Looking at buying a 383 Stroker kit and a ZZ9 cam very soon for my LT1 and i was just wondering how much more the gas mileage has sucked for the guys that have done this... i could tell mileage went down after i installed my CAI. i have an A4 trans.

-Thanks

 

I get about 15-16 in the city and about 18-19 highway..

I get about the same as Cody, just maybe a mile or 2 less in the areas mentioned. Ooooh I even got a 97 also.
