LT1/4 Stroker MPG?

Ok whos running a LT1 stroker and what cam and MPG are you getting? I am just about to drop in my new motor and am wondering what type of hit I will take with gas milage. I went with the CC 306 with my set up. My current motor is now getting 17MPG in town and 25MPG HWY (LT1 ported heads, LT4HC, 1.6 R/Rs)

My 381/11.9/GM 847 engine gets 24 on the highway, 15-17 in town...depending on how heavy I am. I'm sure I could squeek out 19 in town if I drove it nicely...

6 speed does nice things...

Great the 847 has very similar duration to the 306 just a bit more lift, so it sounds like I should be able to keep my gas milage around the same with proper tuning. 6 speed and fuel injection, gota love it.
