Should I do new jack shaft and bearings?

[powerstroke 350700]

Just wondering if it is a weak point I should address, then there are gears and chain? Also what about spark plugs I hear there are better ones to use! Whos would you go with?

I did the whole TCL delete with jackshaft and all. But before the TCL delete I had the evo manual chain installed after I took out a chain case. Havent had an issue since. Did the evo chain as well when I did the TCL delete. Never heard anything about spark plugs before.

Spark plugs...

Some riders have experienced "flame out" when running more boost. The iridium plug isn't really designed to have the gap altered, so an NGK CR9EB is a good solution (Thx EVO). With a Big Chute turbo, I'm running the gap at .018"

After doing Mulitple EVO/Turbie TCL deletes I am very positive that the AC design with the motor mounts/TCL is junk. The mounts are super sloppy. Why would you need or want the engine to move that much in the chassis. Then the fact that it is moving allow the jackshaft to move all over the place. It allows bending of the jackshaft under flex. In my opinion I would not just do a jackshaft by itself. Lock that motor in place with rigid rubber mounts and stronger mounts. Then stop allowing the jackshaft to twist and flex because the stock bearings allow it. To my knowledge the only product that will stop this is one that deletes the TCL.
