Do you happen to have a pic of the Firebird center link?
I believe the BBC Maro center link is more curved than the bird. Unfortunately, the Maro center link will not work with the Bird inner and outer tie rods.
Marble Creek, Banshee wasn't directing his challenge to you.....it was to "Ponchobird".....funny name for someone preaching about Chevy power.
I'll put my "mostly stock" budget 455 up against a BBC 454 with less than $3000 in the motor anyday......no power adders.
