I don't know yet. I'll find out tonight or tomorrow.

Hey Billa, if I drive reasonably, what kind of gas mileage do you think I can expect with the 355 engine you mentioned above? If I go with new Vortec Heads and a Vortec-Style Edelbrock Performer Intake/600 Edelbrock Carb.

Also, should I have the new Heads and Intake manifold port-matched or is that a waste of time/money?

And lastly, what sort of fuel economy difference should I expec when switching from the stock 29 inch rubber to 33x12.50's?
