I as many others have been waiting anxiously for seems like a year or more now for the XR-2 to show it's face. It was my understanding that one of the primary purposes of the XR-2 program was to provide a platform for the P7 heads that could use many existing LA engine parts.

From what I have been able to determine there's not a heck of a lot of LA parts that will be usable.
- Certainly the top end will be totally different with the P7 hardware.
- Camshaft will not be usable. Must use special 60mm cam core. Did someone have a stockpile of parts they needed to move??
- Lifters from an LA engine will not be usable, totally different lifter layout.
- Pistons will have to be custom for the P7 chambers.
- There may be some applicability for existing crank and rods??
- Timeing chain/gear drive??
- Timing chain cover will be usable!!
- Damper will be usable??
- Pan will be usable??
- Distributor will be usable??
- Hopefully the bellhousing bolt pattern will be LA??

If I'm wrong I sure wish someone would set me straight, I'm getting a very uneasy feeling about exactly what will be required to put together a strong XR-2/P7 combination!!!
