What kinda mileage am I looking at?

[Phatt_daddy]

I am picking up my block from the shop tomorrow and starting the assembly of it in the next few weeks. Stock 5.0 block bored 30 over with a stock cam and a set of reworked 351w heads. Keeping the sd and injection, going with a 3.55 gear and a tune. what kinda gas mileage could I be expecting with this setup? It is also a 5-spd.

Thanks,
Nate

lol Thats like pickin lotto numbers.....it all depends on how you drive. My 347 is great on the highway and if I drive it like my papaw (around 18 mpg). Driving it like I usually do its more like 14.
