75mm Or 80mm Throttle Body?

[Tocchi]

before people go "TB's make no difference" etc, I HAVE to change throttle bodies.

I cannot run Fly By Wire for safety reasons (drag racing).

I have to run cable.

so basically, im looking possible throttle bodies.

should I stick with the standard 76mm spec TB, or a 80mm, or even a LS# spec 90mm one?

now, remembering im currently running:

powerglide with transbrake

gt3540 with 6boost manifold

nitto plenum

so low down power I dont need.

which would be best for high power applications.

cheers
