1984 Trans Am, Thermo Fans.

I had a thought to play around with my thermo fan.
now I have had a quick look at this in the past and I knew first time I saw it I would have to do some work to it, There is only one thermo and no fan shroud on either side of it.
I have been looking at wrecked cars and found that magnas have a 14" 4 blade and a 12" 6 blade the 14" is on when the engine gets warm and the 12" comes on when it is hotter, the 12" runs 2x the speed and flows like 1.5x the amount of the 14" one so I gutted two wrecked magnas and used the two 12" fans.
One is wired through the old wiring loom that the car had on the old fan but I hooked a small green LED light up to it and have it in the cab next to a switch, The switch is linked to a solenoid under the hood and is hooked up to the second fan.
Now the green light is there to tell me when the first fan is coming on and when it is going off so I know if I need the second fan.
170* normal, 220/230* real hot weather (45'C day) or when loaded up for a while (up hill on 38'C day)
Here is a little pic (wiring not complete here).

1984 Trans Am, Exhaust System.

The old exhaust (The factory one) was full of holes it now has coming of the 3" collector pipe a 3" to 2.5" high flow cat in to a 2.5" custom cat back exhaust with sports muffler and it sounds nice I have heard this exhaust with the Holley and the Q-Jet, the holley is a mid range note but very smooth the Q-Jet on the other hand is a mid to loud note and sounds mean and gets only 1/3 of the mpg the holley gets so I guess I will have to do some more things to get the holley / exhaust combo to sound meaner.

On that note in 2 weeks IM taking the heads off gona give em a full clean up and replace the valve stem seals and put thin mettle head gaskets see if it gets any improvement.
