Can anyone tell me where this distributor, part number 111196, is off of? In particular, I'm trying to find out what the built in advance is suppose to be.

Re: Distributor 111196
1111196 specs: Advance start 500 RPM 0-3 degrees, @750 rpm 6.5-8.5 deg, @2550, 14-15 degrees, all are distributor degrees and distributor RPM, so X2 for engine numbers. Vac advance "236" can, Advance start @ 3-5 inches, max advance 8.2 deg @ 5.7-8.3 inches. Again dist degrees so X 2 for engine degrees.Bill Clupper #618Comment

Thanks, but do you happen to know what the advance is suppose to be. NOT the rate I know that is controlled by the springs. I have this distributor in my car and by checking my timing with a dial back timing light, it is showing me only 18 degrees ( 30 total= 12 inital +18 dist.). Also I "m not sure what the "sp" acronym is. 18 sounds a bit low to me. I figured more like 22-24 degress should be there. I 'm trying to find out if that is correct or if there is something up with the distributor. Something is going on with my car and I not getting enough timing in the car, looking for that 34-36 degrees total with out running crazy intial timing.Comment

Re: Distributor 111196
Bill thanks for the info breakdown. Sorry to sound clueless, but I undestand ( I think) the dist. is 1/2 the crank rotation. But I 'm a little confused then on those spec and my findings. My finding of 18 degrees was at approx 3000rpms. What am i missing?Comment

Re: Distributor 111196
The stock ignition spec for a 111196 @ 1500 RPM is 15*. The curve does not total out till 5100 RPM @ 30*.

Re: Distributor 111196
Donald has it, my numbers were distributor RPM, which is the way most distributor specs are expressed. Multiply X2 to get the engine speed needed to approack those advance numbers. (also the advance numbers will be X2 as you noted.)Bill Clupper #618Comment

Re: Distributor 111196
Thanks guys. I got it. But shouldn't the 30* @ 5100 rpm change when I put lighter springs on? (recurved) The springs I put on were suppose to get it "all in" @ 3000 rpmComment

Nope. The springs only determine the RATE of advance (shape of the curve); the total AMOUNT of centrifugal advance (end of the curve) is determined by the length of the slot in the weight plate, size of the bushing on the limit pin, the shape of the tail on the weights, and the contour of the plate on the top of the mainshaft.Comment

Re: Distributor 111196
The answer to that is a big "maybe" If the distributor has been rebuilt over the years, different parts have varying capabilities, also some of the aftermarket "kits" especially weights, have negative issues (reduced travel and thus reduced advance) Also if the mainshaft has been replaced, there are "high perf " and "base engine" designs for the cam attached to the top of the mainshaft. Best way to set one up is with a machine, off the car. Much less hassle.Bill Clupper #618Comment

Re: Distributor 111196
Thanks guys. I guess I will be spending a night taking it apart to see what the heck I got. Are there part numbers on the weights to see if they are correct?Comment

Re: Distributor 111196
No, but aftermarket Weights are generally plated, and GM weights are bare steel for a start at least. Also the typical wire diameter on GM springs is about in the .030-038 diameter range, although there some variances, Aftermarket springs are generally made from much smaller diameter wire. The use of either or both in combination can really mess up the factory planning for the proper role of the Distributor.Bill Clupper #618Comment

Re: Distributor 111196
Nice website with the tech data. So now I know my 1112247 dist was origianlly in a '74 195HP 350. Can't explain the 3K2 date code though. If it was made in 1972, how would it be in the '74. Anyway, it's not the 111141 I need for my 66 390HP!
