Vacuum or Mechanical Secondaries?

[pauls340]

Mild 340 with stock intake, electronic ignition, stock exhaust and a 4 spd. I have a 650 mechanical secondaries spreadbore and divorced choke now. For just street cruising is there an advantage to vacuum secondaries?

Yup. With a mild engine and an automatic it will be faster with a vacuum carb. Might be faster with a manual too.

street cruising with wot throttle involved?

or just street cruising/driving?

 

[pauls340]

street cruising with a few short burnouts...

you are fine with what you have, though on the small side, tune it.

if changing carb, get a 700 vac sec.jmo
