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.
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.
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.
no you cannot they are not interchangeable the 89 heads are fuel injected heads and the 79 are carb heads and will not interchange
yep
Your question is a little vague, so im assuming you're asking which is better between 350 and 305 heads. Many people will tell you it doesnt matter. I think if you have a 350 engine then you should use 350 heads. the 305 heads will have higher compression, which will make the car louder, and somewhat faster, however, if you use 305 heads on a 350 engine then you should use a high octane fuel, so it will be better on your engine. Only use 305 heads if you know what your doing. if not you should probably stick with 350 heads. i hope that answered your question.
In 89, Chevy introduced the 1st generation vortec head. It has a different angle, thus using a different intake manifold, and self adjusting rocker arm.
it should
Only if you also use the 89 cylinder heads.
yes it will
350 = 4.000" x 3.48" (Gen.I, 5.7" rod) 350 = 4.000" x 3.48" ('96-'01, Gen. I, Vortec, 5.7" rod)350 = 3.900" x 3.66" ('89-'95, "LT5", in "ZR1" Corvette 32-valve DOHC, 5.74" rod)
YES. They are the same engines. It will bolt right up as long as the 95 had a V-8 in it.
