I am looking at this

Does the block need to be machined to use the T. bearing?
Do i even need it?

Would this be just as good?

Will these fit under the stock timing cover?

thanks

 

I dont know what your smoking but that link doesnt lead to a timken/torrington bearing...


BTW basically any double roller timing chain is good enough for street apps.




Edit: Ok now i see, the link was to application not overview...

 

A Torrington behind the cam gear is only necessary when there's ALOT of force pulling the cam into the block; either a solid flat-tappet with very high spring pressure, or a solid roller.

They're almost never needed with any hydraulic cam, flat or roller. They won't hurt anything though, except your checking account.

IIRC the cam gear in the 3500 set is machined such that it just installs normally. No machining on the block is required.

Either of those sets will fit under any timing cover. Some blocks however require a little grinding, the timing cover bolt bosses or other features can interfere with them.

 

thanks for the replys. i was just reading another post about some blocks needing a little grinding.
