which distributor for Turbo 200

I am looking to pick the correct distributor for my car.

Autozone has a 30-2690 single vacuum or 30-2670 dual vacuum.

I have read where I will need to get the mr gasket 925 sprigs and put in only 1 of them.

I plan on running a MSD 6AL along with the Holley Blue Fuel pump and fuel pressure regulator.

I am running the iSKY 256 Cam which has 202 @.050, 450" lift, LSA 112. i am also going to run the Holley 8007( 4bbl progressive, 390cfm).

I am also running the OZ2V head. I have ported and polished the head. mirror finish on the exhaust and rough and scratchy on the intake.

all that said, which distributor?

Use the MSD Digital Programmable 6AL-2 Part No. 6530.
Just lock out your distributor so it only has to supply a reference signal and let the 6AL-2 control the timing curve.
You can program the 6AL-2 timing curve for boost as well as vacuum on top of the mechanical advance.

If you need to make a change to either curve it is just a matter of programming.

At 15 lbs boost you will be forcing 1 lbs of boost into your fuel tank. You need a efi pump. This is you assuming that you are doing the modern blow thru.
