it should
unleaded, 89 or higher for a vortec.
Yes.
89 OCTANE
Yes if the 89 had the same size motor as the 95 the 95 motor will bolt right in. The Chevy 350 did not change from 88 to 95. In 96 it went to the vortec 350 its a little different.
89 plus 43 plus 37 equals 169.
No. Not without switching the cylinder heads. I think it was 89, Chevy came out with the 1st generation Vortec heads, which require a different intake.
Yes an 89 350 will bolt up to original Vortec heads. However, Vortec heads have an 8 bolt inatke manifold that is different from the standard 89' intake. Its worth mentioning that the intake manifolds changed in 1986. Prior to 1986 all intake manifolds for a sbc had 12 bolts. These 12 bolts all secured the intake to the head at the same angle. In 1986, or primarily in 1987 the intakes 4 center bolts were changed to a steeper angle. With the introduction of the vortec head came a new 8 bolt intake eliminating the 4 center bolts. If you plan to use Vortec heads on any V8 be it a 305,327,350 or bigger, you will need a Vortec intake manifold as well. You can also buy an after market intake to run a carburetor on a set of Vortec heads in place of the TBI injection.
