Sorta.The MC is matched(size wise) to the capacity of the calipers & rear cylinders to provide enough fluid.Gross mis-matching would let the MC run dry during application with mileage on the pads.
2 alternators or maybe 3
3 volt regs
1 front trans seal
2 set breaks
2 rear wheel cyliners also drums
3 slaves cyklinders
2 break master
2 clutch masters
1 speedo cable
2 dizzys
Front cover-corrosion i'll bet is from lack of maintenance
Those are all wear items.
I paid $400.00 for my 810 that i just scrapped.Once i figured out the computer solder joint issue and brought the cooling system up to spec to deal with Tucson heat,i put 45,000 miles on it without it leaving me anywhere.
You really need to research exhaust theory before getting in a discussion like this.Exhaust science is just that -a science.And Mike is correct.The gases don't "hit cold air" until they have left the tailpipe.
Exhaust gas leave the cylinder in the neighborhood of 1400 degrees.Guess what it's temp is by the time it hits the muffler?
