Question: will ls7 intake fit ls3?
Answer: They are not interchangeable. An LS7 intake is supposed to flow better then a LS3/L92 and much better in higher rpm's. A Weiand L92 intake must be used on L92/LS3 heads, it cannot be used on LS7 heads the ports are different. LS7 intake must be used on only LS7 heads.
