I just got off the phone with Greenwood, and they told me that the AC Delco P-25's will fit any 69 Chevy small block or big block. This was the filter the cars left the factory with.
There is only one thing I don't like about these repro P-25 filters, they don't have the anti-drainback valve like the updated "blue" AC filters. I guess if they worked great in 1969, there shouldn't be a problem with them today.
They also have the P-35's in stock, and they are about an inch longer than the P-25's.
