Why is it that nobody seems to have or care about 2nd gen chevy small block V8's 262-400 ci. . I mean there used to be tens of thousands of them on the road in C3 and C4 corvettes, camaros, caprices, impala's, chevy and GMC trucks and so on. I did manage to locate Fram XG30 filters for my LM1 interceptor motor but there hard to come by. There were I think about 60,000,000 of them made ?
