Ima Keep it short. Just swapped out the stock block on My '04 Mach. Just curious as what the power difference could be. Main reason for asking the 1.3 CR Drop.

Yeah she's set up for Boost.... But still N/A

Most stroker kits add power. As to how much I am not sure, especially with the lower compression. A 4.0 to 4.3 kit "is supposed to add" 30 hp and 30 tq, but I am sure that is a pure N/A build. I would say around 40hp and torque more or less, but I have been wrong before.

I do know that it will probably run better because everything is brand new. No wear and tear if you know what I mean.

Get it DYNOed!!!

I don't plan to get it dynoed for awhile. To be honest, I'm expecting almost a 5% loss in power.
