I have 262AH in my car. Reason for it was I always found the 2V to really lack low end grunt and I assumed at the time I'd be going with a Centri-blower one day so power band would be even more peaky. When I installed the cams 9-10 years ago they were the best off the shelf option that didn't sacrifice down low power but provided a decent bump on the top end. Hindsight being what it is I wish I would have gone a bit more aggressive on the cam selection and instead ran a Positive Displacement blower.
