The last one in your list matches the cover. copyright 1987

The section I was refering to is titled "Road-race Tuning" on p. 123
- in it it suggests 30 or 40 mph to 80 mph, and specificly to crowd the vacuum readings down to the PV opening. This is to get the best main jets.
It follows a section titled "special Procedures for 'Wild' Camshafts. That section has diagrams showing the proper transfer slot to throttle relationship.
The chapter is titled Carburetor & Performance. There's a drawing of a 413 long cross ram in cut-away view on the chapters first page. Very cool picture.

(I also have the little 4150 book but its redundent to the big book. I keep the little one in the garage for reference.)
