in the near future Im looking to put a thumpr cam kit into my 305 sbc (1983 camaro, stock heads, edelbrock intake, and 600 cfm carb 4b, shorty headers)

i have a few questions for this:
other than what is included in the kit, will i have to purchase anything else for the installation (other than lube) or make any adjustments?

also, the vacuum with this cam is low, so will an independant vacuum source be needed for power brakes and the carb/advance and such?

ive never experimented with cams before so i am in the dark here!

thanks for any help guys!!
keep 'er squealin!
