So after my introduction (which stated a 4BT conversion soon) I see an article featuring a 3.8 to 4.1 Stroker kit available from 505Performance. Article was featured in Four Wheeler magazine. The kit uses offset ground crank so fixes the spun bearing issue using stock type bearing shells and also addresses the oil burning issue with good old fashioned oil rings installed in a new stroker forged piston. They also use better rockers on the existing shaft (good old Mopar for the shaft) and modify the heads in the exhaust ports and 5 angle grind. All in all they are quoting roughly 340ft/lbs & 240-260Hp with a little better economy. This will still be a $7000hit but at least I don't have to go find parts and pieces as all stock parts fit.
My questions here are; has anybody in the Calgary area done this conversion? Is there a machine shop one would recommend to do the machine work? My reason for the change back is the engine would remain to be compatible with the CPU systems etc, I would add a heavy flywheel and I intend to jump on a Diesel Rubicon if they ever get here so my 2008 would be a sellable item still. Any comments will be appreciated.
