Will 2003 engine fit in Gen II?

[JonB]

NO. Or Maybe. The exhaust is definitely NOT interchangeable, and the intake system and hood clearance may be an issue as well.

NO carryover parts on VGX motor except head gaskets and some rod bearings. Neat that CAAP will build the Viper Truck motors !

Although we have been told it will not fit, maybe it will have to....

Gen I engines are no longer available, in a few years the same will be said for Gen II engines. That will leave only engines out of salvage Vipers or the Chapter III engines for those needing them.
