Hey, just curious, I am currently running a dual point accel distributor and I am going to switch to a electronic breakerless distributor by MSD. My question is this, I currently don't have a vacum advance on my exsisting distributor and was wondering if I should go with one on the new distributor? Whats the pros/cons? I am running a 460 bbc with a lunati radical cam. don't know the lift off the top of my head probably a round a 538 or 588 I forget. any help would be greatly appreciated.

For street use, yes. For strip use, it's not needed but will not cause any problems.
