Re: LARS: TOTAL TIMING FOR BIGBLOCK (Tom454)
MELVIN, with Lars' instructions, you should be able to check the amount of mechanical advance you're getting. You should check it. When I checked my stock L36 distributor, I found that my mechanical advance was giving 34 degrees of advance. This is too much, since you'll only be able to run around 2 degrees initial timing to keep the total at 36. I think the factory did this on purpose, since my L36 stock spec is for 4 degrees of initial timing. They run better with more initial timing.
The fix (with Lars' help), was to weld a little metal to the slot that the bushing rides in, then file it to the correct, smaller size (lars has the spec.)

Hi Lars..
I had emailed you a week ago about tuning info. Im the guy with the mallory dual point that wanted to swap it for the MSD probillet w/tach drive and 6a module.
It showed up at my door yesterday..whooowee..Its an awsome looking setup.
I was real surprised at the size of the module though , its a huge and weighty box, I had thought it would be smaller. Ive gone through the installation of both parts and its real straightforward, ...except the getting it tuned in to my system part :eek:
Ill be putting it in tomorrow and referencing this post with a magnifying glass as I try to time it. If I get confused :confused: (Im not at all intuitive with correct timing procedures) especially with why to change the weight of the centrifical springs, that little bushing arrangement or the vacuum advance setting . I dont even know where to port the vacuum canister to my holley 4160 vac 2ndary carb yet :rolleyes: .
Anywhoo Ill post what happens tomorrow and Ill take some install pics too..Maybe itll all just fall right in where its supposed to be :) That would be a first :lol:
Thanks again for making these procedures available to the lamer of us here...Its invaluable!!
