Timing for 1990 1500 with 4.3
if the specs are the same as they are in '94 which I wouldn't see why they would change them it's 0 degrees btdc.
you turn the distributor and use a timing light
It does not have one.
I have a 1990 and factory setting for base timing is 10 degrees, I believe.
The 1990 has a chain. The 1991 has a belt.
1990 through 1998
88 through 99 are all the same.
It is in the throttle body.
Should be the 700R4 transmission.
in the engine block
It does not have a timing belt. The cam is chaindriven.
