This may sound like a noob question, but in the movie Bullitt, is McQueen pressing the clutch to go into neutral, then again to go into gear, with rev in btwn, or is he pressing it once to go from gear to gear, and revving the engine before letting off. And also, what is granny shifting? I'm a little confused.

he is whats called "double clutching" this is a technique used to reduce grinding of gearboxes that have helical cut gears and no synchros. Its very weird however due to the standard 4 speed in that car had synchros in 2-4 gears, leaving only reverse and first to not be synchroed. However in almost all modern road going manual gearboxes. Doubhle clutching is not needed.

I had heard the sounds were actually from a Ford GT (the LeMans race car)

I meant, what exactly is he doing with the pedals, and while I'm at it, how do you heel and toe, I read about it a while ago, and it may be a repost, but I forgot.

isnt granny shifting just the opposite of speed shifting? your just shifting to get where your going, nothing more

Appareantly it was taped over from a small block-powered Ford GT40 racecar, yeah. No idea why he's double-clutching.

EDIT: I should clarify that apparently only SOME parts were taped over. When he starts it up and is kinda cruising at the beginning of the chase it's the real deal.

Id always wondered if that was a real GT 390. I always thought that some of the sounds were quite a bit throatier (word?) than any 67 390 Ive ever heard.

think clutch to take the car out of gear, release the clutch, blip the throttle, push the clutch back in and shift into the next gear. and do it in about 1/10 the time it took you to read this
