OK, What would be a better candidate for a stock displacement/ stroke 302 with mild cam, aluminum dual plane intake, and 5 speed manual trans? also i have stock 3:55 gears in now but pan to put my 4:10 in a few weeks.

now with manual trans would mechanical secondary be a better choice than vacuum?

with your listed mods I would go with a adjustable vacum secondary.

I do plan on a better flowing set of heads by the end of the season. What is the advantage vacuum has over mechanical?

Depending on what head setup i can afford but as it is looking i am gonna end up with a set of Windsor Jr's.
