307's have always been a "red-headed stepchild" to many folks,I bought a new '69 Chevelle Malibu 307 with 3 on the tree and 3:73 gears a year later I was going through a divorce the guy I sold it to held an NHRA record in J/Stock for nine months. So for $200 maybe not a bad deal after all for a street cruiser just use the good oil and STP has a ZDDP formula at Wal-Mart for under $4 bucks you can add in.
