505" with 10.3:1 CR and small .545 Howards hydraulic roller. I usually run 91 no ethanol pump gas but can run the cheapest pump gas out there with no issues. The 11" converter and 3.54 gear makes it a pleasure to drive on the street.
The last time I checked mileage on an out of town trip, it pulled down 11 mpg. It essentially behaves like a super sized 440. More of EVERYTHING!
It weighed over 3,700 lbs. (with driver) the other day after I got it home from the track. It runs 11.1 @ 121 n/a and ran 10.01 @ 133 that day with a small shot of nitrous.
The best part is, it is very low maintenance other than having to change drag radials like you change diapers on a baby!
