At what horsepower level do I need to swap from 65 mm to 70 mm? It dynoed 300 to the wheels with a 65 mm on a 306
H/C/I combo with long tubes and a 73mm C&L.
I've been told to go with 77 mm pro m and a 70mm throttle body but I do not want to sacrifice throttle response or drivability.
I've been told I would make significantly more power with no sacrifice, agree??
Of course I will have it retuned, I may go with bigger cam in which case I will most probably go with the larger TB and air meter.
