Opinions please, what mpg for 370's or 408's?

Down for a year, while I researched,... 1 LT1 swap later, 3 blown trannies, 1 blown rear, & now it sits...down AGAIN! Currently blown tranny & rear. It has taken a back seat to my 04. I lack an unlimited amount of $$$.

FWIW I would drop down to 3.73s for a RPM drop but still have some performance. I know that wasn't an option, but my RCSB N/A Ls1 243s and 1.8 rockers is knocking down 21 at 65mph. 16/17 at 80. I'm shooting for low to mid 20s at 80 with the home brewed turbo setup.

Sorry to hear that. Your truck ran hard. trt will have my short block in a few days but I have to wait about a month on the heads. I wonder if the manifolds will have to be ported to match the larger exhaust ports of the Patriots?

Aren't LA freeways like drivin in the city, bumper - bumper, a constant PITA? That's decent mileage w/ a 5.3, must be them 3.23s.
