My 454 Suburban twed our 32 trailer like nothing. The gas mileage really sucked bad though.
Good to know. As for the mileage, that's what I'm hearing...Guess I'll start looking for that second job to feed this monster then ;)
I checked it 4 times this summer and every time got 4 MPG. Yes that is right 4 MPG. I think it had a ECU problem sending the EFI into a default of full rich setting cause I have never seen anything that bad.
The 1 ton dually with 454 I just bought was converted over to a carburetor and on the way home from buying it I got 10 MPG. The next day I noticed that the vacuum advance was not hooked up and the electric choke was stuck part way closed, so I am hoping to get 13 MPG once I fix a few things. I will be thrilled if I get 8 MPG pulling the 5er
