cams and mileage?

[andrew69_04]

just curious what kind of gas mileage all of you out there are getting with aftermarket cam, springs, heads, ect. I just put my 224/231 in lastnight and was curious how much mileage i will lose by havin a big cam over my stock one.

driving sane on the highway you won't lose much at all, I lost 3 mpg on the highway, lost 5-7 in town (I installed a 3600 stall too so that hurts too), and when I get on it it's shit. I use probably 3/4 gallon per 1/4 mile pass

doing 80 mpg i was getting about 300 to a tank

12 city/20 hiway. But I still have some tuning issues to work out. With a good tune you shouldnt lose much....some have even seen increased mileage.

I average about 15mpg with a TR224. Thats mostly city driving tho.
