I had been working on getting my AC charged on the 73 vert. Took forever to find the leak which was the high pressure Schrader valve at the service port. My AC compressor does not have the isolator valves just the hoses and hook up for gages. So I still have a leak somewhere that does not show up with black light so might be in the dash so I quit working on it.
This car sat for 27 years so I thought I would pull the Holley carb off. When I did I found a bad gasket or a wrong gasket. The PO lived in California and to keep it legal he put an EGR plate under the Holley configured for the spread on the Holley. The issue is that the Edelbrock 2-V head to 4-V intake does not have enough material to close off the EGR plate in the rear. So it had both a vacuum and exhaust leak going on. I thought it was a header gasket leaking.
The Holley had a list # of 7154 which I finally figured out was a 4150 model Holley. Summit had the best price for the rebuilt kit and also the transmission cooler and should be here today.
So looking for suggestion of spacer plate to go back with without the EGR port. The current plate is 7/8" thick and has 4 holes to match the Holley.
Is 4 hole better or one with just the big square opening? The intake has the one web in the center going front to back, see pic.
Carb Renew kit should be here today and I also ordered a Hayden fan cooled AT cooler to get the heat from the transmission out of the radiator.
I have been running the Lucas gas additive and the inside of the intake and the intake ports are all oily also. It did make a huge difference in the operating temperature of the engine.
Me and friend checked the vacuum on the engine at idle and it had 15 lbs. which surprised me with the cam that is in it. I have no idea of the spec or make of the cam. It does run good enough to turn the tires when it goes into second at about 50 mph.
It is amazing how many things the PO did wrong on building this car. I expect the engine to blow at any time but I have two more sitting on stands now so not going to worry about it.
Want to drive it to the MOM, Mustang Owner's Museum end of this month to all Ford show and the Carpenter Museum will be open that afternoon with the Hornet's Nest AACA club meeting there. That is about 250 mile round trip so I want to be more confident in the car.
