Bill Thomas also was used to promote the extensive available modifications availble to a 396 thru his "Bill Thomas 396 performance book". This is the one quoted by Ludvisgren as saying the 396 made 442 HP out of the crate. It did'nt mention the blue print and balance job that happened once it was out of the crate.
Great book, type face looks almost identical to the Chevrolet 1965 Interim shop manual for the 396 and Tubo Hyra-matic. Happy to take other opinions on this but looks like they put Bills name on 'their' publication
