318 2bbl to 4bbl: Is it worth it this time?

I got 20 MPG Hwy. in my 360/904/2.76 rea with 26 inch tires Dodge Magnum.

If a 318 can't do it in an A body, you ethier need to go back and tune that baby up or replace the engine or trans cause something aint workin right.

The T-Q should be the smaller primary unit. Get ahold of Demonsizzler for tuning jets. (And advice on a T-Q carb to look for. I don't know if a smogger T-Q would be OK) Advance the timing some and a great MPG netter would be a MSD or equal. The multi spark really helps in mileage.

Between the smaller primary of the T-Q and multi spark, you'll gain mileage. If you had a 2.76 gear out back, you would do really well.
