A.T. Trans question
The 73 corvette with the TH400 transmission, did they use the "switch pitch" Torque Converter ? or just an ordinary 350/400 converter?( I'm speaking of the one that acted normally (with not alot of slippage) "till you floor it, then it stalls high) Does anyone know of a source for a switch pitch converter new? Thanks

Switch pitch converters were limited to the Olds/Pontiac/Buick/Caddy family only, 1965-1967. I installed a modded unit from Kenne-Bell in my TH400 vette but a matching input shaft, front pump, solenoid and wiring had to be used with it. It gave a 3000 stall in high mode and 1800 in low mode at the flip of a switch.
I don't know if Kenne-Bell builds them anymore. Someone said P.A.E Peformance sells modded units.

I got tired real fast of the slippage of a 3000 stall converter on the street. Though not as efficient as a modern day lockup converter, flipping it to low stall acted almost like a stock converter. And they were stout units. Kenne Bell recommended flipping it to low stall right after launch under full load.

what converter to use?
I'm planning on running 9.5-1 compression & a 350/350hp cam, what did the factory use for a converter with the L46 option 350/350HP in 1969 ? & what rear gear did they offer stock? thanks
