Hi my name is Ali Mercedes-Benz 1977 left-hand drive please you are Explain firing oder thanks
The spark plug gap for your Mercedes is .032
it is 18435672.
450 series is far superior of the 400 series motors. 1977 450sl series is far superior of the 400 series motors.
DEPENDS ON WHAT ENGINE YOU HAVE.
The firing order is : 1-8-4-3-6-5-7-2
counter clockwise 13726548--------------------------------------------------- Ford Firing Orderhttp://www.aa1car.com/library/ford_firing_orders.htm
Basically all model years, 1432.
If you go to the library and ask for a Haynes Repair Manual you can find the firing order. I have a copy but do not have the means to send same to you. Good luck.
1-8-4-3-6-5-7-2
If a person bought a 6 prong fuel pump relay for the 1977 Mercedes 450 SL that needs a 5 prong relay, this will not work. The 6 prong fuel pump relay has to be exchanged for the right one. Inserting the wrong electronic parts may lead to a fire.
i believe that because it's a big block mopar, the firing order should be 1-8-4-3-6-5-7-2
1-8-4-3-6-5-7-2
