Hey Chevyman. I've but a 468 (punched 454) in my '65. Used 80's model Hooker headers for BB. Send me your email address & I'll email some pictures. Headers where the biggest problem I found. Manufactors could not tell me what ones to use. See it the picture how well these worked. 1971 BB motor mounts worked.
