i sure the motor is out of a basic 86 gmc safari conversion van
the most common motor its sitting in a derby car now and it looks
like as its a regular motor out of a safari
i have a 4.3 chevy v-6 and i need to set the timing
i need to know the firing order and step to step basics to seting
the timing after puting the first spark plug a tdc
i can get the piston to tdc at number one plug but clueless after that
