1 @ Idle Hot - 50 to 75 psi
In P/N, OD, D/2, 1 @ Stall Hot - 160 to 210 psi
In Reverse @ Idle Hot - 80 to 120 psi
In Reverse @ Stall Hot - 220 to 280 psi


I have 77psi pressure idle, 200psi stall, 110psi reverse, I haven't tested reverse stall.

Pulled out, re-checked some things, put back in. Had flexplate/converter issues this time, but got it all in. Still runs fine. I'm more comfortable with everything now, and with new loctite, everything is reinstalled correctly.

Planning on taking the car out for a short sprint tomorrow. Very short - new exhaust parts will be here next week. For now, open headers.

On that topic, I believe most aftermarket midpipes have clearance issues for the shifter bracket in automatics. Anyone run into this issue before? What is the "best" fix, rather than chopping off half the bracket?

Took car out today, immediately came back after getting onto the main road, put old exhaust back on. Open headers and 3k stall is not nice to anyone in the general area.

On another note, nice to feel how power comes on in a v8 again. Transmission appears to work fine. I'll need to find my new dccontrol thermister before I drive more. Can't go far without cooling!

I'm glad everything is getting sorted out. Sorry I didn't stick around longer, I was getting sick and had a lot going on this last week.

 Even I didn't dare drive mine with open exhaust all the way to the exhaust shop. I had slip joints fabbed where I cut mine off and just clamped it. That was loud enough going down the highway.  :)

Found my stuff to get the fan going again. Now just that pesky whistle which came back. I'm looking at the pcv area - it could need to be pressed in further. Dumping water at the front of the lower intake, so it flows to the back, didn't seem to change anything. Lower intake gaskets should be fine.

I had a similar issue when installing my Monster AOD. As I was tightening the case bolts up,it would lock the cranktrain down on my 351 Cleveland. I thought perhaps I hadn't shortened the input shaft enough as the guys at Rev-Max had instructed. After being in and out of the car 2-3 times, I placed a piece of angle iron across the front of the bellhousing and measured how deep each component that engaged the converter was. Turns out, my Monster had more clearance on the input shaft, the pump gear depth, the direct input...all good. The problem was a change in the way the stator support was machined. The Monster pump had a more rounded area in front of the splines and that was bottoming out in the converter, making the converter sit too far forward. Some very judicious clearancing with a Dremel got the clearance opened up. The two components spline together and are locked, so you don't need to worry about the "machined finish" as the two compnents are in a "fixed" relationship.

Yeah, I don't really care now that it's resolved. Not sure what happened exactly, but the transmission works great in a new case. I didn't even have to touch the transmission pump or converter - they looked and work fine. Also found that my oil leak back there was due to ALL of my engine oil pan bolts loosening up. Some felt like they were no more than 2-3ft/lbs. Was worried after installing a crank sleeve and new rear main seal, and then saw oil in the back again!

There are bigger things to worry about now. I hope to get the motor purring, rather than sputtering.
