Years back I spoke with Kris about a new converter for my soon-to-be 400-powered '64 Tempest, running a 2.93 rear gear.
He built and sold me a 10" unit. Never got the chance to use it, I sold the 400 engine and the 10" converter a little later on because my direction changed on the car. At the time I was ordering the converter I was wavering between the 10" and a 13" unit, but I opted for the 10" to try to get better performance. I asked Kris about the fuel efficiency difference between the two and he said the 10" would sacrifice about 1 MPG compared to the 13" unit. On a side note, back when H-O Racing was still in business they had some converters in their catalog. If I'm not mistaken they were sourced from Continental, so one of the top Pontiac gurus at the time knew they were a good converter choice for a Pontiac application.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
