Dustin:
I've been e-mailing jec2@gte.net in California who claims to
be doing performance mods for Hydra-Matics.
Hydra-matic vs. 700R4? Remember that the Hydro will not
give you an overdrive. It would be really cool behind a Jimmy 6
though. Stock truck Hydra-Matics shift at fairly low RPM, even at
full throttle. If I remember right, maximum is around 3700 RPM.
My 57 GMC V8 has one and I love it.

I don't think there was any significant use of automatic transmissions in
drag racing until the sixty's. at that time B &M Hydro was modifying the
early hydramatics and the 426 hemi dodge/plymouth started using automatics
quite a bit. Dragsters were still running direct drive/multi-disc clutches,
and spin the tires off the line, with NO tire growth.
