89 s-10 blazer

if any body knows anything about these please help me out

as far as i know they only make them for the newer 4.3's but u mite be able to make one of those work???

summit has them, but they vary depending on if you have the 262 or 265 size of 4.3L. i could only find them in roots style, not centrifugal (turbo-style)
