Leigh,
Why does the scoop on the 77 say 3rtil d.d?
Rich,
when dad brought the 77 home, my brother has his 73 Brewster green 455 and an AB 74 400, so it REALLY looked weird since there were not a lot of 77s around yet.... and it didn't WOOP as loud when you hit the gas.
The biggest difference in sound I ever had was when I had C&C tops cut inot my 76... first time I stood on it I nearly wet myself.... gas mileage was really bad for a couple weeks......
