Brake lines done. Bleed in the morning. Go install cabinets in remodel next. Get back and install engine. That’s the plan anyway...

I don’t know the p/n of the ATI balancer. I’ve had it since I started racing this car in 1998. It’s 6.65” diameter and uses SBC bolt pattern on the front. That’s a 6.25” MSD crank trigger wheel I just bought. Previously I had an 8” wheel but was not running a motor plate. Now I am and that .310” plate and the Meizeire water pump adapter stacked on top of the motor plate interfered with the crank trigger wheel. Needed to mill .140” off something and I was not happy with that. Called Adkins and he’s the one that told me I had the wrong wheel! Didn’t even realize 6.25” was an option. That took care of that. Of course then I had to slightly re-engineer the trigger mount due (built on the fuel pump cavity) to the smaller diameter of the wheel. I’ve got .060” clearance from wheel to trigger but am not entirely happy that the arc of the trigger adjustment is different than the arc of the wheel; i.e., if you retard the timing (down), it gets tighter from trigger to wheel. If you advance the timing (upwards adjustment), it gets way to wide. But in the end, I decided .060” was adequate and any timing adjustments are through my MSD Grid and laptop anyway so it shouldn’t matter. Previously I did not have the Grid so I would make adjustments by moving the trigger up or down on it’s bracket.

I’m not aware of any shelf item crank trigger system specifically for AMC.

 
OK thanks for the information!

Couldn’t find time this weekend to do the brake lines but I did get the dog house all cleaned up. Amazing how a coat of VHT Chassis Black can help! Took a wire wheel to the crossmember, lower control arms, strut brackets and new motor plate mount then painted.  
Trial fitted my new C & R Radiator I had made. That Spal Fan just barely clears the upper & lower radiator support and closing the hood gives a finger width of clearance. I went for cooling over weight this time.  
 

 

 
I have plans for an NHRA 360 in the future. I will report on that NASCAR block in the future. Want to sonic the cylinder walls and deck. I will build it as a back-up spare short-block.

It is a Saginaw pump, replaced because it was leaking around the shaft.  I will look up the info suggested and see if that help.  Keep the help coming.
 
Thanks again,
Craig

Looks fantastic! - if it goes as good as it looks will be awesome!
 
What crank trigger setup have you got? and which ATI balancer is that?

DONE! Finished off the engine today. Crank trigger is set up. Oil pressure was 60+ with drill (cheap gauge only goes to 60#. I think I broke it as it went past 60# and now it’s stuck at 10# just sitting there). Oil to all rockers. Found a card at the local pizza joint for a polisher here in town. Recent transplant from Illinois. Obviously I tried him out and WOW! Not sure how well the bling goes with my “industrial” look but I like it.  
Will work on redo of brake lines (front to rear) tomorrow.  
Dang! Missed the Arizona Stock SuperStock Race which is tomorrow. Oh well. I just pray this runs good! Will report on that SOON!

What was the reason for replacement?   I replaced a pump in my Jeep only to find out the hoses had deteriorated inside and the pieces of rubber were jamming the rotary valve in the steering box itself.  The new pump was destroyed in short order.  Ended up replacing pump, hoses, and steering box the second time.  You might want to check hoses and fluid for contamination.

Saginaw or Eaton pump?? I believe Saginaw was stock on the 1972 models, but never hurts to confirm.
 
Sounds like a bad pump to me. Rebuilt by Cardone by chance??
 
If you think it is a pressure adjustment problem, google Saginaw pump pressure adjustment, you'll find lots of info. It is fairly easy to do.
