quite honestly. these types of posts get nothing accomplished.
ask yourself real questions when you have the block avilable.
and once you ahve the block ask yourself:
how much time and money do i want to invest in this car and engine?
how long do i plan to own this car?
is it financially possible for me to do this on a resonable time scale?
do i wanna go fast on the street or be more track oriented?
if you are asking what's going to be fast, it's a no brainer, turbo.
you got money to resleeve it? get all sorts of new parts you didn't account for?
