One thing you guys are missing is that when you order the short block it comes with the crank, rods, and pistons assembled at the factory. Its probably just a typo or error that it lists the short block for both applications. But , it could be that the bottom end is identical in both motors. The difference between the compression ratios could be a thicker head gasket. I'm sure I'll find out soon.

I'm just trying to find out as much info as possible before I start tearing my motor down. If its pistons I need to change or the crank and rods etc.... I will be going for an 8:1 compression ratio.

I've read so many threads where the members on this forum post negative replies about how this won't work, get a SRT, etc.... ( I'm not implying that any post so far have been negative). If you are one of those people please don't reply to my post. I couldn't care less about my warranty, gas mileage, driveability, and whatever other quips you have about not modifying the xfire. And no, I'm not here to sell anything to anyone. Any information I gather I will gladly share with any of you.
