Uh oh. It looks like they may be catching on. Maybe they've been reading our site. If its true it maybe could increase the value of my old XJ. Just say it has the new stroker motor in it ha.

Yeah.. Chrysler just ditched 1/3 or their dealers and they are working on a over the counter stroker for archaic vehicles that they don't even totally support anymore. Pass your crack please...

The engine was developed using roller rockers to actuate upsized valves housed in new heads.

I wonder which roller rockers they are using? Also wonder if they will be available through Mopar?

An invisible engine would have been better.

they said the head was redesigned with larger valves.........Wish they would have made it a flow thru head design and move the cam up there for the roller rockers to run on........... that should take car of the harmonic problem...........Ya, ya ya, i know Pipe Dreams
