Scott,

I am of the opinion that if you removed all the California emissions control "stuff" you wouldn't feel any seat of the pants
improvement, you might see it on a dyno.

Johnny,

Also there are specific part numbers for California carbs.

I >think< about the only difference on my '76, which was a CA coach originally, a second vapor cannister in series with the first
one, and a thermo switch on the distributor vacuum plus a slightly different carb - it lists under a different number. I can't tell
any difference in how it drives or the mileage from the 49 ones. After 76, there may be nore difference. Any of the gurus know of
anything else different on a '76?
