Rattling noise from engine compartment

[2000StreetRod]

A/C = 20 rwhp

Just for fun I hardwired the A/C compressor to stay on at WOT to see how much rwhp I lost. It was 20 of my stock 150 rwhp.

My first pulls on a dynamometer back in 2009 were done to establish a stock performance baseline.

Alright everyone, it has been a month since this problem started and thanks to your sincere prayers, the champ is still running strong.
Please keep praying for us!

Still running!

Sad news guys, I decided to work for Uber so I had to buy a new vehicle. I sold the champ yesterday.
The buyer checked the radiator and it was dry empty!!! while the coolant reservoir was full !!!! I'd always been checking the reservoir.
How's that possible?! why didn't the car overheat. I was driving it in the city almost everyday!

These trucks are tough.

Good luck with your new vehicle.
