Guys - acquaintance of mine is considering downdraught webers on his 351W, wants to know what he should consider before going that route.

My own thoughts are:

1/ Expense and difficulty of setting up (need to find someone who can set them up)

2/ Headroom under hood - the car he is considering can just squeeze a performer rpm and holley 4V carb with oval (shallow) Cobra air filter under the hood - are webers on their appropriate manifold taller than this?

3/ Potential need for custom cam grind?

4/ Difficulty in arranging vacuum take off for brake booster.


Anything else to be considered?? Thanks in advance.
