I thought my Dart got lousy mileage

Looks like the gages are an add in. I have seen some top alcohol dragster cockpits there isnt much in them. In fact a buddy of mine has a BBC top alcohol digger and he has a tach, boost, and oil pressure. Thats it. BTW its an injected 500 inch big block chevy. 13 to 1 static compression , and total is 25 to 1 over driven with the blower. About 2,500 hp. he runs a mopar 8&3/4 with 489 chunk behind it. Says they dont blow up. I say awesome torture test for the mopar rear. He rolled it out of the trailer one day and started it up in the driveway next to his dining room window, and blew the dining room window out. Whoops LOL.
