I have a dist P/N 1111263. 7 H 31 that is set up for Transistor Ignition (TI) K66 Option. It also appears to not take a vacuum Advance pod. ??? Any ideas what I picked up today? My books show nothing. Thanks

 

It was built in August 31st of 67, so it may have been used on a 67 or a 68. Are you sure on the numbers? My books also show nothing.

I found the following on the Internet about this Dist. Listed for $1699.05 in 1991, WOW!!!!

The "Delcotronic Transistor Controlled Magnetic Pulse Type Ignition System" is seldom, if ever, seen or discussed, but it was a key part of Chevrolet's racing success during the late 1960's and early 1970's. This special transistor controlled ignition system was developed for high performance and racing use to replace the traditional point-fired ignition system found on regular production vehicles. This first electronic ignition, known by such names as Magnetic Impulse, Mag-Pulse, Transistor Ignition, or simply TI, became the standard in heavy-duty high performance Chevrolet ignition systems.

An alternative distributor was also listed. This is the highly prized ball bearing distributor PN 1111263. This heavy-duty version was initially released for the reverse-drive camshaft 427 big block racing engine. It has a special ball bearing on the upper part of the mainshaft instead of the usual bronze bushing. This distributor has an iron housing with a mechanical tach drive and has a special reverse-drive distributor gear that permitted clockwise rotation of the distributor in this special 427 engine. It specified 13 degrees maximum mechanical advance at 1900 RPM. This distributor did not have a vacuum advance feature; the plate inside the distributor was fixed in position. (This distributor was still listed in the 1991 Chevrolet parts books, for $1,699.05!)

The 263 distributor required two changes for use in the small block 302 engine. First, the provided drive gear was replaced with the standard drive gear. And second, the lower oiling channel on the lowest boss was extended full circumference. (As supplied by Chevrolet, the lower oiling channel traversed only 3/4 of the circumference; if not fully grooved - like the standard small-block distributor - the oil passage that feeds the right-side camshaft lifter bank could be blocked, resulting in immediate engine failure!) In addition, it was often desirable to revise the provided advance curve to better match a given application. (Most racers changed the advance curve anyway.)
The 263 ball-bearing distributor had an advantage when the Cross-Ram dual 4-barrel setup became available for the 1968 Trans Am racing season. Because the 263 didn't have a vacuum advance unit it was easier to clear the number eight runner on the Cross-Ram manifold. The distributor tach drive could be moved around to suit the application. The previously mentioned 267 distributor can also be used, but it is a much more difficult fit in the Cross-Ram manifold application.

Now I need to Break the code on "heavy-duty version was initially released for the reverse-drive camshaft 427 big block racing engine" hmmmm

 

I hate to spoil the "mood" but the #263 is neither rare or valuable (I have two of them), it was NEVER used in a Corvette so its value is low compared to the inflated $1600 list price. For some stupid reason Chevrolet placed (and continues to place) a very high premium on their race parts, ie: blue MSD boxes & HD MSD distributors with GM part numbers for lots more than from a Summit or Jegs. The other downside to the #263 is the internals are not the same as a standard Chevy TI. ...redvetracr

 

I wasn't leaning so much towards the rare part as I was the price. I ran across 3 today, this one being the only complete one. Is the Statanary (sp) part the standard TI setup?

 

Sort of, if you look at the bottom of the magnet you probably will not see a hole where on a standard TI magnet the vacuum advance can hooks into. The rotating pole piece is also different as is the main shaft but that little bronze/brass washer is the same. Do the wire leads coming out of the magnets have the factory ends?? and a whitish plug?? ...redvetracr

 

Redvetracr, yes the leads are factory correct, white / green with clear plug. I dropped T.I. Specialty a e-mail to see what he could do with this. Maybe trade-in / swap-out / cash, I just need a TI setup that will work with a 69 427 / 435hp car. This is the missing link right now.

 

I have a very nice restored 1111928 8J23 correct for a 69-427/435 if your interested $500. delivered. I also have a real nice amplifier box and TI harness for a C-3 $210. ...redvetracr
