I know that I have sent this before but only a few people responded.

I went home this weekend to finish up the working of my Mustang. This is
what happened and why I don't have it right now.
I need ideas on why it would overheat.

After I drove the car for 30 miles the temp rose to the p on the temp
gauge. The timing wasn't too advanced, it was a dry warm day. I am using
new cooling system stuff. The pump has a little more umph than the old
one. The only thing that I can think of is that the air/fuel mixture is
too lean. On the Holley carb. there are only 2 adjusting screws. 1. Idle
2. air/fuel. How can I adjust this properly so that it isn't too lean?
After I rebuilt it I screwed the 2 adjusting screw in all the way and then
back off 2 full turns....that is factory isn't it. It also seemed to use a
lot of gas.

I just can't figure out why it would over heat now and not when the head
was failing and I had to floor it all the time.

Did you test the thermostat?
Are your hoses (heater mostly) routed correctly? I don't know if it matters
but reversing the inlet and outlet could be a problem.

Jason,
Have you checked your thermostat? If it is not opening all the way your
motor temp will slowly rise until it overheats.I often find the solution is a
simple one rather than complex

Are you sure that you got your head gaskets on the correct way? They
are stamped FRONT on one side and this MUST go to the front of the
motor. If one or both are backwards you will be blocking off the rear
water passages and this will cause an overheating problem. I hate to
plant this thought in your head because it means that you have to pull
the heads to make sure, but it seems too coincidental that this started
only after you did the head work.

Jason,

Did you check the float level? Too low can make it lean.
The screws only adjust idle A/F. To adjust the A/F at off-idle to WOT
you have to change the jets.

Another possibility: Did you get the correct water pump for the engine?
Late model engines with serpentine belts turn the pumps the other direction.
If you picked up one of those, it won't move much coolant and will cause
overheating.
