Got mine from Mancini at the Chrysler Classic one year. Don't remember what it cost. I do know I didn't pay any shipping! Had one on both a small block and a big block and both had headers. The big block has tti.

1969 Super Bee X9 N-96

Looking for the original block for my Bee. The last 4 are 7449
