In the back of the book there is a page with Distributor specs. I need some info for the 402 or the 400 at the bottom of the page.
1 All the centerifugal advances, degrees and advance should be four
2 Vacume advance, degrees at HG should be two
3 Ignition timing, How many degress BTDC
Then on the engine page can you give me the compression ratio for the 402.
I have a 70 service manual but I have a 72 402 and want to see if there is any differance. Thanks Gary
