can you run a street car without the vac adv can. i don't have vac adv anyway because the promax kit for a 6pk does not have a port for vac adv but can i take off the vac adv pod off the distrib?

In general answer is no, you don't want to remove the canister. It holds the advance plate inside the distributor, without it in place, the v-adv. plate would move freely, playing havoc with your timing. I'm sure there's a way you could fix the plate.... but you're on your own with that one.

I took a section of vacuum hose and pressed a plug into it at the carburetor end. Visually, it looks like all is hooked up and operating, but there is not actually any vacuum being applied to the distributor. (I like a finished appearance under the hood )

Yes though it'll hurt your mileage if that is a concern. Leave it attached or if you want to remove it for aesthetic purposes you'll need to go inside the dist & drill a vertical hole thru the 2 plates & connect them w a mini bolt/nut w a sleeve on the bolt in between the plates to keep the plate level as you tighten it appropriately to lock em solid and this is the perfect time to check/correct phasing as you can shift the eccentric plate and drill/pin/lock it down where you want it EDIT fab a thin alum plate to cover the hole

The outside cover plate is an easy one...Just get the cover from a lean-burn distributor...Then the block off will look factory...

thanks guys. i put a a/c unit on the car and the air cleaner base contacted the suction hose. got another hose so as not to have to cut the air cleaner base. the other hose contacted the vac adv can on the distrb so my choice was to cut the air cleaner base or no vac adv can. if i was to lock the plates toghter would you position them in the most retarded position or 1/2 way to full adv or what? thanks

Drill a 1/2" hole in the top flat of the dist cap about 2/3 of the way from the center terminal closer to the #1 terminal and shine your timing light down on the rotor blade at idle which'll freeze the rotor like a strobe light will on a dance floor. Note if the blade is dead on w the underside of the #1 terminal & if not is it pretty close or way CW or CCW from it. The can shifts it (from that point) CCW on a SB and CW on a BB. EDIT assuming ported hookup. Use a mityvac or similar vac pump & pump up the can by hand till it shifts it just enough till it is lined up as good as it can b made to & note the vac needed to hit that exact point then take it out/apart & pump in that amt of vac to locate the plate at the same point & drill/pin em. Now if you need to shift it CW on a SB or CCW on a BB forget the can and you'll need to dissassemble the plate and move the eccentric plate the opposite & it'll take alot more work as you'll have to mock it up/pin it & recheck. Depends how far off the phasing is/how meticulous you are in getting every subsystem spot on. I would also narrow the rotor blade to 1/2 of it's current width and extend it w solder/liquid steel to reduce the tip to cap terminal clearance to ~.030" as any spark in that gap is wasted energy that is better put to use in the cyl. Would it b possible for you to get an A/C air cleaner (or mod the A/C hose) so you can keep it

I ran across a distributor the other day with some of the same issues you guys have been talking about. My motor came with the distributor on the right which had the block off plate and the inside plates were screwed together. What was this used for? was it a aftermarket kit?

Screw was holding the two plates together. Was this a kit?

No, someone did this mod & check that there's a sleeve slid on the bolt in between the 2 plates so it doesn't tilt as you tighten it down the right amt. Your ACE hardware store will have what you need

I put a couple welds on the plates to keep them from moving after the advance pot is removed.


The first one I ever did I screwed and nuts to keep it together.
