First, I hope you're aware that the 67-68 FB is the most popular body style now, thanks to Elenor, and that finding a car worth fixing will cost you at least $9k. The Hipo was in its last year in 1967, and production was LOW, and IIRC only 4000 or less FBs got a Hipo. The 302 didnt become technically availible until 68, you could get a standard 289 in 67 though.
