My 331 n/a should make 325rwhp. with a aode and 3.27's i still got 20+mpg, i only got 650 miles before the thrust went out, so soon i will post my mpg. that was without a tune also.
i have eddy rpm heads, rpm 2 intake, xe270hr-114 cam, 30lbers, 75mm proM, and no tune.

Crank thrust bearing? Same thing happened to mine the first time I put the new low phosphorus oil in it.
