RE: f.a.s.t 90mm t/b
1) Don't try to convert to cable drive. It is possible but it will cost a fortune and will ruin the car for street applications/legal emissions.
2) The standard FAST 90 mm throttle body often gives surge and rough running problems. There is a modification involving drilling a hole in the throttle plate, etc. If you go this route anyway (you'll regret it) find a shop that knows the secret and have them do the mod -- takes 5 minutes.
3) The 90 mm Throttle body will actually hurt performance unless you have some serious mods -- a really great heads and cam kit of over 405 cubic inches, turbos, etc.
4) you have to have a 90 mm intake manifold to go with it, too.
