What is the firing order for a 1981 Chevy Cheyenne 4wd with a 350 not a 1982?
4,3,5,1,6,2 The firing order of a 1981 350 engine is 1-8-4-3-6-5-7-2
Count two diodes from the distributor plugs (clockwise) that is number one. The firing order is 1 8 4 3 6 5 7 2 (clockwise) This is all regarding you have an hei distributor. If not its the same firing order, but the number one plug should be the one that points at the drivers headlamp, or no. 1 cylinder
I do not have a diagram of a 1981 Camaro with the 3.8 V6 engine. My link only goes back as far as 1982 and the Camaro had no 3.8 installed that year. However I posted a link for a 1982 Chevrolet Caprice with the 3.8 V6. The firing order and hookup is the same for this engine as your 3.8. Click the link to see a diagram.
Well to correct your post there was not a b2200 in 1981.It is a b2000.The firing order should be 1,3,4,2.This information actually applies to several mazda engines like the 1,586cc,1,796cc,1,970cc, and 1,998cc and last 2,184(the true b2200) from late 86 going into 1987.Amazing they all share 1 thing and fire order.
