Those are some definately good numbers for that car. If it indeed had work done by Sean then you can guarantee that it's a runner
But dyno's aren't always "accurate". Theirs too many variables involved with dyno's. I was talking with billy up there at his shop and he said he prefers his customer's motors to be dyno'd just with the motor..not in a rear wheel dyno. I suppose the dyno could be off..but if it's a sean hyland motor as i stated above it very well could be putting those kind of numbers down.
