My brother had one of these in a 67 firebird. 4 BBl and dual exhaust. It would go like hell. Speedo went to 160. I never saw 160 but I saw it well over 100. I would think that this would be an exellent swap into an AD. He had cam problems. I helped him replace 2 of them. After it ate the 3rd cam he sold it. Weeds.
