No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
lt1 is a 350
no
The headers for a 350 and 305 are the same.
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.
NO not even close.
No. The bore size is different between a 305 and 350. The 350 bore size is larger.
the heads should fit as long as your not trying to put them on a big block
350 Chevies were offered with heads made from iron or aluminum.
