I recently was gifted the "1974 Pontiac (350 & 400 V8 Orange Engines) Chassis Shop Manual Supplement" This manual verifies the use of the 400 sbc in Pontiac B Body Wagons made in Oshawa.
This has been a question about the use of the 400 small block in the B body line that we have not been able to confirm until now. The book is dated January 1974 Oshawa, Ontario. The engine specs are as follows:
400 V8 4BBL Single exhaust
180 Net HP @ 3800
290 lb ft @ 2400
RPO LT-4
There are 4 versions of the small block in this book as follows:
LeMans RPO L30 145HP 350 2BBL auto & manual Pontiac RPO L30 145HP 350 2BBL auto Pontaic RPO LM1 160HP 350 4BBL auto LeMans RPO L-48 185HP 350 4BBL auto Pontiac* RPO LT-4 180HP 400 4BBL auto
* "B" Wagon Only
Just my observation in the charts, 'Pontiac' refers to the big car or B body line and 'LeMans' to the A body line. It does not imply that a LeMans is it's own marque.
Models covered are Domestic Laurentian, Parisienne Brougham, Catalina, Le Mans, Le Mans Sport and Luxury Le Mans

Yes, Ray. I was around when the smaller carlines were introduced and it was assumed that Pontiac meant "full-size". Similarly, in the early 60's, Chevrolet meant "full-size".
If a guy was telling you about a specific car, when he said Chevy, we understood he was talking about the full-size car. Otherwise, he would say, "Chevelle" or "Chevy II", etc. He would never say, "Chevrolet Impala, or "Chevrolet Chevelle", unless he was just trying to mess with ya.
