ooh, if you're new at this, a TT motor is gonna be biting off more than you can chew IMHO.

you'll need a forged crank, good main bolts/studs, H beam rods say, good rings. More specifications than "a racing cam". In fact, a non racing cam might work best, or a custom ground one.

o-ringed heads maybe. Big chamber heads, etc.

it all depends on what you are willing to spend

eagle makes nice forged cranks
you could go with a fresh bore and turn your 350 into a 383.
H beam rods are easy to find
as sonix said a more mild cam works best in FI situations
Youll need a turbo kit or build it yourself
youll also need a different ecm or stand alone fuel system
keep searching and researching and youll find a ton of info on this site
