[65 pile]

I have read multiple threads about jetting carbs at higher altitude. I have taken the advice (Tom V. from this thread, http://forums.maxperformanceinc.com/...78#post5749478, post #7) from a previous thread and used the air density at a certain altitude to calculate the difference. According to these differences, I am at 14% reduced at 5,000 ft. here in Loveland, CO.

I pulled the jets from the center and rear carbs. They were #64 in the center and #68 in the rear. I guess the car ran well in Lancaster, PA, which must be somewhat near sea level. I really don't remember, it always smelled rich, but didn't stumble like it does here. I do know it could spin the tires there if I tried and it would sometimes get scratch when I hit second. Out here it stalls if I try to light them up.

Anyway, I just wanted to run my choice of jets by everyone before I went and spent the money on them. The car is a 4spd. with a 389 tripower. I think there was some work done to the engine before I got it, but I don't feel it was too radical, and certainly don't remember what the seller told me (who knows if it was accurate). So, based on the jets that were in the vehicle, and the fact that air density is reduced by 14%, I came up with #59s in the center carb and #63s in the ends. I know the ends are supposed to run a little rich compared to the center. Would anyone recommend #64s in place of the #63s?

Thank you to anyone who offers any advice. This forum has always been very, very good to me.

Happy New Year.
