nothing. but the intake will be diff.
Answer The 86 Chevy block and the 87 Chevy block are the exact same block, nothing changed, it will fit perfectly.yes
As long as the 350 is older then a 1987, you will have no problems. They will bolt right on with no modifying.
That's what should be on it.
bolt them on their the same
No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
If the intake mates up with the heads. then yes. Mating depends on the year of heads.---------------------------------------------------------------------------------------------------------------It will require bigger injectors and matching ECM however to run optimally.
they came with "186" casting number heads.........
lt1 is a 350
no
The headers for a 350 and 305 are the same.
Yes you can but you will need to modify the bolt holes in the intake manifold. The TBI intake 4 center bolts, 2 on each side will not line up with the heads. Must drill them out just a little.
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.
