Title: Timing 1967 Shelby 428. Anyone have the spec?
Post by: 67428GT500 on August 05, 2019, 08:45:29 PM: I can't locate my performance manual and I am setting the distributor in. To my recollection is was about 6 degree BTC. Can anyone this?

Post by: 67428GT500 on August 05, 2019, 08:55:31 PM: I thought it was originally set at 16 or 18 and 38 degrees to total at 2700 rpm. Been a while.

I posted a request for factory initial timing according to Shelby spec. I remembered the factory decal was still on the head and used it for reference. The original decal on the head is showing 6 degrees BTC. However, to drop the distributor for initial start up timing I used the CJ spec and turned the damper to 10 degrees BTC and dropped the distributor in on number one.
