i have searched all over and still cant get a clear cut answer.is the M-6010-A46NA block a exact replacement block for my 06 gt or not?i dont want to drill hole,trim parts,or have to leave parts out because there is no hole for it.i simply want to build a spare short block so i can keep my stock one and i dont want any surprises.oil pan,timing cover,valve covers, what ever needs to fit since they will come off my stock motor.
