1111194 distributor

[Timothy B.]

Put a new advance curve in my 67 300HP distributor.
0@900-10@1500-16@2000-20@2500-25-26@3000. I used the light silver springs with a 728 weight base and the weights in the kit. Also installed a MS 163 advance control because the car pulls 19" vacuum at idle, specs are 0@10-16@16 1/2"


Took the plunge and installed the breakerless ignition and did away with the points. I plan on setting the total timing at 36* and I expect the inital to fall around 10-11* BTDC

Re: 1111194 distributor

I believe your dist. should have 30 degrees total centrifugal. My specs say the 163 requires 18" for full advance and some require 19", which could cause variable idle timing and idle stability issues - suggest you test.

I recommend a 15" VAC for manual trans and 12" for Powerglide.

A 12" VAC was OE on all 327/300s in '66 and '67, regardless of trans type.

The weights in many or those cheap aftermarket kits are not hardened and have a reputation for wearing the pivot hold. It's best to use the OE GM weights. The design geometry of the aftermarket weights can also increase or decrease total centrifugal relative to the OE weights.

Re: 1111194 distributor

Duke, I tested the vacuum control and 16.5" pulls it pretty tight. I really did not want to use this control but with the curve I wanted to avoid the rattle on accelleration.

The other curve I had considered was with a 722 weight base and I filed the slot just a very little, #37 weights like our 63's and the light silver springs.

Tim;

Isn't it nice to have a distributor machine available so you know what you've got - no guessing. I'd be interested in hearing how your electronic kit works out for you too - chopper w/hall effect from the looks of it. How well do the blades line up in the pickup slot?

Re: 1111194 distributor

Stu, It's the Breakerless from M&H and it took 10 minutes to install. Everything lined up perfect, no problems.

I will let you know how it runs, I expect like a new set of points all the time.

Re: 1111194 distributor

Tim;

Thanks. I've been running kits in mine since the mid-70's with great results; first Prestolite (marketed by Montgomery Wards), then Pertronix (original, now their II model). The Prestolite unit had an outside box a real bad pin type connectors that would break internally. Otherwise, it was the Hall Effect and worked great.

What coil will you be running, and what voltage input with your M&H kit (ballast resistor or not)?

I can't begin to tell you how much peace of mind you will get from this change, not to mention the knuckle busting spark plug changes you'll avoid, and the ability to stab it to redline on a highway traffic merge after idling in stop n go traffic. It's a great feeling and will let you enjoy your Vette a whole bunch more.

Re: 1111194 distributor

Stu, I will be using a new GM #202 coil with the ballast. The information sheet in this kit instructs to use the ballast and I want everything to look stock.

I don't know if the spark generated is as hot as the Petronix but the dwell will be perfect and the hall effect switching action should be a big improvement over the points.

This along with the carburetor shaft bushings and advance curve altered, heck, you wont even see me go by...

Go for it Tim! Sounds great! You're off to having a great summer with your Vette.

Put a new advance curve in my 67 300HP distributor.
0@900-10@1500-16@2000-20@2500-25-26@3000. I used the light silver springs with a 728 weight base and the weights in the kit. Also installed a MS 163 advance control because the car pulls 19" vacuum at idle, specs are 0@10-16@16 1/2" .....

Just to bolster a few of your and Duke's numbers; data from Delco Remy Test specifications DR-324S-1 and 2, and their supplements.

Your "194" distr. would have had a 1116355 vac can, originally. 5 to 7" Hg to start advance; 16 deg max crank advance @ 11.2 to 12.7 " Hg.

The 1116163 can, however, has 8-10" Hg to start advance; 16 deg crank advance max. @ 16.25 to 18 " Hg.

Centrifugal, with factory springs and weights on your 1111194: zero to 6 crank degrees at 1000 crank rpm; 3 to 9 deg @ 1100 rpm; 13 to 17 deg @ 1500 rpm; 28 to 32 deg crank @ 5100 rpm.

Re: 1111194 distributor

Thanks Wayne, I tested the 163 vacuum control and it's pulled to stop at approx 16.5" that's why I used this one. I have all the original distributor parts and the specs you quote for the 194 sound like about what I measured. If I decide to switch back it only takes a few minutes.

I hope to start the car soon and I am curious how the advance curve will run with the stock engine. The car ran strong before, 300HP is a nice street engine. Now if only that Holley will behave itself...
