Pipe length

[Ray Sametz]

Been about 4 years since I ran single F-hydro. Have a 80 CMB greenie with an original AB 67 black pipe. Need a good starting length on pipe? Thanks..........==={}

11-1/2"- 12" and depending on your prop... H-32 with that engine will work nice in heat racing...

.010-.012 should be fine.I ran a .550 carb (large spray bar)on a greenie 67 and it ran great. you should be fine.
