Distributor setups for L78 or L72 engines?

[WILMASBOYL78]

I use the Crane setup in the 68 yellow BB car..it works fine and has the rev limiter feature which works nice. All the other cars have stock points style dist. with just regular parts. I did notice on the L78 distributor the vacuum advance had 15 and 3.55 stamped on it...I assume that is the 15 degrees mentioned and guess the 355 refers to the rear end gears?????

I want to check the curve on the project car and set it up correctly...that is my next tuning adventure.

Tom,

With a decent dial back timing light and tach you can plot the curve through any rpm range. Its fairly easy to do. I use a snap-on light that gives both timing and rpm.

Wilma,The 15 stamp on the vac.unit is the advance it pulls in.The 355 stamp is the last 3 digits of the vac.unit part #.
