With the intro of the 400 sb and 454 bb in 70, I wonder how much figuring out how to externally balance a crank had to do with that. Was this a Chevy inovation, or was it a concept that had been around for awhile? With the limitation on "a" bodies in previous years, you'd think that if the technology existed, we would have seen 454's intro coincide with the 427 in the 'vettes and full size, as that is the only significant difference.

New to this board, this is an excellent thread. The 401 in my '65 Buick Wildcat is externally balanced on the flexplate, Buick may have used it on the original Nailhead in '53. Anyway, external balancing wasn't new technology in '70.

Talking Re: Question for mechanical engineers

FWIW..for those of us who remember Smokey Yunick and read his life story, he mentioned that Ed Cole once told him that the cost to produce a 265 V-8 when it first came out was about $55 each if I remember the quoted much for volume. Many of us still remember the over the counter price of the 340 hp/327 long block when they were released.....
