hey, I'm thinking about upgrading my throttlebody and MAF on my 91 this christmas...

what would be a good size/brand for an internally stock 5.0 with bolt ons (stock intake)?

how much power do I get from upgrading? 10hp...more?

and lastly... I was peeking under the car the other day and noticed the driveshaft was not crusty like the usual steel shaft would be... does this mean its aluminum? I'll have to geta better look/possibly a pic tomorrow

Dont expect to feel it in the seat of your pants, that upgrade usually give you a few horses perhaps but it really picks up when you change intakes or port them better flowing..
